LITS


Translate this site.

LITS is a logic puzzle with simple rules and challenging solutions.

The rules of LITS are simple:
You have to place one tetromino* in each region in such a way that:
- 2 tetrominoes of matching types cannot touch each other horizontally or vertically. Rotations and reflections count as matching.
- The shaded cells should form a single connected area.
- 2x2 shaded areas are not allowed.

* Tetromino is a shape made of 4 connected cells. There are 5 types of tetrominoes, which are usually named L, I, T, S and O, based on their shape. The O tetromino is not used in this puzzle because it is a 2x2 shape, which is not allowed.
