Requesting RiftCompare feedback
Hi r/Riftbound,
My name's Bill and I'm the person behind RiftCompare (riftcompare.com). I got into Riftbound early and quickly ran into the same problem a lot of you probably have: prices are all over the place depending on which store you check, and there was no easy way to see who actually had a card in stock for the best delivered price. So I started building a tool to solve it for myself, and it grew from there. It's free, independent, and there's no sign-up.
Over the past while I've been overhauling and adding a bunch of things, and I'd love to walk you through the main ones and hear what you think:
Live price comparison. Search any of ~1,429 cards and see every store in your market side by side, ranked by total delivered cost (item + postage), plus eBay and TCGplayer. Right now there are 10,000+ in-stock listings updated daily.
card page showing the store-by-store price comparison table
Today's Top Deals. A daily-refreshed view of the biggest savings and cheapest sealed product in your region, so you can spot a good buy at a glance.
Multi-region and multi-currency. You can switch between AU, NZ, US, UK, SG and CA and see prices in your local currency, pulling from local stores in each market.
Full card database. Browse everything by set and domain, so you can dig through the whole collection rather than just search one card at a time.
the database / card gallery view with filters
Pack opening simulator. A fun one: rip free virtual Vendetta packs with real pack odds and live prices on every pull.
Daily Riftle game. Guess the daily Riftbound card in 8 tries, a new one every day.
I'd genuinely love to hear what you think of RiftCompare in its current form. What features are you missing? What do you actually use and love? What's there but could be better, and how? Are there stores in your region I should be tracking that I'm not? I've always valued community feedback and a lot of what's on the site came from listening to suggestions, so please be constructive and let me know. Thanks for reading, and thanks for checking it out!

I made a market Index for Riftbound Cards
Hi All,
I'm the owner of riftcompare.com, a website for people to compare prices of riftbound cards and acts as a price database.
I just discovered this sub and realised that a feature I've made called the Riftcompare Index might be quite useful to see how the market is performing. Feel free to check it out:
https://riftcompare.com/market
I also have automated daily market wrap reports here:
https://riftcompare.com/market/wrap
Would love to hear any feedback. There are some other features I've hidden for now such as cards that are rising in demand - but let me know if you'd like to use it. DM me and I can give you a link.

New P2P Riftbound Marketplace for AU/US/UK/NZ/SG players.
Hey All,
I run RiftCompare - (the price comparison site for AU/NZ/US/UK/SG Riftbound singles). We just launched a P2P marketplace built into the site and wanted to share it here first since you're the people who'll actually use it.
How it works:
- Anyone with a verified email can open a shop and list cards — no seller fees to list, just a 5% cut when something actually sells
- Buyers pay through Stripe Checkout; the money sits in escrow and only releases to the seller after you confirm delivery (or automatically 14 days after it ships if you don't respond — you're never on the hook to manually approve every payout)
- Built-in messaging so buyers and sellers can actually talk to each other about an order
- If a seller doesn't ship in time, you're auto-refunded in full, no argument needed
It's in beta. That's not a throwaway disclaimer — I mean it's genuinely new, and I'd rather you break it now and tell me than have it fail silently on a real trade. There's a "Found a bug? Report it" link on every marketplace page that goes straight to me, or just reply here.
Link: riftcompare.com/marketplace
Would genuinely appreciate anyone willing to list a card or two, or even just poke around and tell me what's confusing. Vendetta drops July 31 so figured now's the right time to get this in front of people before that hits.

