How do you play Slidesmith?
Tap a tile in the same row or column as the gap, and every tile between them slides one step toward the gap. Use those slides to build the pattern shown, anywhere on the board. Build five patterns in as few moves as you can.
What does par mean in Slidesmith?
Par is the fewest moves for each round, added up across all five. It is worked out before the run goes live and never changes. Play every round in its fewest moves and you finish on par.
Can you beat par?
Sometimes. Par plays one round at a time, so spending a move early to set up a later round can bring you in under it. Under-par lines are checked by the server and credited on the next day's route page.
Is Slidesmith free?
Yes. Every run is free to play in your browser, with no app and no account. A free account saves your best scores and your streak across devices.
How many Slidesmith puzzles are there a day?
Three: easy, medium and hard, released at midnight UTC. Easy par is usually 5 to 7 moves, medium 9 to 12, hard 12 to 15. Every past run stays playable in the archive.
Can I replay a run?
As often as you like. Only your best run counts, so a replay can only help your score.
What are the dark bars on the board?
Walls. Nothing slides through a wall, just like the edge of the board. They change every day, stay put for the whole run, and never make a round longer than it would be without them.
