Hi!
I built ChessGMDoku, a free daily puzzle game where you name a chess GM/IM that matches two criteria (country, title, tournament won, world champion beaten...) at the intersection of a 3x3 grid — same idea as the "Immaculate Grid" games but for chess.
I'm looking for 12 closed testers before the Play Store approves it for public release (Google's requirement). It takes 2 minutes:
- Open this link on your Android phone: https://play.google.com/store/apps/details?id=com.chessgmdoku.app
- Tap "Become a tester"
- Install from the Play Store
You just need to stay opted in for 14 days — no obligation to play daily. Please send me your Gmail/Google account by chat/DM so I can add you to the tester list.
Feedback very welcome!