I built a pro-draft win-probability tool based on Champion Draft for statistical enthusiasts
With MSI on I kept arguing with friends over whether a comp had "won draft," so I built a small site that estimates blue-side win probability from real pro data (Oracle's Elixir — thousands of games, patch-weighted, current patches only).
How it works:
- Pick 5 champs a side → win %, plus a breakdown of champion strength, synergy, and lane matchups.
- Optionally pick the two teams → it adds team Elo and the actual starting players' Elo + their history on the champ they're on. Rosters auto-fill from each team's last game, and you can edit a seat to sub someone in. Keyboard-friendly (type a champ, hit Tab/comma to lock it and jump to the next).
The honest part, because this sub will (rightly) ask:
- Draft alone is a weak predictor. Champions-only sits around 55% accuracy - barely above just picking the favorite - because who's playing the comp matters far more than the comp. Add the teams and it climbs to ~66%.
- It's worst at international events like MSI, where cross-region team strength is hard to calibrate (the tool flags cross-region matchups so you don't over-trust them).
- Everything's validated with walk-forward backtests (no peeking at future games), and the methodology page shows accuracy broken down by league and patch - plus a list of things I tried that didn't work.
It's a draft-analysis / what-if toy, not a betting edge - pro games are genuinely hard to predict and I'd rather be honest about that.
(Optional, caveated solo-queue line - I'd cut it, but if you want it:) A few people asked about solo queue - the draft-only champion/synergy read can loosely sanity-check your own draft, but it's trained on pro games, so treat it as a rough guide at best.
https://comp-strength.vercel.app/ (haven't bought a domain yet) - would love feedback, especially on the modeling. Hobby project.

I made a free Pokémon card price database (DexCompare) that compares prices across every store
DexCompare is a price database for Pokémon cards. Search any card and it shows what it's selling for across stores in AU, NZ, US and UK, so you can find the cheapest place to buy. Sealed product's in there too, and it's completely free with no signup.
I built it to be the fastest way to check a card's real price without opening ten tabs, and it does that well. I'm still adding stores and features, so if there's something you'd want in it, I'd like to hear it. dexcompare.app

Built a price-comparison tool for the One Piece TCG — looking for feedback from people who follow the market closer than me?
Prices on this game swing harder than anything I've collected — one price this week, double the next. So I built OPCompare: compare a card's price across stores (and regions) in one place so you can see what it's actually going for before you buy or sell.
It's a newer game so I'd really value feedback on getting it right:
- Which stores and sets should I prioritise first?
- Is the data accurate for the cards you track, or way off?
- What's the one feature that'd make this actually useful to you?
Full honesty: it's a work in progress and the data's thin in spots, so there'll be prices that aren't right yet. Sorry in advance — and if you call them out, that's exactly what I'm hoping for.
, free. ( I'm posting for the feedback, not a pitch.)

Built a card price-comparison tool to scratch my own itch — looking for feedback on what's missing before I take it further?
Singles pricing does my head in — every store's a few bucks different and "market price" never matches what I actually pay. So I built MTGCompare: search a card, see prices across stores (and regions) lined up in one view, find where it's actually cheapest.
I'm posting mainly because I want feedback from people who buy way more than I do. Specifically:
- Which stores do you use that I should be pulling prices from?
- Is the regional comparison (AU/US/UK) actually useful, or just noise?
- What would make this genuinely replace your current price-checking routine?
It's still very much a work in progress, so there are prices and listings that aren't right yet — apologies in advance for those, and if you spot one, telling me is exactly the kind of feedback I'm after.
— free. Be as brutal as you like!

The same card can be 30% cheaper in another region right now — I built a tool that shows the gap across AU/NS/US/UK
I got sick of opening six tabs every time I wanted to know if a card was a good price, so I built a thing that pulls prices for the same card across stores and regions into one view. A few findings that surprised me while building it:
- The same card can swing [X]% between AU and US listings once you factor shipping — sometimes importing genuinely wins, sometimes it's a trap.
- The "market price" you see on one big site is often well off what the card actually sells for elsewhere that week.
- [drop in one real, specific example — e.g. "a sealed [set] booster box is $X cheaper from [region] right now even after postage"]
It covers 20,000+ cards across every set, sealed product too, and shows the spread across stores and the AU/NZ/US/UK markets side by side so you can see where it's actually cheapest before you buy.
It's at dexcompare.app if it's useful to you. Genuinely keen for feedback from people who buy more than I do — which stores am I missing, which regions, what would make it actually replace your tab-juggling?

