Arc Turn: Rotate Tile Puzzle

Arc Turn is a rotate puzzle where you are shown the answer first.

Every picture is built from quarter circles. Two side by side make a half,
four make a whole. The picture appears complete, you get a moment to read
it, and then the pieces turn away one by one while you watch.

Now put it back. Tap a piece that looks turned around, then turn it left or
right until it fits. Nothing is ever lost - turning the other way puts it
right back.

Here is the part that makes it a puzzle: you have a limited number of
turns. Enough to solve it, not enough to try everything. Turn the wrong
piece twice and you have spent a move you needed.

WHAT YOU GET

- 246 levels, every one a different picture. No level repeats.
- Digits, letters and abstract figures, all drawn from the same quarter
circles.
- Level 1 has four pieces with three of them turned. By level 60 the whole
picture is scrambled.
- A hint that points at the piece to turn - it never turns it for you.
- Restart any level, any time, from the same board.
- A daily puzzle, the same board for everyone, a new one every day.
- Free. No purchases.

WHY IT IS NOT A MEMORY GAME

You are shown the picture, so it would be easy to assume you have to
memorise it. You do not. The shapes are things you already know - a digit,
a letter, a solid rounded blob - so a piece that is turned around looks
wrong even an hour later. What you are reading is the shape, not your
memory of it.

That is also why the pieces are quarter circles and nothing else. A quarter
disc has one rounded corner, so a wrong turn puts that corner where a
straight edge belongs. You see the error as a notch, not as a difference
from something you are trying to recall.

ABOUT THE TURN LIMIT

Most rotate puzzles are endless. This one is not, and that is the point.

Without a limit there is no reason to look before you tap - you can turn
everything four times and the picture assembles itself. The limit is what
makes the first look worth taking. It is generous early and tightens as you
go, and it is always measured against the shortest solution of that exact
board, never a round number.

Run out and you lose the level - but the game puts the picture back
together in front of you before it says so, so you always find out what you
were building.

BUILT FOR PHONES

One thumb. Tap a piece, then two big buttons at the bottom turn it. Nothing
happens between choosing and turning, so nothing happens by accident.
