Build Your Backrooms Maze Lab

How to get useful results

Measure several catch intervals in the same maze, then use an average instead of your best run. For upgrades, compare the income before and after one controlled change. Small, repeatable tests produce better decisions than guessed rates.

What this calculator cannot know

Build Your Backrooms can change through updates, and the game does not publish every formula. The Maze Lab calculates only the values you enter. Verify caps, rates, and upgrade effects in your current server before spending.
