Pento solves seven different pentomino packing problems:

• 6×10 — 2,339 solutions
• 5×12 — 1,010 solutions
• 4×15 — 368 solutions
• 3×20 — 2 solutions
• 8×8 (with 2×2 square) — 16,146 solutions

• P Challenge — 1,017 solutions
• U Challenge — 1 solution

Sample solutions to the standard 6×10 problem and the P Challenge are shown to the right.

Plans for the future development of Pento include generalizing it to handle other packing problems, and adding the ability to create a file containing a graphical representation of the solutions.
