GridLock features 7 geometric piece shapes on a 10×20 grid. Arrow keys or on-screen buttons move and rotate pieces. Completing full rows clears them and scores points. Clearing multiple rows simultaneously scores exponentially more. Level advances every 8 lines, increasing fall speed. Stacking to the top costs 1 block and resets the board. Combo scoring multiplies with level.
