Steal a Brainrot 
The Advent Calendar in Roblox’s Steal a Brainrot drops daily rewards from December 1st through Christmas, with the grand prize being an exclusive “25” Brainrot that generates $2.5 million per second in passive income. Miss a day and you’ll pay 49 Robux to recover it, which adds up fast if you skip multiple logins.
This guide covers where to find the calendar, what each day unlocks, whether the final reward justifies the grind, and how to avoid scams targeting players chasing event items.
What is the Steal a Brainrot Advent Calendar event?
The Advent Calendar in Steal a Brainrot is a daily login event running from December 1st through December 25th, 2025. Walk up to the calendar machine near the shop, click it once per day, and you’ll get a free reward ranging from Brainrots to Luck multipliers to in-game cash.
The big chase item drops on December 25th: the “25” Brainrot. This exclusive holiday Brainrot costs $600 million in-game currency and generates $2.5 million per second in passive income once you own it. If you miss a day, you’re not completely locked out. The game lets you recover any missed reward for 49 Robux per day, though that cost stacks up fast if you skip multiple logins.
Where to find the Advent Calendar in-game
The Advent Calendar sits right next to the main shop in the hub area. You’ll spot a large Christmas tree with a glowing red-and-green machine at its base. Spawn into the default location and walk toward the shop. The calendar’s festive decorations and bright colors make it hard to miss, and you can interact with it by clicking when you’re close enough.
How does the Advent Calendar work?
Click the calendar machine once per day to claim that day’s reward. The calendar resets at 12:00 AM UTC/GMT, which translates to 7:00 PM EST the previous evening or 8:00 AM in parts of Asia, depending on your time zone. Missing the daily window means you either wait for the next reset or pay 49 Robux to recover that specific day’s reward. The game tracks which days you’ve claimed and which you haven’t, so your progress carries forward even if you skip a day.
Advent Calendar rewards
The calendar offers 25 days of rewards, with each day unlocking something different.
- Rare brainrots
- Luck multipliers
- Lucky Blocks
“25” Brainrot, the exclusive Christmas reward, as seen in-game.
The Day 25 reward is the main reason most players commit to daily logins. The “25” Brainrot features a candy cane design with festive particle effects, making it one of the most visually distinct items in Steal a Brainrot.
Players who claim all 25 days also receive a bonus cosmetic badge proving they completed the full event. The badge doesn’t provide gameplay benefits, but it works as a status symbol in lobbies and serves as proof you didn’t miss a day.

Daily rewards from the Advent Calendar.
What happens if you miss a day?
Missing a day means you can’t claim that reward during the normal reset window. However, the game offers a recovery option for 49 Robux per missed day, and this remains available until December 25th, when the event ends.
If you miss five days, you’d spend 245 Robux total to catch up. For players chasing the Day 25 Brainrot, missing multiple logins turns into a real-money decision since Robux costs actual cash.
The recovery system prevents complete lockouts, but the cost adds up quickly. Setting a phone alarm or daily reminder helps avoid the Robux expense if you’re committed to getting all rewards without paying.
Is the final reward (Brainrot 25) worth it?
The “25” Brainrot generates $2.5 million per second in passive income. That’s one of the highest passive income rates available in Steal a Brainrot, making it valuable for long-term progression and currency grinding.
If you play almost daily, it’s worth it, but to play daily just to unlock the “25” is definitely not worth it. The Admin Abuse events will grant you better rare brainrots with way less effort.
Safety tips
Scammers target event hype by offering “free Robux” to recover missed days or claiming they can duplicate Advent Calendar rewards. Both are fake and designed to steal your Steal a Brainrot account credentials or payment information.
- Never share your password with anyone claiming they can help you catch up on missed days
- Don’t click suspicious links in YouTube comments, Discord DMs, or forum posts related to the event

Community insights and player experiences
Reddit threads on r/StealABrainrot show mixed reactions to the Advent Calendar. Veteran players appreciate the free rewards and see the daily login as a low-effort way to stack passive income over the month.
Most agree the event is generous compared to other Roblox games that lock similar rewards behind paywalls, though.
Common FOMO concern: Players worry about missing a single day and having to spend Robux to recover. The 49 Robux per day cost feels steep when it compounds, leading some to set phone alarms or calendar reminders to log in daily.
