Interlace

A little logic in every direction Interlace 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 threads - Compose. 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 unhurried - No 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.
