Easy to Start, Hard to Put Down

1

Slide

Tap a tile in line with the gap to slide the whole line, or drag tiles with your finger. Tiles snap home with a satisfying click.

2

Beat par

Every level has a par. Finish close to it for three stars, and win enough stars to open the next grid size.

3

Keep the streak

Come back for the Daily puzzle. Solve it on consecutive days to grow your streak and climb the board.

Everything in the Box

Level Path

300 levels across 2×2, 3×3, 4×4, 5×5 and 6×6. Boards get steadily more mixed up within each size.

Twelve Pictures

Castles, rainbows, night skies and more, all painted for the game, plus plain numbered tiles.

Free Play

Any picture at any size from 2×2 to 6×6, with Easy, Medium or fully Random shuffles.

Photo Puzzles

Add a photo from your gallery or camera, then pinch, drag and rotate it into the square.

Peek, Undo, Hint

Hold Peek to see the finished picture, undo any slide, or ask for a hint that follows one sensible plan.

Leaderboards

Today's Daily (fewest moves, then time), all-time stars and live streaks, plus the world best on every level.

Frames to Earn

Pick an avatar and show off frames earned by playing: stars, a 7-day streak, 30 Dailies and more.

Sync Across Phones

Sign in with Google to keep your stars and Daily results on every phone you play on.

Feels Like a Toy

Plastic clicks, gentle haptics and a little orchestra, all switchable. Numbers on tiles and a hidden timer for little ones.

Pro Tips

•Solve the top row first, then the left column, and the rest of the board gets smaller each time.
•Slide a whole line in one tap: it counts as one move per tile, but saves a lot of tapping.
•Hold Peek to check where a tile belongs without losing your place.
•Stuck on a big board? Hints follow one plan, so keep tapping Hint and the board solves itself step by step.
•Turn on Numbers on tiles in Settings if a picture has lots of sky that all looks the same.
•Playing with a child? Hide the moves and timer in Settings and just enjoy the picture.

Questions

How do I play?

Tap a tile in line with the gap and the whole line slides over. You can also drag tiles with your finger. Put every tile back in place to finish the picture, in as few moves as you can.

Is Slidaroo free?

Yes. Every level, picture and the Daily puzzle are free. The free version shows the occasional full-screen ad between levels and gives you 3 hints a day, with a short video earning more. A one-time Premium purchase removes those ads and the hint limit.

Do I need an account?

No. Everything works without signing in. Signing in with Google is optional: it keeps your stars and Daily results in sync across phones and puts you on the leaderboards.

Can I use my own photos?

Yes. Pick a photo from your gallery or take one, then pinch, drag and rotate it into the square. Your photos stay on your phone and are never uploaded.

What is the Daily puzzle?

One 4×4 puzzle a day, the same for everyone, with a new one at midnight UTC. Solve it on consecutive days to build a streak, and compare your moves and time on today's leaderboard.

How do stars work?

Each level has a par: the number of moves a good solve takes. Finish close to par for three stars. Win 90% of the stars in one grid size to open the next.

Does it work offline?

Yes. Levels, free play and your own pictures work without internet. The Daily puzzle's leaderboard, syncing and ads need a connection.

Is there an iPhone version?

Not yet. Slidaroo is coming to Android first, on Google Play.
