All active SpongeBob Tower Defense codes for June 2026

Multiple gaming sites report different active sets. The most frequently cited codes come from Dexerto and Beebom, both listing these seven: GetGudKid, CHALLENGEWON, QUESTS4LIFE, BIGGUYENERGY, FOOLSGOLD, NEWBEGINNINGS2, RAINBOWMOUNTS. Dexerto also includes GetGudKid and CHALLENGEWON while Beebom adds QUESTS4LIFE, BIGGUYENERGY, FOOLSGOLD, NEWBEGINNINGS2, and RAINBOWMOUNTS. Pocket Gamer adds SeasonReworkbby, ROADTO200K, and IMMANICPRISMATIC – but those conflict with Beebom’s expired list. Fossbytes lists GetGudKid, CHALLENGEWON, NEWBEGINNINGS2, RAINBOWMOUNTS. Driffle reports an expanded set including ADMINPRED, CODECRATEWHEN, GEMGOD, MILLIONAIREGEMS, SecretCodeisSecret, Exotic2Prismatic, TRUSTMETHISISGOOD, BFFBACK4EVER, KetchupORMustard, NeedMorePets, and ServiceCrash.

The pattern: code lists diverge by source, so always test codes before relying on them.

How to use codes in Roblox SpongeBob Tower Defense

Codes are case-sensitive – a warning from Fossbytes. Enter them exactly as shown in our lists.

“Codes can expire within about one hour of release.” — Dexerto

What is the secret formula for SpongeBob Tower Defense?

Understanding the secret formula for tower upgrades

The “secret formula” is not a single code but a strategy community members use to maximize damage. The Fandom wiki explains that optimal tower combinations yield the highest DPS. Players share formulas on forums, but no official source has published a definitive one.

The implication: if you see a “secret formula” code online, it’s likely a hoax. Real secret formulas are build guides, not redeemable codes.

How to combine units for high damage output

The community recommends pairing PRISMATIC units with support towers like SpongeBob and Patrick. Specific formulas vary by patch.

“The secret formula is a player-created meta, not a developer-released code.” — SpongeBob Tower Defense Wiki

What is the rarest thing in SpongeBob Tower Defense?

Rarest units in SpongeBob Tower Defense

The PRISMATIC unit is widely considered the rarest. It is exclusive to the code crate, according to Pocket Gamer and Fossbytes. Other rare units appear only during limited events.

What this means: if you want a PRISMATIC, you must redeem a code that grants the code crate. No other method works.

How to unlock the PRISMATIC unit

Enter a code that rewards the code crate. Driffle lists Exotic2Prismatic as one such code.

What is the code crate in SpongeBob Tower Defense?

Code crate contents and exclusives

The code crate contains the PRISMATIC unit, the rarest item in the game. Driffle describes the crate as an exclusive reward for entering certain codes.

The catch: not every code gives a crate. Only specific codes like Exotic2Prismatic and BFFBACK4EVER (which awards a secret treasure chest) grant it.

How to get code crate rewards

Follow the redemption steps below, but only codes that explicitly mention “code crate” in their reward description will give you one.

How to redeem codes in SpongeBob Tower Defense?

Step-by-step code redemption guide

1. Launch Roblox and open SpongeBob Tower Defense.
2. Reach level 10 – the code redemption option is locked until then. This is confirmed by Pocket Gamer and Dexerto.
3. Click the shop button on the navigation bar.
4. Scroll to the bottom of the shop menu to find the code entry box (per the Fandom wiki).
5. Type the code exactly as shown – case-sensitive.
6. Press Enter to redeem.

“Players need to be level 10 before codes can be redeemed.” — Pocket Gamer

The pattern: all major sources agree on the level requirement and the case-sensitivity. No controversy there.

Where to enter codes in the game

Some sources say the codes button is on the left side of the navigation bar (PCGamesN), while the wiki says it’s at the bottom of the shop. Both lead to the same input field after scrolling.
