Welcome to the Into the Backrooms TD Wiki

This wiki covers Into the Backrooms TD (Roblox Game ID 123446017566246) by the Backrooms Tower Defense group — not Backroom Tower Defense (10498602208), not [TRADE] Backrooms Tower Defense (17480843538), and not The House TD. Always verify you are in the correct experience before redeeming Codes or Trading.

Into the Backrooms TD is a Roblox tower defense set in the Backrooms — the liminal creepypasta universe of endless yellow halls and fluorescent hum. Creatures from the Backrooms invade your world, and you must summon towers to stop wave after wave of Entities. Team up with friends, unlock deeper Backrooms levels, climb leaderboards, and trade units with other players.

Our wiki exists because players face real confusion: multiple Roblox games share similar names, Codes from one title do not work in another, and Trading values shift after every balance patch. We focus exclusively on Into the Backrooms TD (Game ID 123446017566246) so every Code, Tier List entry, and walkthrough applies to the game you actually launched.

Whether you searched for active Codes, Trading values, or a Tier List, you will find verified, depth-first guides here — not recycled content from unrelated Backrooms games.

What Makes This Game Different

Unlike older Backroom Tower Defense titles, Into the Backrooms TD ships with a full Trading system in the title bar. That single feature changes how you progress: a lucky Secret pull can accelerate your account faster than weeks of grinding, but only if you understand fair values and avoid scam trades.

The summoning system emphasizes mega-rare towers — high-rarity units with abilities that redefine how you approach later Backrooms levels. Coins and Gems fuel crate openings in the lobby, while Codes and events provide bursts of free currency. The developer releases a new Code every 1000 likes, so checking our Codes hub weekly pays off.

Levels progressively introduce new Entity types, environmental hazards, and reward tables. Beating a level unlocks the next Backrooms floor, new craft materials, and sometimes exclusive units. Our All Levels guide maps every stage so you know what to prepare for before queueing.

How to Use This Wiki

Start with How to Play if you are brand new. Complete the tutorial, redeem every active Code, and read PC Controls or Mobile Controls depending on your platform.

Mid-game players should prioritize Meta Rankings and Endgame Builds before spending premium currency. If Trading is your focus, open the Trade Calculator before accepting any offer — even trusted friends can misjudge values after patches.

We update titles with the current month and year so you know pages reflect the latest Roblox meta. Bookmark the homepage and check Current Events during limited-time updates for exclusive rewards.
