At the Frostmere ice-carousel fair the village children are out riding round ice carousels on the frozen lake at sunset. Bring every one home.
Drag a carousel to turn it one step. The carousel you turn goes your way, and every other carousel turns one step the other way, all at once.
A child carried onto a little plank bridge crosses it to the next carousel, if the far end is free. Two children at the two ends of one bridge both stay.
A child carried next to an empty hut of their family's colour hops off and goes in for cocoa. Each hut takes one child.
Bring every child home in the fewest turns for three stars. Undo and Restart are always free.
Later: drawbridges, huts with red lanterns, small carousels that hold two, and five carousels at once.
