Optional game help

  1. Choose a number from the top bank and tap an empty playable cell. Numbers do not move once placed.
  2. Choose a reaction and tap the one empty cell between two numbers. If horizontal and vertical pairs meet there, both valid calculations happen together.
  3. Understand the result. The left/top tile receives the tens digit; right/bottom receives the ones digit. A zero disappears. Negative subtraction is invalid.
  4. Unlock new reactions as you advance. Levels 1–10 use + and −; ALL −1 joins at Level 11. × joins at Level 21 (after Level 20). Finish Level 30 to unlock 6 ⇄ 9 for Level 31.
  5. Clear every number to win. A full board is an immediate Game Over.
  6. No time limit. Fewer total steps and faster clears earn higher scores; Combo and DUAL REACTION only offer small, shared capped bonuses. Pause hides the puzzle and stops the timer.

Four items are always visible in each bank. Each successful use immediately refills the same slot from an unlimited deterministic sequence. Invalid moves do not consume a tile.
