Kids mode
202 levels on a gentler ramp, from a generator that cannot produce a dead end.
Out now on iPhone and Android
Slide everything. Group every colour.
There is nothing to pick up and no turn to plan around. You swipe, and every piece on the board moves at once — until it hits a wall, an edge or another piece. The whole game is finding the swipe that leaves each colour in one group.
Free to play, with ads and optional purchases. The solo game runs on your device, offline, with no account.
The move
Swipe left and the whole board goes left together. A wall stops whatever reaches it, so the same swipe moves every piece a different distance — and that is where the puzzle is.
One swipe left. The hatched square is a wall — it is why the blue pieces stop early.
Each level carries a par — the fewest swipes it can be done in. Solve it at all and you have solved it; match par and you get all three stars, which is a different and much harder question.
There is no timer and there are no lives. A board you cannot see is a board you can put down and come back to.
The size of it
Every number here is counted from what ships — the level data in the app, or the rows in the database the app reads. None of them is rounded up.
Ways to play
Not a grid of level numbers — one continuous path you walk, 1,020 levels long, through 51 chapters and ten regions: Shoreline, Reeds, Stonefield, Orchard, Quarry, Pinewood, Moor, Ironworks, Heights and Far Reach.
New ideas arrive one at a time, and the path remembers where you stopped.
Pick a difficulty — Quick, Normal, Hard or Extreme — and a board is dealt straight away. There are 5,221 of them, split almost evenly between the four.
The pool lives on the server rather than inside the app, so it can grow without you updating anything.
One board a day, and it is the same board for everybody who opens the game that day. That is the whole point of it: your move count only means something beside somebody else's if you both solved the same thing.
So it comes from one calendar on the server, with no local fallback, deliberately. The calendar is filled in to 2 July 2029.
Race friends live on the same boards and watch the standings move as people finish — or send a challenge instead and let them answer it whenever they like, which is the version that survives everybody being in a different timezone.
Afterwards you can put your board next to theirs and see where the moves went.
Place pieces and walls and the game's own solver checks the board as you go, so what you share always has an answer. Send it as a code, or publish it and let anybody play it.
The community list is other people's boards, and it is where yours ends up.
And also
202 levels on a gentler ramp, from a generator that cannot produce a dead end.
Limited-time sets with their own boards and their own look, on for a while and then gone.
A profile, a friend list and invites — enough to find somebody and race them.
Ladders that count what you actually do, and a few small things to aim at each day.
A picture says who you are; a frame says what you have done. Some are earned, some are bought.
Browse what other players have published and play it. Report anything that should not be there.
The unglamorous half
Switch the marks on and every colour carries a shape as well — a pawn, a rook, a knight, a bishop, a queen. The rule underneath it is that a colour may never be the only thing telling two pieces apart.
The journey, Quick Play, the builder and kids mode need no connection at all.
Sign in only if you want the daily, friends, races or the community list.
Arabic, Chinese, English, French, German, Italian, Japanese, Portuguese, Russian, Spanish and Turkish.
Six themes, one of them light, and the board is drawn to be legible in all of them.
Ask the phone for less movement and the game stops sliding things about.
Arrow keys or WASD move the board, so a swipe is not the only way in.
Free, on your phone. The download page sends you straight to your own app store — or, if you are reading this on a computer, gives you a code to point your camera at.
Android and iPhone. Ads and optional purchases; nothing to pay to start.
