How to play

Number Rain practices quick mental arithmetic. Problems with all four signs fall toward the water. Type an answer and press Enter to pop the lowest drop with that answer, or tap the number pad. You have three lives: each drop that lands costs one and lifts the water a little, and the round ends with the third. A wrong number costs nothing. Solving drops earns points, more as the numbers get bigger, and a missed drop eases the pace back a step.
