Meowdoku is a cat-themed sudoku variant that's highly addictive but plagued by intrusive ads. The game replaces numbers with cats and colors, following sudoku rules: only one cat per row, column, color, and no neighboring blocks. Players complete ten cats per level with three strikes allowed, earning hints through ads or rewards.

Daily challenges add replayability. As a longtime sudoku fan, I prefer Meowdoku over the classic version. However, Oakever Games bombards players with mandatory ads after every level and offers no premium ad-free option despite community demand.

Many users seek workarounds for the ad experience. While I continue playing despite the frustration, I hope for an ad-free tier soon.
