Tunnel Ball takes you on a journey where you control a rolling ball deep into an obstacle-filled tunnel, requiring you to navigate through available gaps.

Tunnel Ball is played from a first-person perspective looking into the tunnel. The ball constantly moves forward while track sections and obstacles appear in succession. You must observe the surrounding space to find the right path.
The tunnel is not merely a straight passage. Shifts in perspective, obstacle layouts, and movement speed turn identifying gaps into a test of reflexes. A single wrong turn can cause the ball to crash into an obstacle, ending the game.
Dodging obstacles is a constant challenge throughout the journey in Tunnel Ball. Roadblocks force you to find the correct opening to guide the ball through safely.
Obstacles may include long blocks rotating continuously along the tunnel walls, constantly shifting positions and narrowing the path. There are also spiked blocks that suddenly rise and retract, creating extremely narrow gaps that appear only briefly. A miscalculation in timing or a split-second delay in movement can lead to an immediate collision. Instead of relying on fixed habits, observe how obstacles are arranged and move in each section.
Players must master the controls to guide the ball past obstacles within the tunnel and achieve the highest possible score.
The ball moves forward automatically, so you should focus on steering rather than managing speed through complex controls.
