- Unlimited set of easy to medium puzzles;
- Symmetric puzzles or non-symmetric puzzles or let the app choose for you;
- Ability to change the board color from a predefined set;
- Undo/redo moves;
- Autocompletion of a cell so that the last empty cell in a row, column of area can be automatically filled with a double-tap.

Puzzles of Sudoku Free has the same gameplay as the paid version (Puzzles of Sudoku), with the following differences:
- Puzzles are easier to solve, even on the maximum level of difficulty;

- Undo/redo information has a limit on the moves that are tracked (hopefully a big one, but still a limit) and it's not persisted if you quit the app;
- Banners are shown while playing (no banners on the paid version).
