Today's Puzzle

Bring the castle into 1–10 within a limited number of moves and finish it with your cards. The hand, the operations and the incoming cards are known from the start; there is exactly one way. Think, try, try again.

How to play

• The Operation strip shows each move's operation. The current one is highlighted.
• Pick 1 card: apply it to the castle (e.g. castle 40, operation +, card 5 → 45).
• Pick 2 cards: merge them with the same operation into a new Union card (e.g. 5 × 4 = 20). That also counts as a move.
• After every move the next card from the Incoming strip joins your hand; you always hold 3 cards.
• When the castle is in 1–10 and one of your cards equals it, or two cards can make it, the puzzle is solved; you never have to say "finish".
• If you run out of moves, try again: tries are free, but stars shrink (3 on the first try, 2 on the second, then 1).
