Tap a piece → tap the board to test → rotate with the buttons → tap Place to confirm.

Pick a piece on the left (click), move it onto the board, click again to place. Arrow Left / Right rotates while you hold a piece. Fill a full row or column to score XP — faster is better. Four black squares roam the board and jump to new random spots after each move. Level up earns red bombs: click a bomb to arm it, then click a black square — it turns white for 1 turn only.
