How to play
A plank goes through five machines, one after another, and comes out looking like the target. Work out which five machines — and what order they run in.
The order matters. Drill a hole and then turn the plank, and you get something different from turning it first and drilling after.
You get five tries. After each one you see the plank that came out, plus a colour on every machine you picked:
Right machine, right place
Right machine, wrong place
Not used at all
Only one order of five machines makes the target — every puzzle is checked against all 7,776 possible orders first. So when all five go green, the planks match too.