Because you guys liked Riftle — there are now 7 more free Riftbound minigames for the community
Riftle's reception here made my week, so I kept building. Everything's free, browser-based, built on live card prices:
- ⚖️ Higher or Lower — which card costs more? One mistake ends your streak.
- 🏷️ Price Check — The Price Is Right: guess each card's market price, score by closeness.
- 🔍 Zoomed In — name the card from a tiny patch of its art.
- 🧠 Pairs — memory match with real card art.
- 🎁 Pack Opening Simulator — rip virtual packs of real cards and see what your pulls are worth. No money, all the dopamine.
- 🧬 Riftbound 2048 — slide and merge cards up the rarity ladder, Common to Legend.
- 💥 Card Smash — whack-a-mole with cards. Pricier cards score more; don't hit the bombs.
And 🃏 Riftle is still going daily (midnight AEST) with an Unlimited mode.
All of them: riftcompare.com/games — feedback and game ideas very welcome.
(Transparency as before: my site, games are free and stay free.)

I made five little Pokémon card minigames for my mates, and they won't stop sending me smug emoji grids. So now it's your problem too. (Free, browser, no signup)
A few months back I showed my mates a dumb little game I'd hacked together — guess the Pokémon card from its blurred art, Wordle-style, sharpening with every guess. Their feedback was split between "one more, do another one" and "you should be able to smash the cards." So naturally I lost several months of evenings, and now there are five of these things. All free, no signup, they run in your phone browser:
Dexdle is the blurry one. 8 guesses, and each guess tells you if you're close on the set (newer/older arrows), type, rarity, HP and what the card's actually worth. The moment a Base Set common you haven't thought about since primary school resolves out of the blur is genuinely emotional. New card each midnight AEST, unlimited mode when that's not enough.
Price Duel is higher-or-lower with real market prices, and it is a humbling machine. Twenty years around these cards and my best streak is single digits. My mates are worse, which is the important thing.
Pack Rip Simulator lets you rip a 10-card pack from any modern set and watch the value tick up as you flip, then tells you whether your pack beat the price of a real one. (Labelled clearly in-game: simplified odds for fun, not real pull rates. Your wallet is safe.)
And for the people who wanted violence: Card Catcher has you catching falling cards in a binder while dodging fakes, and Bulk Breaker is Breakout where the bricks are real cards and the holos take two hits. Your score is the dollar value you caught or smashed. Smashing a chase card you could never afford is the healing part.
Weird side effect: because everything runs on live market values, after a week my mates just knew what cards were worth. Years of me talking at them achieved nothing; a higher-or-lower game did it in days.
They're all at dexcompare.app/games (Dexdle's at /dexdle). Tell me what's too easy, what's broken, and what I should build next — and yes, Dexdle's share button makes the smug emoji grid. 🟩🟨⬛
(Transparency: it's my site — a card price-comparison side project. The games are free and stay free; this is just me making the database fun.)

I turned a Pokémon card price database (20,000+ cards, live prices) into five free browser minigames — daily Dexdle, Price Duel, a pack rip simulator and two arcade games. No signup.
Hey all — I run DexCompare, a Pokémon card price-comparison site, as a side project, and I kept thinking the card database would make a fun game. It became five. All free, no signup, work on mobile:
⚡ Dexdle — daily Wordle-but-the-answer-is-a-card. 8 guesses, each giving feedback on set (newer/older arrows), energy type, rarity, HP and market value while the blurred art sharpens. New card at midnight AEST, plus Unlimited mode for one-more-game brain.
⚖️ Price Duel — higher or lower with real market prices. This game has humbled everyone I've shown it to, including me, and I literally run the price site.
🎴 Pack Rip Simulator — rip a simulated 10-card pack from any modern set and watch the value tick up as you flip, then see if your pack "beat" the price of a real one. (Clearly labelled: simplified odds for fun, not official pull rates.)
📂 Card Catcher & 🧱 Bulk Breaker — Flash-era arcade throwbacks. Catch falling cards in a binder while dodging fakes, or play Breakout where the bricks are real cards and holo chase cards take two hits. Your score is the dollar value you caught/smashed.
The bit I'm weirdly proud of: everything runs on live market prices, so you accidentally absorb what cards are actually worth while playing. And because it's all one database, any card that catches your eye mid-game links straight to its live price page across AU/NZ/US/UK stores — that's the comparison site doing its day job, and (full transparency) the ads and affiliate links over there are what keep the games free.
Too easy? Too hard? What should I build next?

