The CoralBlox vs LukeBlox event in Be A Lucky Block sends your rolling block into a side realm where two YouTuber-themed NPCs fight to claim it. Whichever side you back during the tug-of-war minigame decides which exclusive brainrots drop, and finishing both collections unlocks a limited-time base.
How the event triggers
The CoralBlox vs LukeBlox event runs on the game's rotation, so it isn't always live. Check the schedule board mounted above the Lucky Block road to see when it cycles in.
While active, a door flanked by dark purple flags appears along the road. There's no manual activation. Every Lucky Block you roll has a 40% chance of being pulled through that door into the rival realm.
Winning the tug-of-war minigame
Once your block enters the realm, CoralBlox and LukeBlox start a tug-of-war over it. A bar appears on screen with a moving green indicator and two colored zones.
Step 1: Watch the green bar as it slides across the meter. Decide which YouTuber you want to side with before clicking, since each one drops a different set of brainrots.
Step 2: Click when the green bar lands inside the yellow zone for LukeBlox, or the purple zone for CoralBlox. Mistimed clicks won't count toward your chosen side.
Step 3: Repeat until you've landed three to four successful hits on the same side. The winning NPC then carries your Lucky Block back to their base and opens it.
Step 4: After the block opens, you spawn as a brainrot inside that base. Run for the exit immediately. Getting caught means losing the reward, so escape speed matters.
Each successful escape also pays out Coraluke Coins, which you spend on the Coraluke Wheel for extra brainrot pulls.
Coral brainrots and drop rates
Coral brainrots drop only from Lucky Blocks opened by CoralBlox. Completing the full set of five unlocks the Secret Lucky Coral Block, which scales to 187% stronger than your strongest current Lucky Block.
| Brainrot | Drop chance |
|---|---|
| Pipi Coralto | 55% |
| Coralteo | 40% |
| Coraltuginni Dragonbloxinni | 4% |
| Pot Coralspot | 0.9% |
| CoralBlox | 0.1% |
Rare pulls like Pot Coralspot and CoralBlox become more reachable while a 2x Luck event is running alongside the rotation.
Luke brainrots and drop rates
Luke brainrots come from Lucky Blocks opened by LukeBlox. Collecting all five grants the Secret Lucky Luke Block, which also stays at 187% stronger than your best Lucky Block.
| Brainrot | Drop chance |
|---|---|
| Lukethinni Sushinni | 55% |
| Spioniro Lukebiro | 40% |
| Lu Lu Luke Sahur | 4% |
| Luketi Tualetti | 0.9% |
| LukeBlox | 0.1% |
The Coraluke Wheel can also drop event brainrots from either index, which helps if a specific roll keeps avoiding you.
Final reward: The Coraluke Base
Filling out both the CoralBlox Index and the LukeBlox Index together unlocks the Coraluke Base, a limited-time reward tied to this event window. It's the only piece of progression that requires committing to both sides rather than picking a favorite.
Practical pacing
Since the door only appears during the active event window and triggers on a 40% per-roll chance, throughput matters more than precision. Roll consistently while the rotation is up, alternate sides once you've cleared the common drops, and save Coraluke Coins for wheel spins targeting the 0.9% and 0.1% tiers.
If a 2x Luck event overlaps with the rotation, prioritize rolling during that window for the best shot at CoralBlox and LukeBlox themselves, the two rarest pulls in the event.
