Grid Lock - Traffic Management

Grid Lock puts you in charge of a busy intersection. Cars keep coming. Your job is to open and close lanes so traffic clears without crashes or backups.

Tap a lane to toggle its gate. Green lets cars through; red holds them. Clear the intersection at the right moments, watch for overflow, and don’t let opposing traffic collide.

Campaign
Work through 30 levels with rising pressure: clear car targets, timed challenges, stuck lights, auto-cycling lanes, emergency vehicles, bad drivers, and more. Each puzzle teaches a new way the intersection can fight back.

Endless Mode
Survive as long as you can while speed and density ramp up. Pick Easy, Medium, or Hard, then mix optional hazards: emergency vehicles, stuck lights, bad drivers, tap limits, and more. Chase your high score.

Simple to learn, hard to master
One-tap controls. Real tension when lanes back up. One wrong open gate and it’s gridlock, or a crash.

Can you keep the city moving?
