Kick a rock until it's round.

A lumpy rock falls out of the sky. Kick it up the road. Every kick knocks a bit off for good, the way a real pebble wears: corners first, then edges, then the big bumps. Land the last kick and 100% ROUND hits the screen.

Spend the chips

The chips you knock off buy upgrades on a tree with six branches:

• Footwork: run faster, catch a rock that got away, kick quicker and reach further
  
• Moves: throw it, dropkick it, slide into it, call it back
  
• Boots: wear more stone off with every kick, and crits that chip at the worst bumps
  
• Economy: more chips, and new ways to earn them
  
• Road: bottles to smash, bowling pins to strike, boards to knock flat
  
• Guns: a laser sight for your kicks, then a slingshot, a hand cannon or a rifle for a rock's rough start (kicks still finish every rock)

Each branch ends in a choice of two keystones that change the rules. Refunds are free in the vault, so try a new build on every rock.

Ten worlds and a vault

Every rock you round goes into your vault, and the road carries on somewhere new: the jungle, the snow, Mars, the Moon, all the way to hell. Save up chips to open the vault's back rooms (a bowling alley, an ice rink, a stadium) where your rock is the ball.
