Eightrun

Eightrun is a minimalist reflex game where you steer a triangle through an endless, winding octagonal tunnel, dodging obstacle patterns as the tunnel accelerates. The tunnel is marked with a grid, and each run ends if the triangle hits a filled grid cell head-on. Your score depends on how far you get.

Dodge the patterns

You move the triangle clockwise and counterclockwise as randomized obstacle patterns appear in the grid. Learning to read the patterns and react quickly takes practice; surviving longer builds muscle memory and can lead to focused runs lasting minutes.

Stages and practice

There are 8 stages, each with its own obstacle-generation patterns, tunnel speed and acceleration. Each stage has an online leaderboard where you can compare scores with your friends. Options let you reduce the intensity of the visuals or practise at a slower speed.
