Make 10s -keep your mind sharp

A simple arithmetic puzzle with real depth. Pick one tile from each of four lanes — four numbers in total — then choose three operators (+ − × ÷) to build an equation (× and ÷ are calculated first). Hit exactly 10 and the tiles vanish, with new ones dropping in right away. It's game over if the stack reaches the red line. Clear tiles back-to-back to chain combos and push your score higher.
