In Tunnel Rush, the scoring system typically works based on the distance traveled by the player through the tunnel. As the player navigates through the tunnel, they earn points for each section or segment successfully completed. The longer the player survives and the further they progress, the higher their score will be.

Additionally, some versions of Tunnel Rush may incorporate a scoring multiplier that increases as the player progresses through the tunnel without colliding with obstacles or walls. This multiplier can boost the points earned for each section completed, rewarding players who demonstrate skill and precision in maneuvering through the tunnel.

Players can aim to achieve high scores by staying alive as long as possible, dodging obstacles, collecting power-ups, and navigating through challenging sections of the tunnel. Competing with friends or other players on leaderboards adds a competitive element to the game, encouraging players to strive for higher scores and improve their performance with each playthrough.
