Canyon is an arcade racer that consist of tracks that are somewhere between 20-30 seconds. You meet up online (or you can play against yourself) and everyone competes for the best time on each track. It's all about nailing those perfect drifts and jumps so you can shave milliseconds of your time. You can instantly restart at the push of a button.
It's a very simple premise, but it's is insanely addicting. Tracks are short and easy to learn, but difficult to master. You need to cut each turn perfectly to win against other people online.
You'll be saying to yourself: "Just 5 more minutes, I'll quit after the next track." And two hours later you're still playing. Highly recommended.
