This is a nice simple game that requires a little thinking, or a lot of trying.
The board is separated in 4 smaller sections each in 3 by 3 squares. In some of the squares are shown there is an icon. You can place the forms below in any of the 4 separated parts of the board to hide all or some of these icons.
The goal of the game is to have visible only the icons shown in the "To win" section.
All forms can be rotated. Some forms are smaller and can be slide to a new position the same area (board part) .
Hide the icons and win the game.

In settings you can:
- Mute the sounds (if someone sleeps in the room)
- Pick what and how many icons to be shown (there are a lot to pick from)
- What forms to be used or more than 4, what is in the list from witch the game will pick
- and more ...
