How to Play

Discarding (Core Rule)

• You may only remove cards from the top of a column.
• Click one card then another in the same column to select a contiguous range that includes the top card.
• The selected cards are discarded only if they can be split into two adjacent groups with equal sums.

Discard Example:
Column top-to-bottom: 3, 4, 5, 2
Valid because: 3 + 4 = 5 + 2

Win: match all six columns to their targets to pick the lock 🔓
