Interlace

A little logic in every directionInterlace is a collection of quiet puzzles that share one idea: make sense across, match colors down. Every board is a small grid of tiles. Swap tiles within a row until each row reads true, and each column holds exactly the colors shown above it. The two rules pull against each other, and that is the puzzle: one choice is interlaced with another.

Three threadsCompose. Rearrange letters into words. Every letter belongs to a color, so later puzzles hide letters and let the colors tell you what they must be. Balance. Arrange numbers into true equations. Trade plus, minus, times and divide signs between rows, and fill in missing digits. Link. Join shape tiles end to end into chains, where each tile's right-hand shape matches the left-hand shape of the next.

Made to be unhurriedNo timer. Take as long as you like. Taught by doing: the first boards show you the move instead of explaining it. Stuck? A nudge points the way, and a second tap shows a move. Any arrangement that satisfies the rules wins, not only the one the puzzle was built from.
