How to play
Each row shares one hidden rule. Each column shares another. Rules may involve meaning, spelling, sound, phrases, word relationships, or transformations. A card belongs where its row rule and column rule intersect.
Cards marked Locked stay in their squares. A wrong check tells you only how many of the six lines are correct—not which ones.
