THE NOTEBOOK RULES

Avoid the pull.

  1. Take turns choosing any empty circle. Your next number is placed automatically, starting at 1 and counting up.
  2. When everyone has used all their numbers, the last empty circle becomes the black hole.
  3. Add up your own numbers joined to the black hole by a line. There are up to six neighbors: left, right, and the four diagonals.
  4. The lowest total wins. Equal lowest totals share the win.

Play solo against the computer on the original 6-row board, share one device with friends, or invite friends with a room link. Take your time: there is no turn timer. The first player rotates on each rematch.
