The CoralBlox vs LukeBlox event in Be A Lucky Block pulls your rolling block into a separate realm where two of Roblox's biggest YouTubers fight over it. The side you back during a tug-of-war minigame determines which exclusive brainrots drop, and clearing both collections unlocks a limited-time base that you cannot get any other way. Here's everything you need to know to finish both indexes before the event window closes.
How does the CoralBlox vs LukeBlox event work?
The event runs on Be A Lucky Block's rotation system, so it is not always active. A board mounted above the Lucky Block road displays the current event schedule, which lets you plan your sessions around it.
When the event is live, a door flanked by dark purple flags appears along the road. There is no manual activation required. According to Pro Game Guides, every Lucky Block you roll carries a 40% chance of being pulled through that door into the rival realm where both CoralBlox and LukeBlox NPCs are waiting.

Check the schedule board above the road before each session. Rolling during the active window is the only way to trigger the event, so there is no point grinding outside of it.
How to win the tug-of-war minigame
Once your Lucky Block enters the realm, a tug-of-war minigame appears on screen. A green indicator slides back and forth across a meter that has two colored zones. Your job is to click at the right moment to side with your chosen YouTuber.
- Click when the green bar lands inside the yellow zone to side with LukeBlox
- Click when the green bar lands inside the purple zone to side with CoralBlox
- Mistimed clicks do not count toward either side
- You need 3 to 4 successful hits on the same side to win the minigame
Once you rack up enough successful clicks, the winning NPC carries your Lucky Block to their base and opens it. You then spawn as a brainrot inside that base and need to get out immediately. According to both Pro Game Guides and allthings.how, getting caught means losing the reward, so speed is the priority the moment the block opens.
Every successful escape pays out Coraluke Coins, which you spend on the Coraluke Wheel for additional brainrot pulls.
Do not linger in the base after your block opens. The escape is timed and getting caught forfeits your reward for that run.

What brainrots can you get from CoralBlox?
Coral brainrots only drop from Lucky Blocks opened by CoralBlox. Collecting all five unlocks the Secret Lucky Coral Block, which the game scales to always be 187% stronger than your best current Lucky Block.
The two rarest pulls, Pot Coralspot at 0.9% and CoralBlox at 0.1%, become more reachable when a 2x Luck event overlaps with the rotation. Allthings.how notes that the Coraluke Wheel can also drop event brainrots from either index, which helps if a specific roll keeps missing you.
What brainrots can you get from LukeBlox?
Luke brainrots come exclusively from Lucky Blocks opened by LukeBlox. The full set of five unlocks the Secret Lucky Luke Block, which also stays permanently at 187% stronger than your best Lucky Block.
Both Coral and Luke brainrots are giftable to other players. If a friend has duplicates of a brainrot you are missing, trading is a valid shortcut to finishing either index without grinding the same side repeatedly.
What is the Coraluke Base and how do you unlock it?
Completing both the CoralBlox Index and the LukeBlox Index unlocks the Coraluke Base, a limited-time reward tied specifically to this event window. This is the only progression milestone in the event that requires clearing both sides rather than committing to just one.
There is no workaround. You need all 10 event brainrots across both collections to claim it. The Coraluke Wheel can supplement your drops from either side, so spending coins on wheel spins after you clear the common tiers is a smart move for closing out the 0.9% and 0.1% slots.
