Wickgrid is a grid deduction puzzle built on three rules. Numeric clues tell you how many cells to light around them. Every lit cell has to connect into a single chain. And no four lit cells may ever form a 2x2 square.
That's the whole ruleset. You'll have it in under a minute, and it still produces boards that take twenty.
Everyone gets the same board, and every board is verified by a solver to have exactly one solution reachable by logic. No guessing, ever. Difficulty climbs through the week, so Monday is a warmup and Sunday is an Extreme. Build a streak and watch the month fill in on the heatmap.
Practice mode generates unlimited boards at any difficulty. Undo a move at a time or clear the board and start fresh. Three free hints on every puzzle, and you can reveal the solution if you're truly stuck.
Send any puzzle you've solved as a link. Your friend plays the exact same board and sees your time to beat.
Free to play, with the last seven dailies always available. A single one-time unlock opens the full archive, unlimited hints, streak protection, and detailed stats. No subscription.
