Eight classic boards from 6×6 to 9×9 with 3 to 9 threads — the next step after the Warm-up.

Most of each puzzle still solves itself with forced moves. Then you reach a spot where a thread has two options, and you need to check where each one leads: one of them leaves an empty cell that nothing can reach, or cuts another pair off from its partner. Spot that, and the board opens up again.

The skill this set trains is seeing dead ends before you draw them. Read how to avoid empty pockets and forced moves if a level stalls. Rules: How to play.
