How to play

  • Select a number card, then place it in any glowing open lane.
  • Single lanes add to one vault; seam lanes add the full card value to both neighboring vaults.
  • Reach each target exactly; when a vault seals, every lane touching it locks.
  • Keep unplayed cards and plan around two upcoming cards to finish all three vaults.

Controls

  • 1–5 select cards; Q/W/E/R/T place the selected card in a lane.
  • Click cards and lanes, or drag cards onto lanes.
  • Tap cards and lanes, or drag cards onto lanes.
