Hi r/iosgaming, I’m the developer of VariantDoku, an iOS/iPadOS app for variant sudoku puzzles.

I built it because I wanted a cleaner place to solve logic puzzles on mobile: no ads, no trackers, no random guessing, and a library that goes beyond one daily grid. The app currently has 1,800+ variant and zero-givens puzzles, including Killer, Kropki, Thermo, XV, Arrow, Renban, German Whispers, Palindrome, Diagonal, Anti-Knight, and more.

A few things I focused on:

• Solve-time leaderboards for daily puzzles through Game Center
• A variant-aware advanced hint system that understands the puzzle’s constraints instead of just revealing random cells
• Offline solving for saved/library puzzles with Variant+
• Step-by-step tutorials for learning variant rules
• Candidate notes, corner marks, colors, symbols, hints, and error checking
• iPhone and iPad support
• No ads, free or paid

The daily puzzle is meant to be a small competitive routine: solve cleanly, compare times, come back tomorrow. But the larger catalog is more relaxed, especially if you like working through harder variant grids over multiple sessions.

I’d appreciate feedback from iOS puzzle players, especially around onboarding, the leaderboard flow, and what makes a logic puzzle app feel good for longer sessions.
