Click the red bar at the top to start. This is your timer that will count down 60 seconds.
Select as many valid period 3 or higher siteswaps from the grid as you can. The numbers don't have to be in a straight line. The higher the period the higher the score.
You receive an increasing combo bonus for each siteswap that uses the same number of props that you string together.
Select two adjacent numbers to swap them. Swapping incurs a score penalty that increases with each swap plus resets your combo bonus.
