Grand Circuit is a browser game built for short, satisfying sessions - it loads instantly, plays with one thumb, and runs on any mid-range phone. The setup is simple: 5 traffic lanes starting at 280 px/s. Nothing to install, no account, no waiting.
Traffic scrolls down 5 lanes and never stops; you weave between cars, and the closer the pass, the bigger the near-miss bonus. Coins appear in risky places - exactly where you would rather not be - and the speed climbs the whole time.
Nothing here needs a tutorial or a wiki. Controls are one gesture, the goal is one sentence, and the difficulty comes from execution rather than homework. That is exactly what a browser game should be.
