Gear Train
All gamesOrder: the hand must turn 3 times per crank turn, clockwise. The rail is bare, so there is no hand to read. 1 gear in the train, counting the crank. 9 spanner turns left. Cursor on box gear 1 of 6, 24 teeth, spare — too big for bay 1, which takes 16 teeth.
The order
The hand must turn 3 turns for one turn of the crank, clockwise.
Crank 48teeth ÷ last gear's teeth = turns of the hand. Every mesh reverses, so an odd number of gears (the crank counts) turns clockwise and an even number turns anticlockwise.

48 ÷ (teeth on the last gear) has to come to 3 — that names the gear the hand must ride. Clockwise means an odd train, so an even number of gears on the rail.
