Nuts Stack Sort: Nuts & Bolts

The goal is to clear all the colored bolts from your board. Do this by matching 3 of the same bolts onto the colored pins at the top that are first in the line. The catch is that you can’t always select the right bolts right after each other. So you have 5 temporary pins where you can put other bolts. But you can’t put more than 5 there, so be careful to put the right ones there. They will automatically be removed when the right colored pins appear at the top.
