Abstract
A polyomino piece includes a cube with six sides. Five sides of the cube each have four openings defined therein and arranged in two rows and two arrays. The remainder sixth side of the cube has two openings catercorner defined along a diagonal of the sixth side, and two first lugs catercorner formed along the other diagonal of the sixth side. A plurality of polyomino pieces can be combined to form various patterns, and the first lugs are hidden inside the patterns and cannot be seen at the outer surfaces, so that the patterns have nice appearances and can be stably placed.
