Every shape has a place.
Turn, nest and fit chunky wooden letters into a tiny tray. Every A, T and W is a hand-cut wooden block, and every tray looks too small until suddenly it isn't.

About LETRFIT
Pick up a wooden letter. Turn it. Tuck it into the corner. Click. LETRFIT is a calm packing puzzle: drag each letter from the shelf into the tray, turn it to any angle and nest the letters into each other until every one fits. Any arrangement that fits wins.
Turn a letter by grabbing its corner, with a two-finger twist, with a double-tap or with the Rotate button. Trays come in many shapes, from squares and circles to hexagons, crosses and notched boxes, collected into Workshops along a winding map.
Every level is built from a real solution, so every puzzle can be solved. There are no lives and no game over: the clock only decides bonus stars, and a hint places one letter for you and leaves the rest to you.

Frequently asked questions
How do I play?
Drag a letter from the shelf into the tray. To turn it, grab it near a corner and swing it around, twist it with two fingers, double-tap it, or press Rotate. Letters may not overlap each other or stick out of the tray. When every letter fits, the level is solved. The first three levels show you each step.
Is it free?
Yes. LETRFIT is free to play and has no in-app purchases. Chips are earned by playing and have no real-money value.
Are there ads?
Only optional rewarded ads, when you choose to watch one, for example for a hint or to double a reward. There are no banners, no ads between levels and never an ad when the app opens. Players under 13, or whose age we don't know, get only child-safe, non-personalised ads.
I'm stuck. What do I do?
Tap Hint: it places one letter exactly where it belongs and leaves the rest to you. Hints cost Chips, or you can watch an optional ad. Every level was built from a real solution, so there is always a way. There are no lives, so you can restart as often as you like.
How do stars work?
Solving a level always gives at least one star. Solving quickly without hints earns up to three. The clock only decides bonus stars; it never ends the game.
What is the Daily Puzzle?
Every day there is one new puzzle, the same for every player. Solve it to grow your daily streak and climb today's leaderboard. A Weekly Challenge brings special trays each week.
