A classic geometry puzzle updated by the Prime Radicals team! Build an awesome PentoTower out of your solutions, and reach the pinnacle of brainy achievement. Pentomino puzzles have been around for over a century: made from 12 pieces, each piece is a different combination of 5 squares. All the pieces are put together to make a rectangle, but you can’t have any gaps or overlaps. This challenging brain-teaser has over 2000 possible solutions!
The Prime Radicals team starts you off with easier versions of the puzzle– almost complete rectangles with only a few pieces missing. Each completed puzzle adds a floor to your PentoTower. As you progress, you’ll get fewer hints. The challenge is coming up with different solutions to every level! The sky’s the limit on your Pentomino skyscraper!
In addition to PentoTower, the Pentominoes game has other challenges to test your geometry skills. PentoPuzzle gives you jigsaw-puzzle-style shapes to complete, using Pentomino pieces. These puzzles range in difficulty from those that require only 3 pieces to solve, to those that require all 12 Pentomino pieces, a radical challenge!
Prime Radicals: Pentominoes is the most fun geometry puzzle you’ll ever play. This game can provide endless hours of entertainment and fun, as you build your PentoTower higher and higher! Test your skills today!