I made Dexdle — a free daily "guess the Pokémon card" game where the blurred art sharpens with every guess (+ 4 more card minigames, no signup)
Hey everyone — I run a small Pokémon card price-comparison site as a side project, and I kept thinking the card database would make a fun game. It spiralled. There are now five free minigames, no signup, no paywall:
⚡ Dexdle — Wordle, but the answer is a Pokémon card. You get 8 guesses, and every guess gives you hints on the set (with newer/older arrows), energy type, rarity, HP and — because I'm a price nerd — its market value. The card's art starts heavily blurred and sharpens with every guess. New card every midnight AEST, plus an unlimited mode when you inevitably want one more.
⚖️ Price Duel — higher or lower, with real market prices. You see one card's value, then guess if the next card is worth more or less. Sounds easy. My best streak is embarrassing and I literally run the price site.
🎴 Pack Rip Simulator — rip a simulated 10-card pack from any modern set and watch the value tick up as you flip. See whether your pack "beat" the price of a real one (clearly labelled: simplified odds for fun, not official pull rates).
📂 Card Catcher / 🧱 Bulk Breaker — two old-school Flash-style arcade games. One is catching falling cards in a binder (dodge the fakes, chain combos), the other is Breakout where the bricks are real cards and holo chase cards take two hits. Your score is the dollar value you caught/smashed.
The thing I'm weirdly proud of: every card in every game uses live market values, so you accidentally absorb what cards are actually worth while playing. Price Duel especially has taught my mates more about the market than I ever managed by talking at them.
All five are here: dexcompare.app/games (Dexdle is at /dexdle)
Would genuinely love feedback — too easy? too hard? what game should I build next? And if you get a Dexdle streak going, the share button makes one of those smug emoji grids. 🟩🟨⬛
(Full transparency: it's my site — the games are free and stay free, they're just my way of making the database fun.)

I made Riftle — a daily Riftbound card guessing game (think Wordle but for Riftbound)
Hey all — I've been a bit obsessed with the game lately and wanted a fun daily thing to test how well I actually know the cards, so I built Riftle: a once-a-day guessing game where you try to figure out the mystery Riftbound card from clues.
Each guess reveals how close you are across things like domain, type, cost, and stats — so it rewards actually knowing the card pool. New card every day, everyone gets the same one, so you can compare scores with friends. Free, no signup.
Full transparency: it's my own site (riftcompare.com/riftle), so mods please pull this if it's not allowed and I'll move it wherever's appropriate. Link if you want to give today's a go: https://riftcompare.com/riftle
Would love feedback — if a clue feels off or there's a stat you'd want compared, tell me and I'll tweak it. Curious what people's streaks get to.

I built a free tool that compares Chaos Rising restock prices across stores
Hi All,
Hey all — with Chaos Rising restocks being a mess to track, I got tired of having ~15 store tabs open comparing prices, so I built a small site that does it for me and figured the sub might get use out of it too.
It pulls current listings for packs, boxes, and cases and shows you the cheapest option across stores in one place. It's free, no signup, and I'm not selling anything or taking affiliate cuts — just a side project I made because I wanted it myself.
Full transparency: it's my own site, so mods please remove if this isn't allowed and I'll happily move it to wherever's appropriate. Link's here if it's useful: https://dexcompare.app/restock/chaos-rising
Genuinely keen for feedback too — if there's a store I'm missing or a feature you'd want, let me know and I'll add it.
Hope it helps!
