Four Shapes

The puzzle game of one undo.

Drag a shape and it moves along the line you draw. It picks
up every shape of its own kind that it passes, and gets
bigger as it goes. Put it in the dock that matches it. Clear
the board and the level is done.

Then the rule bites: inside a single row, you only get one
direction. Go left, and left is all that row will ever give
you.

And you get one undo. One per level — not one per mistake.
After that, the only way back is to start the board again.

164 levels across four chapters.

EASY — learning what a move costs
MIDDLE — order starts to matter
HARD — every move is forced
GAUNTLET — long boards, no slack, no second chances

Every level carries a BEST: the fewest moves it can be solved
in. That number isn't a guess. Whether you find it is a different question.

What it doesn't do:

No ads. None — not between levels, not anywhere.
No account. No sign-in, no email, nothing to create.
Nothing collected, stored or sent. Works in airplane mode.
No energy meters, no daily streaks, no countdown hurrying
you along. There is a clock, but it's there to look at
afterwards, not to beat.

Nothing competes with the board for your attention. That is
the point.

The first chapter is free, and so are the first three levels
of every chapter after it — enough to feel a gauntlet board
before you decide. One purchase unlocks everything.
