Signalbrook

Signalbrook is a top-down traffic light game. Vehicles arrive from all sides of a little town; you decide which direction gets the green at each junction. Get the required number of vehicles through to clear a level.

Waiting drivers honk and fill the anger meter. Leave one fuming at the front of a queue for too long and it runs the red light straight into cross traffic. A crash or a full meter ends the run.

• Ten levels: from one quiet junction to three busy ones with rush hours, buses and ambulances.
• Red-light runners: a ring around a waiting car shows its patience running out; ignore it and it goes anyway.
• Buses and ambulances: buses are long and slow to pull away and count double; an ambulance kept waiting sends the anger meter soaring.
• Green waves: on the multi-junction levels the main road passes several lights, and drivers will not block a junction they cannot clear.
• Stars and unlocks: each level gives up to three stars for keeping the town calm; your progress is saved.
• Keyboard, mouse or touch: number keys, Tab and Space, or tap the junctions.
