Tunnel Online is a challenging 3D reaction game in which you have to swerve to avoid dropping through the holes in the walls of the tunnel. The challenging part is that the tunnel is still being built while you’re already on your way through! Look ahead, where new segments are being added to the tunnel, and spot the gaps left by the missing tiles. Skip to the left or right to collect the white pips and dodge the holes in the road. How far will you be able to travel through this awesome rainbow-gradient tunnel that keeps changing color? The amount of pips you collect determines your final score.
