Hi everyone!
I'm a solo developer and I've built a free logic puzzle game for Android called Eitanium.
It's a grid-based deduction puzzle in the spirit of Einstein's Riddle / Sudoku — you use clues to work out where everything belongs.
No timers, no pressure — just relaxing brain-teasers.

I'm in Google's closed testing phase and I'm looking for people to try it out and help me get it ready for a public release.
It's available worldwide and 100% free.

⚠️ Please follow these 3 steps IN ORDER — if you skip straight to the Play Store you'll get an "Item not found" error:

1️⃣ JOIN the tester group (use the same Google account that's on your phone's Play Store):
https://groups.google.com/g/eitanium-testers

2️⃣ Then OPT IN as a tester — open this on your phone and tap "Become a tester":
https://play.google.com/apps/testing/com.eitanium.eitanium

3️⃣ Then INSTALL from Google Play (wait a few minutes after step 2):
https://play.google.com/store/apps/details?id=com.eitanium.eitanium

Tip: don't search for "Eitanium" in the Play Store — test apps don't show up in search.
Use the install link directly.

Happy to test your app back if you drop a link below.

Thanks so much — every install genuinely helps a solo dev get this over the line!

Hey all — solo dev here, grinding the 14-day closed test like everyone else.
Drop your opt-in link in the comments and I'll join yours right away and keep it the full 14 days.
Join mine, comment "done," and I'll return the favor immediately.

My app:
Eitanium — a calm, Einstein-style logic deduction puzzle.
30 levels, a daily puzzle, no timers, no pressure.
(Android only.)

Join mine:

1. Join the group: https://groups.google.com/g/eitanium-testers → tap "Join group"
2. Opt in: https://play.google.com/apps/testing/com.eitanium.eitanium → tap "Become a tester"
3. Tap the "Download it on Google Play" link → install → open it once

So it counts for both of us:
• Use the SAME Google account in steps 1–2 and on your phone's Play Store.
• Join the group FIRST, then the opt-in link (give it a few minutes to sync if it says "not a tester" yet).
• Please stay opted in for the full 14 days.

Comment your link and I'll join right now.
Thanks, and good luck clearing your requirement too!

P.S.
i'm new to all this, so Claude Code told me what to write here... LOL
