Katamino Pocket

Katamino Pocket is the portable, travel-ready edition of the classic pentomino puzzle game. It contains twelve different pieces, each made of five squares (like Tetris pieces, but with five squares instead of four), plus smaller filler pieces — all housed in a compact magnetic case so the pieces stay put on the go.

A movable divider lets you take anywhere from a few pieces up to the full set and fit them into a 5×N rectangle, with hundreds of puzzles of progressive difficulty. There’s also a two-player strategy mode: take turns placing pieces on the board, and the first player who can’t place a piece loses (similar to Blokus).
