How to play
- 01Drag across the board to draw one straight cut. It runs from edge to edge.
- 02Each piece belongs to the side its center is on. Bigger pieces weigh more: small 1, medium 2, large 3. Sleeping, outlined pieces don't count.
- 03The pieces drift and bounce off the walls, so the perfect cut keeps moving. Pick your moment before the clock runs out.
- 04Get within 95% of the best balance possible at that moment to clear the level.
- 05Every two levels the crowd grows by two pieces, up to 100, and the pieces get smaller.
- 06You have three lives. A miss or a timeout costs one and gives you a fresh board at the same level.
- 07Reach level 21, 41, 61 or 81 and future runs can start there.
- 08On a keyboard: the arrow keys turn and move the cut, and Enter makes it.

About
Perfect Split is a precision puzzle about judging weight and space at a glance, against the clock and a crowd that won't stand still. Every level is generated fresh, so no two runs are the same.
Early levels are about counting. By the time the crowd reaches 50 or 100 pieces you can't count in time, so it becomes about seeing where the middle of the crowd is.
Tips
- > Count weight, not pieces: two small pieces balance one medium piece.
- > In big crowds, stop counting. Find the line that halves the crowd by eye, then adjust for the big pieces.
- > Watch the pieces near your line: they are the ones about to change the balance.
- > Cut just after a piece crosses into the lighter side, not just before.
- > Angles are free. A diagonal cut often works where straight ones can't.
FAQ
Is there always a perfect split?
Every board starts with one. Once pieces move, a perfect cut isn't possible at every instant, so each cut is scored against the best cut there was at that moment. Matching it counts as perfect, and after a miss that cut is shown.
What about a piece the line runs through?
It counts for the side its center is on.
What counts as clearing a level?
A cut within 95% of the best balance possible at that moment. On small boards that means a perfect cut; in a crowd of 100 you can be a piece or two off.
Is it free?
Yes. Every level is free to play in your browser, with no account and nothing to download.
Can I play on a phone?
Yes. Drag with one finger; the board fills the screen while you play.
