About this game

Deep Sum is an underwater mental-math game where numbered bubbles drift up from the deep and you tap the ones that add up to the target sum to pop them. Overshoot the target and your selection clears, and every bubble that escapes the surface drains your air meter. Keep matching to climb levels as the numbers grow larger and the bubbles rise faster.
