Review summary
Pros
- Brain-stimulating and mentally challenging puzzles that make you think
- Addictive and highly engaging; many players play daily
- Easy-to-use, clean UI with intuitive input options (cell-first or number-first)
- Flexible progression options with ads for free credits plus optional purchases and achievements
Cons
- Monetization-heavy: many puzzles require credits or purchases, creating a pay-to-play barrier
- Ads-based progression: progress often relies on watching ads for free credits, which can feel gate-like
- Account/signup friction: sign-up/credit system can be burdensome for new players

| 2026-08-03 | My favourite game for many years! I'd rate it 5 but for nonexistent support. I exhausted the games unable to add credit (up until then no problem adding credits). Emailed and waited and waited .. no reply but after a month or so more games! Now after adding several max credits I can't add any. I suggest 4 options for the developer (1) reply and add more games, (2) add a pop up that says no more games (3) give the option to start over (I've reinstalled, same thing), (4) ignore support | ||
