Build Your Backrooms Tier List

Prioritize a monster, building, or layout change only when repeated visitor tests show that it increases completed catches under comparable conditions.

Test note: Change one maze variable at a time so the result can be attributed to that choice.

Ranking note: Roblox confirms that monsters catch visitors; individual names and stats are not yet published in a reliable source.

An upgrade belongs here when its measured cash gain can repay its purchase cost in a useful time window, including offline earnings where applicable.

Test note: Compare equal observation windows and avoid buying another upgrade during the test.

Ranking note: Use Maze Lab with your own before-and-after cash samples because no official rate table has been verified.

A costly monster or building stays low-confidence until its catch or income effect beats a cheaper alternative in repeat tests.

Test note: Record cost, test duration, catches, cash gained, and maze conditions before promoting it.

Ranking note: Price, rarity, or appearance alone is not evidence of better performance.
