The game is fun and the provided 50 puzzles are enough to see if it’s worth buying more or not. The app itself is very smooth and intuitive to use.

Disclaimer: I am related to one of the developers (but my comments above are as an objective a take as I can provide).

### 5/5 — Fun puzzle game to pass the time

If sudoku/kenken or puzzles are your thing, this is a very simple and nicely done puzzle game. In-app purchases are more than reasonable for the amount of time you get out of it
