Screw Pop

Screw Pop is a relaxing yet clever wood-and-bolts puzzle. Colorful wooden planks are stacked on a workbench and held in place by screws. Tap a screw that isn't covered by another plank to unscrew it — it flies straight into the crate of the same color. Each crate holds three screws, and when it's full a new color takes its place. Screws that don't match any open crate wait in a small row of slots, so plan ahead: if every slot fills up and no screw fits a crate, you're out of space. Take out a plank's screws and it swings from its last bolt before dropping off the board. With 200 levels that grow from a few simple planks to crowded, tricky workbenches, there's always a new puzzle to crack. Stuck? Use a hint to light up a safe screw, or add an extra waiting slot. Earn coins and stars as you play and unlock seven wood themes, from Walnut and Cherry to Bamboo and Gold Leaf.

Tap a screw to unscrew it. Only screws that aren't covered by a plank on top can be removed. Each screw flies into the open crate of the same color; every crate holds 3 screws and is replaced by a new color when full. If no open crate matches, the screw goes to a waiting slot and moves into its crate later when that color opens. If all waiting slots fill up and no free screw fits a crate, the level is lost. Remove every screw to drop all the planks and clear the level. Use HINT to highlight a safe screw and +SLOT to add an extra waiting slot. Clear a level without boosters for 3 stars.
