Swapple

A grid pattern must be transformed into a target pattern by swapping whole rows and columns, a puzzle based on reversible circuit synthesis. The game reports whether a shorter sequence exists, so the aim is the minimum number of moves. One pattern is set each day, and results can be shared.
