Here’s one for you that I couldn’t put in the puzzle book because the solution requires more than 6 crossovers (or at least I think it does, anyway).
(You can’t tell from the picture, but all four of those bits may start pointed left or right.)
Objective: If any of the bits start pointed right, intercept a blue ball. Otherwise, intercept a red ball.
You may use any parts you like.
Good luck!
