Into the Backrooms TD Summon Guide

Crate Types

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.

Summoning happens in the lobby crate area on Game ID 123446017566246. Normal Crates cost Coins from level clears and Codes. Lucky Crates cost Gems with improved high-rarity rates. Gem Crates and SCP Crates offer premium pools during events.

Each crate opening rolls one unit from its pool. Duplicates are common — plan for Trading or future craft use rather than frustration when your fifth Survivor appears.

• Normal Crate — Coin cost, standard rates
• Lucky Crate — Gem cost, boosted rarity
• Gem Crate — Premium Gem pool
• SCP Crate — Event-limited pool

Gem and Coin Strategy

Redeem every active Code before buying crates. thanks1 and similar Codes fund eight Normal Crate pulls — enough for early roster building without touching Gems.

Save Gems until you have 50+ for bulk Lucky Crate sessions rather than single pulls. Bulk openings reduce variance and match strategies in our crate strategy guide.

VIP luck gamepasses stack drop rates for high-rarity units. Free-to-play players compensate with volume — more Codes, AFK gold, and level farming.

When to Stop Summoning

Stop pulling when you have a balanced six-unit team covering DPS, AoE, and debuff roles — not when you "almost" get a Secret. Chasing one unit drains resources needed for upgrades on units you already own.

Check Meta Rankings before summoning for a specific name. Sometimes upgrading Entity 67 beats gambling for Frowner at 500+ Gem spend.

Weekend 2x drop events are better for material farming than crate spam. Split time between summoning and clearing levels for dual income streams.

Pity and Statistical Expectations

Community reports suggest soft pity on high pull counts in Into the Backrooms TD, though developers have not published official percentages for Game ID 123446017566246. Treat pity as unconfirmed bonus rather than guaranteed timing — bulk openings still outperform single pulls statistically regardless of pity existence.

Rough community estimates suggest budgeting 100+ Normal Crates for Legendary odds or 20+ Lucky Crates for targeted high-rarity sessions. Variance is extreme — some accounts pull Entity 67 (150 trade value) within ten crates; others exceed 200 before first Legendary. Rare Towers guide video demonstrates bulk statistical approach.

VIP luck gamepasses and weekend event multipliers stack with crate type selection. F2P players compensate through volume: Code coin income, AFK lobby gold, and Class 2 farming fund more Normal Crates than premium Gem sessions — patience beats single Lucky pulls.

Event and SCP Crate Timing

SCP Crates appear during SCP-themed events with entity-key style exclusive pools unavailable in standard summon rotation. Open SCP Crates during active banners rather than hoarding tokens across expired events — exclusive units gain whale-tier Trading value post-event when supply caps.

Gem Crates offer premium pools worth saving 50+ Gems for bulk sessions during boosted rate windows. Outside events, Lucky Crates remain the standard Gem spend target for Legendary hunting before chasing Secret exclusives like Mega Rare Tower.

Normal Crates between events consume coin dumps from level farming and Code redemption without touching premium Gems. Day 1–3 accounts should open Normal Crates exclusively per crate opening strategy before first Lucky session.
