This familiar number puzzle, where you combine identical numbers on a 4x4 board, now has a new rule: "Determine direction with cards."
■ Move the board with cards
Only the cards in your hand can move the board in any direction.
You can't freely choose up, down, left, or right, so deciding "which cards to keep" is crucial to victory.
■ Replenish cards from the deck after each use
Played cards go to the discard pile. When the deck runs out, the discard pile is shuffled and returned to the deck.
Read the flow of your hand and aim for the target number within the limited number of moves.
■ Stage Mode
As you progress through the stages, the target number, the number of moves you can use, and the board's mechanics change.
Challenging stages with obstructing tiles and blocked spaces are also available.
■ Collect stars to unlock new cards
Collect stars earned by clearing stages to unlock new cards and runes. The more you play, the more possibilities open up on the board.
■ Endless Mode: Challenge Until You're Stuck
A high-score attack mode with unlimited moves, unlocked after completing certain stages.
New gimmicks are added with each wave, challenging you to see how long you can survive.
Simple rules, yet deep strategic gameplay.
