Pentominoes

Skewed Rectangles

  • 20x3: 2 solutions

    These are the same two solutions as the 3x20 rectangle above, just cut at the W pentomino and rearranged.

  • 15x4: 138 solutions

  • 12x5: 233 solutions

    This solution can be easily rearranged into a solution to the 5x12 rectangle above, but not all solutions share this property.

  • 10x6: 156 solutions

Misc

Pentominoes Plus the Square Tetromino

Pentominoes Plus the Monomino

One-Sided Pentominoes

These are just like regular pentominoes, except that non-isomorphic reflections (different shape when flipped over) are treated as separate pieces, and pieces are not allowed to be flipped.

Rectangles

The numbers of solutions for the last three puzzles above were taken from Gerard Putter's Polyomino Solution Page, as reported by Stephen Montgomery-Smith.
