Grant right-of-way to one lane at a time — no crashes, no timeouts.↑↓←→

Weekly Top 10

Play to set a score, then submit it to the board.

Cars approach a single shared intersection continuously from all four directions.
Use the arrow keys (or WASD) to grant right-of-way to one lane at a time — only that lane may enter the intersection.
Switching to a lane while another car is still crossing causes a crash and ends the run.
Leaving a waiting car stuck too long at the stop line also ends the run — the wait timer shows as amber, then red.

Watch every lane at once, not just the active one — a car turning red while you are focused elsewhere is the most common way runs end.
Switch lanes proactively before a car reaches a critical wait, rather than reacting only once it starts flashing red.
Traffic spawns faster as your score climbs, so a rotation rhythm that works early will need to tighten up later.
When two lanes are both getting urgent, prioritize whichever has waited longer — a fresh arrival can usually wait one more cycle.
