Bolt Box: Screw Puzzle

Colored bolts hold a pile of plates to the board. Unscrew them, sort them into boxes by color, and clear every plate. HOW IT WORKS - Tap any screw that no plate covers. - It flies to the open box of its color. Three screws fill a box and a new one arrives. - No box for that color yet? The screw waits in the tray, and jumps into its box as soon as one arrives. - Free a plate's last screw and it drops away, uncovering the screws beneath. - Fill the tray and the level is lost. Look before you tap. ENDLESS LEVELS Every level is built to be solvable. New colors, more plates and deeper stacks arrive as you climb. PLAY YOUR WAY - Easy, Normal or Hard: 6, 5 or 4 tray slots, with more points on harder settings. - Brutal: 3 slots and tougher, deeper levels for puzzle veterans. - One extra slot per try when you need a hand. - Combos for filling boxes quickly. - Online leaderboard with a nickname, no account. - English and Arabic. Free and works offline. No forced ads: watch a short video only when you want one more tray slot. Your progress is saved on your phone.
