About Backbolt: Unscrew Take Apart
A screw puzzle you solve by undoing the build.
Colored sticks lie stacked over each other, held down by screws. You can only remove a screw
whose head is visible, and every screw you remove goes to the tray at the top. Clear all the
screws of one stick and that stick drops out, emptying its slots in the tray again.
Poke around at random and the tray fills up until nothing can be removed at all.
Finishing one stick at a time is the way this puzzle is meant to be played.
WHAT IS DIFFERENT HERE
- Undo is unlimited, always. Getting stuck never means starting over.
- No lives, no energy. Take as long as you like on a board.
- The time limit can be switched off in settings if you would rather just solve the order.
- Every board shipped here was actually solved end to end before it went in.
- No colour matching rule, so colour vision differences do not get in the way.
DIFFICULTY
40 boards: 8 easy, 10 normal, 12 hard, 10 brutal.
The last board stacks 42 sticks held by 84 screws; the densest board holds 91.
CONTROLS
Just tap a screw. No dragging, no timing windows.
Tap a screw that will not come out and the screen shows you which stick is covering it.
Twelve languages, switchable inside the app at any time.
