The blocks gradually shrink and leave the light at the end of the tunnel.

In 15% of cases stripes appear instead of blocks. 25% chance that the tunnel will be one and in the center of the screen, in other cases - several tunnels next to each other. When there are several tunnels, they are offset. There is a 33% chance that they will be rotated by a random angle.

See variations please
