At its core, a is a geometric shape composed of four equal squares connected at their edges. While there are technically five "free" tetrominoes, the game uses seven distinct variations (often referred to as the I, J, L, O, S, T, and Z pieces) when factoring in rotations and reflections. Symmetry Characteristics Straight (I) Vertical and horizontal reflection; two-fold rotation. Square (O) Reflection across all axes; four-fold rotation. T-Shape Vertical reflection symmetry only. L / J Shapes No inherent symmetry; mirrors of each other. S / Z Shapes Two-fold rotational symmetry only. Key Features of the eChalk Version echalk tetrominoes
