About

Tunnel Flow

Features
Read full description

Arrange the vehicles. Align the tunnel orders. Ensure each action is significant. In Tunnel Flow, vibrant vehicles queue on narrow streets. Every tunnel requires a designated color and quantity of vehicles. Shift groups across roads, position the correct vehicles at the tunnel entrance, and allow each car to pass through to complete the level. HOLD, DRAG, STRATEGIZE Press and hold a car to choose it along with all subsequent cars. Move the entire group to a different path: it needs to align, and the vehicles maintain their sequence. Consider the future—each action can create a route or obstruct it. ADJUSTING ORDER MATCHES Arrange a sufficient number of vehicles in the desired color at a tunnel to fulfill its order. The dispatched vehicles vanish, a fresh order emerges, and ready cars can initiate additional deliveries automatically without requiring extra actions. UNIQUE PUZZLE MECHANICS Navigate through vehicles of uncertain colors while finishing deliveries to access new routes. Clear a road with a spawner to welcome its upcoming set of vehicles. Navigate through restricted capacity and a small number of moves while discovering the correct order. Can you provide each vehicle before your move end?
