Nuts and Bolts

About Nuts and Bolts

Every bolt is tangled up with coloured nuts, and your job is to untangle them. Tap a bolt to lift its top nut, then tap another bolt to screw it down. A nut only fits on an empty bolt or on one with the same colour on top. Each colour wears its own shape, so nothing relies on colour alone. The first levels have two colours and plenty of room. By the end there are twelve colours and one spare bolt, and you will have to stop and think. Undo as often as you like, and ask for a hint when stuck.
