Sum Stack

Shoot blocks, merge sums, chain-clear for massive points.

How to play

  • Shoot: Position a number block and fire it upward
  • Merge: Adjacent blocks that add up to the target (starts at 10) combine
  • Level up: Create enough merges and the target increases
  • Clear 4+: Connected target-number blocks disappear for 10 pts each
  • Bonus: 5+ connected = extra bonus points
  • Super (7+): Wipes the entire board + huge bonus!
  • Game over: When blocks reach the red danger zone
