About this game

Build ramps so trucks can cross the gaps. Use the rise and run on the grid and a² + b² = c² to work out exactly how long each ramp must be. Too short and the truck falls in, too long and the ramp won't fit.

How to play

Read the rise and run for the gap, then work out the ramp length with a² + b² = c². Type it on the keypad (or keyboard, with arrow keys to nudge by 0.1) and press Build. When every span is built, the truck drives across. Round to the nearest tenth when needed. Later levels have bridges with two or three spans, towers where you find the missing side, and ramps that go up and down. You have 3 trucks, and you get one back each time you clear a level.
