About this game
Cardboard sheets ride in on a conveyor belt. Cut squares from the corners and fold each one into the biggest open box you can before it drops into the chute. After every fold, the volume graph shows the peak where V'(x) = 0 and where your box landed.
How to play
Drag a corner square, use the slider, or press the left/right arrow keys to set the cut size x. Press FOLD or Space before the sheet reaches the chute. Volume is V = x(L-2x)(W-2x): the closer you get to the peak (or to the target volume), the more points you score. 8 levels, 3 lives, and the belt speeds up every level.
