Vaultbreaker: Solve Light Routes Before Security Breaches
Vaultbreaker is an endless heist run built from timed light-routing floors. Select a tile, activate it again to rotate, and power every receiver before the security meter empties. A breach removes one of three shields; solving banks score and descends to a harder floor. The correct objective is not frantic rotation—it is reducing uncertain tiles quickly.

Start at the receivers
Find every receiver and ask which side its final beam must enter. Trace one tile backward from each receiver and mark the orientations that could supply it. This converts the board from a large search into several local constraints.
If two receivers share an upstream junction, solve that junction before rotating distant tiles. Shared dependencies explain more of the board and reduce duplicate work.
Separate confirmed and experimental tiles
Once a segment visibly carries light in the required direction, leave it fixed while testing the next unknown. Rotating confirmed tiles destroys evidence and makes it impossible to know which change broke the route.
Use the selected-tile highlight as a working cursor. Move systematically along one branch instead of jumping between visually interesting pieces.
Budget security time by uncertainty
The security meter is a decision budget. Spend early seconds reading sources, receivers and junctions; that investment prevents repeated random rotations later. When the meter becomes low, work on the branch closest to completion rather than beginning a new theory.
A breach resets the timer but costs a shield. Treat the fresh meter as a new analysis phase, not permission to repeat the same sequence. Identify which assumption failed before rotating again.
Prefer reversible tests
A useful test changes one tile and has an observable outcome: a beam reaches a new segment, a receiver lights, or a branch goes dark. If nothing changes, return the tile and test the next orientation.
Rotating several tiles in a burst can accidentally solve a floor, but it cannot teach a method for deeper layouts. Controlled tests become more valuable as the tower adds complexity.
Review depth, not only score
The results screen records score and depth. Depth shows how many complete puzzles your method survived, while score can also reward remaining time. Use both: a fast shallow run and a slower deep run reveal different weaknesses.
After a run, recall the first floor where random rotation replaced tracing. On the next attempt, slow down specifically at that transition. Protecting one shield often matters more than saving a few seconds.
