A logic puzzle that will keep your mind sharp. Three difficulty levels, and hours of challenging enjoyment.

The objective of Takuzu is to fill the grid. No more than two colors can be adjacent to each other, and there can be no identical rows or columns.

The top button can be used to check the current board and possibly give a hint. The bottom button activates other screen options, such as undoing moves or activating the menu. A long press will display the special access buttons, which is useful for Versa Lite and Versa 2 use.

Takuzu costs $ 0.99 after the two-hour trial period has ended.
