Beavers love bominos. Bominos are patterns made of tiles, arranged in a grid.

The tiles of a bomino must satisfy these conditions:

Each tile touches at least one other tile (horizontally, vertically, or diagonally)

There is at least one pair of tiles where:

the two tiles touch diagonally AND

there is no tile that touches both these tiles horizontally or vertically.

A bomino with n tiles is called an n-bomino.

All other arrangements of two tiles that satisfy the bomino conditions can be rotated or flipped to produce the same figure.

Task:

There are three possible 3-bominos (bominos made of three tiles).

Create them below.

Click on an empty tile in a grid to fill it.

Each 3-bomino fits in one grid.
