Polyominoes are figures created by attaching multiple squares edge-to-edge. They are sorted based upon the number of squares they have.
Henominoes EditThere is a single henomino, consisting of one square by itself.
Dominoes EditThere is a single domino, consisting of two squares attached edge to edge.
Trominoes EditThere are two trominoes: the I tromino, consisting of three squares attached in a straight line, and the L tromino, consisting of a square with two other squares attached to the top and bottom.
Tetrominoes EditThere are five tetrominoes - the square tetromino (consisting of four squares in a square shape), the line tetromino (consisting of four squares in a straight line), the T tetromino (consisting of a square with three squares attached directly to it) and the L tetromino (consisting of three squares in a line then an additional square on the bottom at a right angle).
There are twelve pentominoes. These are named, by their approximate shape:
- Line pentomino
- L pentomino
- P pentomino
- R pentomino
- S pentomino
- T pentomino
- U pentomino
- V pentomino
- W pentomino
- X pentomino
- Y pentomino
- Z pentomino
