On the Subject of Red Levers

8 decisions, and any can be your last.
Wait, what do you mean that’s taken?

This module has 8 small levers on it.
If the first lever is not red, you are looking at a different module.

To disarm the module, flip all 8 levers in the correct order.

The Remaining Levers

If there is a lit BOB indicator on the bomb and more than 4 batteries, flip all remaining levers in order from left to right.

Otherwise, if the first lever has not been flipped yet, flip the first lever, then the rest in order from right to left.

Otherwise, if all levers flipped so far have unique colours, flip the second unflipped lever from the right, then flip the rest in order from left to right.

Otherwise, if no Red levers have been flipped, flip the first unflipped lever from the left, then flip the rest in order from right to left.

Otherwise, flip the remaining levers in order from right to left.
