Lucky Blocks are the gambling layer of Steal a Brainrot. You buy a sealed brainrot for cash or Robux, open it, and roll on its drop pool. Some Lucky Blocks pay off massively — others are coin-flip traps that net you a Common when you needed a Mythic. This tier list ranks all 12 Lucky Blocks in the game by expected value, drop pool quality, and Robux-to-cash conversion ratio for April 2026.
How Lucky Blocks work
You buy a Lucky Block with cash or Robux, equip it, throw it on the ground, and after 5 seconds it cracks open with a random drop from its pool. The drop is yours — you can keep it, sell it, or trade it.
The pools differ by Lucky Block type:
- Mythic Lucky Block: drops Mythic, Legendary, or Epic brainrots
- Brainrot God Lucky Block: drops Brainrot Gods or Mythics
- Secret Lucky Block: drops Secrets or Brainrot Gods, plus rare top-tier rewards
Higher tiers have better expected drops but cost dramatically more.
Tier list ranking
S-Tier — Always buy if you have the cash
Secret Lucky Block — $750M / 2,399 Robux
Drop pool includes Secrets (Strawberry Elephant, Headless Horseman, Griffin), Brainrot Gods, and rare top-of-pool prizes like Celestial Pegasus (~0.05% chance).
Expected value: ~$1.2B in trade value. Net positive ~$450M per open.
Verdict: Always buy if you can afford it. The only Lucky Block where the drop pool exceeds the price.
A-Tier — Worth opening for fun + gains
Brainrot God Lucky Block — $25M / 399 Robux
Drops mostly Brainrot Gods (~80%) with a small chance of stepping up to Secret tier.
Expected value: ~$45M average drop. Roughly break-even at the $25M cost.
Verdict: Yes if you want a guaranteed God or trying to fill your collection. Slightly net-positive over many opens.
Admin Lucky Block (event-only)
Drops admin-themed brainrots like Sammy and the Adminbot variants. Rare drop pool, tied to Saturday Admin Abuse events.
Expected value: Variable, but the rare drops are very high in trade demand because they only appear in the event window.
Verdict: Open every one you can during the event — they only spawn rarely.
B-Tier — Mid-tier value
Mythic Lucky Block — $2.5M / 175 Robux
Drops Mythic-tier brainrots most of the time, with rare Brainrot God upgrades.
Expected value: ~$3M average. Slightly positive at $2.5M cost.
Verdict: Yes for early-game collection-building. Past Rebirth 3, the upgrade to Brainrot God Lucky Block is more efficient.
C-Tier — Open if you have spare cash
Spooky Lucky Block (Halloween, October only)
Drops Halloween-themed brainrots like Pumpkito and Spooky variants. Limited window — they expire in November.
Verdict: Open during the event for collection completion + the chance at limited-only drops, but not as a primary income source.
Festive Lucky Block (December)
Christmas-themed pool — Santa-related brainrots, Reinito Sleighito chance.
Verdict: Same logic — buy for the event, do not chase outside.
Heart Lucky Block (Valentine's, 2 weeks)
Romance-themed pool — Cupid units, La Romantic Grande chance.
Verdict: Mid-value. Worth opening 1–2 if you have spare cash but not a priority.
Leprechaun Lucky Block (St. Patrick's, 4 days)
Very limited window. Drops Irish-themed brainrots and gold-tinted variants.
Verdict: Only 4 days available — open for completion if you can.
Egg Lucky Block (Easter, 2 weeks)
Easter pool — bunnies, chocolate-themed brainrots.
Verdict: Mid-tier seasonal. Buy if you missed the egg-hunt event.
D-Tier — Skip unless you like burning cash
Los Lucky Block (Admin Abuse exclusive)
Drops "Los"-themed brainrots that combine multiple base brainrots. Cool flex but inconsistent value.
Verdict: Only open if you are at the Admin Abuse event with cash to spare.
Taco Lucky Block (Admin Abuse exclusive)
Drops taco-themed Latin variants. Trade value is event-dependent — high during the event, drops afterward.
Verdict: Trade quickly within the event window or skip.
Los Tacos Lucky Block (Admin Abuse exclusive)
Drops Los Tacoritas and other rare combinations. Very niche reward pool.
Verdict: Only for completionists.

Best Lucky Block ROI strategy
If you have $25M sitting around, the math is:
- Open 1 Brainrot God Lucky Block: 9% chance to upgrade to Secret = ~$67M EV
- Save up to $750M and open Secret Lucky Block: ~$1.2B EV ($450M net per open)
The Secret Lucky Block is the better long-term play if you can hit the cash threshold. Below that, Brainrot God Lucky Blocks are positive-EV grinds.
Should I buy Lucky Blocks with Robux?
The Robux prices versus Beli are roughly equal in efficiency:
| Lucky Block | Cash price | Robux price | Cash equivalent of Robux |
|---|---|---|---|
| Mythic | $2.5M | 175 R | ~$2.4M |
| Brainrot God | $25M | 399 R | ~$23M |
| Secret | $750M | 2,399 R | ~$700M |
Robux is slightly cheaper in pure conversion but only worth it if you are time-poor.
Frequently asked questions
Can I trade Lucky Blocks?
Some Lucky Blocks are tradable, some are not. Seasonal and Admin Abuse blocks usually cannot be traded.
Do Lucky Blocks expire?
Seasonal Lucky Blocks vanish from the shop after the event ends, but blocks already in your inventory stay forever.
Can I open Lucky Blocks during AFK?
No — opening requires you to physically throw the block, which means you must be active.
What is the rarest Lucky Block drop?
Celestial Pegasus from Secret Lucky Block, at ~0.05% drop rate. The next rarest is the Admin-only top tier.
Do Lucky Block drops apply mutations?
No — drops are always non-mutated. You can later apply mutations during events.
Final 2026 Lucky Block strategy
If you only buy one Lucky Block this month: Secret Lucky Block. The EV beats every other option. If you cannot afford $750M yet, grind Brainrot God Lucky Blocks at $25M each — they are positive-EV stepping stones that compound your cash and collection.
For seasonal blocks, prioritize Halloween's Spooky Lucky Block and Christmas's Festive Lucky Block — they have the longest event windows and the best drop pools of the seasonals.
Skip Mythic Lucky Blocks once you are past Rebirth 3. The drop pool stops scaling up to your collection level and you waste cash that should go to higher-tier blocks.
