Draw line of sequence numbers the way they match values of target points, creating long and colorful strings of numbers. Sometimes, there are more than one colored number to start at and end at - so you will need to plan out your route. If the initial value is greater than one, the sequence goes in reverse order, forcing you to think backwards. Tracks can cross at same number, sharing the number in their lines.
