Those are preconditions to join his team.

1- Learn numbers order (the order of the numbers on wheel): clockwise --> 0, 32, 15, 19, 4, 21.... and anticlockwise --> 0, 26, 3, 35, 12, 28...

2- learn calculating distances between any 2 number: if the previous spin was 32 and the current 21, then distance between them is 4 positions. If the previous spin was 4 and current 35, the distance is 7.
