The road is one glowing line down the hill and it does not stop. Hold the throttle. Tip back off the lip, hold the flip, land on both wheels and the coins come down with you. Get it wrong and the rider leaves the bike, and the hill takes it from there. The line curls into full loops. Carry the speed and the ring hands you out the far side. Come up short and it keeps what is left. Helmets take the hit. Half Shell, Full Face, Crash Cage - each one soaks up head impacts until it comes off, and after that there is nothing between your skull and the road. Today's race is one course on one bike, the same for everyone until midnight. Ride it once or ride it until you are sick of it; the best time is the one that stands. Every day you ride is kept. Past runs stay on the hill. Line up against the ghost of your own best run and watch for the place it pulls away. Coins come off every run. Spend them in the garage on the engine, the tires, the chassis and the nitro, then take the same hill again and see it get shorter. Awards for what you did out there: top speed, flip chains, loops, distance, crashes, race finishes. Plays offline.

Read full description

Slimbo is a physics puzzle about goo, gravity and gentle chaos. Drop soft jelly blocks into a stone pit and watch them squash, sag and settle. Nothing snaps to a grid — every piece leans on the ones below it, so your tower is only as good as the physics holding it up. The goal is simple: reach the lollipop. Getting there is not. • 18 handcrafted sites, each with its own trick • Soft-body jelly that stretches, tears and collapses for real • Hooks, ledges, thorns — and a hungry little bug that eats your work • A winged candy that hops away just as you close in • A hint when a site refuses to give in • No timers, no lives — think as long as you like One finger is enough. Tap to rotate, drag to drop, and let gravity do the rest.
