Expired Brainrot Tower Defense Codes 2025

Good news – there are currently no expired codes for Brainrot Tower Defense! Every code released since the game's launch is still active. This won't last forever though, so redeem them while you can.

How to Redeem Brainrot Tower Defense Codes?

Redeeming codes takes less than 30 seconds. Here's the exact process:

1. Launch the game – Open Just Brainrot Tower Defense on Roblox
2. Click the Gear icon – Look in the top-left corner of your screen
3. Select "Codes" – This opens the redemption window
4. Enter your code – Type or paste it into the "Gift code" field
5. Hit Redeem – Your gems appear instantly in your account

Common Redemption Issues & Fixes

Code not working? Here's what to check:

• Case sensitivity – Codes must match exactly (I recommend copy-pasting)
• No extra spaces – Even one space breaks the code
• Already redeemed – Each code works once per account
• Server issues – Try switching servers if nothing works

Best Units to Summon with Your Free Gems

With 1500 free gems from codes, you can perform 30 single summons or 3 ten-pulls with 150 gems left over. Based on my testing and the current meta, here's what you should aim for:

S-Tier Priority Targets

• Saturno Saturnita (Mythic) – The ultimate boss killer with splash damage
• Graipus Medussi (Secret) – Best full AOE unit but extremely rare
• Major Combination – Game-changing slow effect for crowd control

A-Tier Alternatives

• KarKerKar KurKur (Mythic) – Excellent circle DPS, easier to obtain
• Los Metteo (Combination) – Second-best single-target damage
• Pot Hotspot (Battle Pass) – Free with premium, amazing for F2P players

Beginner-Friendly Units

• Dragon Cannelloni – Strong early game, falls off later
• Ballerina Cappucina – Great starter AOE unit
• Los Tralalero – Essential economy unit for faster upgrades

Strategic Summoning Tips

After helping dozens of players optimize their pulls, here's my proven strategy:

For New Players:

1. Use your first 450 gems on a 10-pull for guaranteed variety
2. Save remaining gems for rate-up banners
3. Focus on getting one strong DPS and one economy unit

For Veterans:

1. Wait for Mythic rate-up events (usually weekends)
2. Target specific banners when your desired unit is featured
3. Consider combination attempts if you have duplicates

• Holiday Events – Special codes during Roblox events
