What is Pentomino

Pentomino is a classic geometric puzzle game that tests your ability to visualize and fit shapes together. Arrange all twelve pieces to complete the grid without leaving gaps or overlaps.

How to Play

Drag and rotate the twelve pentomino pieces to fit them perfectly into the rectangular board. The puzzle is solved when every square on the board is covered with no pieces overlapping.

Tips for Playing

  • Start by placing the largest or most awkward shapes first, as they become harder to fit later.
  • Look for symmetrical arrangements—many solutions use a mirror-image approach.
  • Try to keep a balanced mix of horizontal and vertical pieces as you build.
  • If you're stuck, temporarily remove a piece and try a different orientation.
  • Practice with smaller boards (like 5x6) before attempting the larger ones.
