About Parker

Parker is a free daily sliding-block puzzle from Source of Truths. A jammed six by six lot, a dozen blocks that each slide on one axis only, and a red block that has to reach the gap in the wall. Tap a block, tap where you want it, and it goes if the lane is clear.

Every board is machine generated and then solved exactly, so perfect really is the fewest moves that exist rather than somebody’s guess, and it was confirmed by a second solver written independently of the first. Par sits a cushion above perfect: it is the number a clean solve lands on, and it is beatable. Boards climb through the week, from about a dozen moves on Monday to twenty by Saturday, and the Sunday Edition runs a good deal longer than any of them.

A new board drops every day at midnight Eastern. No app, no signup, play free in your browser, keep a streak, and race the daily leaderboard. More dailies: Check, our daily checkers shot, Four, our daily Connect Four position, and Mate, our daily chess endgame.
