Half measures only.
Pieces drift down the screen. Swipe through each one and Halves weighs the two sides to a tenth of a percent. Land 50.0 / 50.0 for a Perfect. Miss by a few percent and a dashed line shows where you should have cut.
Three blades and six stages, each a little harder. Squares give way to triangles, offcuts and slivers.
Sixty seconds on the clock. Every Perfect cut buys another second.
Cut each piece to the split it shows: 40:60, thirds, quarters, fifths.
No blades to lose. Watch the sun go down and cut at your own pace.
Thirty pieces in three rounds, the same for everyone in the world. One scored run a day, then share your result.
