Lucky Blocks in Steal a Brainrot are loot boxes that trade guaranteed income for a roll at rarer, higher-earning Brainrots. Each one sits in your base as a physical block; when you open it, the game spins through a fixed pool and awards exactly one Brainrot from that list.
Rarer units almost always earn more money per second, but their drop chances are much lower. That simple tradeoff drives how valuable each block really is.
How Lucky Blocks work
Every Lucky Block follows the same basic rules:
- You buy it from the red conveyor belt with Cash, from the Robux shop, steal it from another player’s base, or get it during Admin Abuse events.
- The block sits in your base with a countdown timer. When the timer reaches zero and changes to “READY”, you can open it.
- On PC, you hold the
Ekey near the block; on mobile, you hold on the screen. - The block disappears, a roulette animation plays, and you receive one random Brainrot from that block’s pool.
Most Lucky Blocks require a short wait before opening. Event-style blocks such as Admin Lucky Block, Taco Lucky Block, Los Lucky Blocks, and Los Taco Blocks open instantly, which matters in public servers where people try to steal anything that isn’t locked.
Lucky Blocks themselves never generate income. Only the Brainrot you pull will start earning Cash once it appears at your base.
Availability and Robux restrictions
There are currently eight Lucky Blocks in Steal a Brainrot:
- Mythic Lucky Block
- Brainrot God Lucky Block
- Secret Lucky Block
- Admin Lucky Block
- Taco Lucky Block
- Los Lucky Blocks
- Spooky Lucky Block
- Los Taco Blocks
Only three are sold for Robux in the in-game Robux Shop:
- Mythic Lucky Block
- Brainrot God Lucky Block
- Secret Lucky Block
In several regions, Robux purchases of Lucky Blocks are disabled entirely due to local rules around loot boxes. In those countries, you can still buy blocks with normal Cash when they appear on the conveyor, or steal them from other players.
Mythic Lucky Block: early-game gamble
The Mythic Lucky Block is the entry-level option and the cheapest way to start rolling Mythic-rarity Brainrots.
| Property | Value |
|---|---|
| Cash cost (conveyor) | $2,500,000 |
| Robux cost (shop) | 175 Robux |
| Rarity | Mythic |
| Appearance | Red cube with white question marks, corners, mouth, and two white wings |
| In-game status | Always obtainable |
It contains five Mythic Brainrots:
| Brainrot | Drop chance |
|---|---|
| Spioniro Golubiro | 37% |
| Tigrilini Watermelini | 30% |
| Zibra Zubra Zibralini | 20% |
| Carrotini Brainini | 10% |
| Bananito Bandito | 3% |
The top-end pull here is Bananito Bandito at just 3%. For most players pushing through early rebirths, this block is the first serious shot at high-earning Mythics without relying on fusing or Admin events.
Brainrot God Lucky Block: mid-game power spike
Brainrot God Lucky Block is the blue, rainbow-trimmed block aimed squarely at players who can already afford eight-figure purchases.
| Property | Value |
|---|---|
| Cash cost (conveyor) | $15,000,000 |
| Robux cost (shop) | 599 Robux |
| Rarity | Brainrot God |
| Appearance | Blue cube with rainbow question marks, corners, and smile, plus white wings |
| In-game status | Always obtainable |
It always rolls one of these five Brainrots:
| Brainrot | Drop chance | Income rate |
|---|---|---|
| Tigroligre Frutonni | 54% | $60,000/s |
| Orcalero Orcala | 30% | $100,000/s |
| Bulbito Bandito Traktorito | 10% | $205,000/s |
| Mastodontico Telepiedone | 5% | $275,000/s |
| Pop Pop Sahur | 1% | $295,000/s |
The rarest drop here is Pop Pop Sahur at 1%, and it also has the highest money-per-second of any unit in this block. Even the more common pulls represent a major jump in income over typical Mythic units, which is why this block is often treated as the main grind target once you can comfortably reach $15M.
Secret Lucky Block: late-game loot box
Secret Lucky Block is the premium option, both in Cash and Robux. It appears rarely on the conveyor and has the steepest Cash price.
| Property | Value |
|---|---|
| Cash cost (conveyor) | $750,000,000 |
| Robux cost (shop) | 2,399 Robux |
| Rarity | Secret |
| Appearance | Black cube with white question marks and corners, white wings |
| In-game status | Always obtainable, but spawns with a very low conveyor chance |
It can award one of five Secret-rarity Brainrots:
| Brainrot | Drop chance | Income rate |
|---|---|---|
| Torrtuginni Dragonfrutini | 74.5% | $350,000/s |
| Pot Hotspot | 19% | $2,500,000/s |
| Esok Sekolah | 5% | $30,000,000/s |
| Spaghetti Tualetti | 1% | $60,000,000/s |
| La Secret Combinasion | 0.5% | $125,000,000/s |
The economic power here is obvious: even mid-tier drops like Pot Hotspot completely outpace most other units. La Secret Combinasion is one of the rarest things you can legitimately roll, with only a 0.5% chance.
For players already at very high rebirths and income levels, this block offers the fastest way to stack huge money-per-second gains, at the cost of extreme variance.
Taco Lucky Block: Taco Tuesday special
Taco Lucky Block is tied to Taco Tuesday and Admin Abuse-style events; it does not appear in normal play outside these windows.
| Property | Value |
|---|---|
| Cash cost (conveyor) | $50,000,000 |
| Rarity | Taco (mixed Brainrot God and Secret inside) |
| Appearance | Taco-shaped block with white wings and question marks on the sides |
| In-game status | Admin Abuse / Taco Tuesday event-only |
| Brainrot | Drop chance | Income rate | Rarity |
|---|---|---|---|
| Chihuanini Taconini | 40% | $45,000/s | Brainrot God |
| Gattito Tacoto | 35% | $160,000/s | Brainrot God |
| Burrito Bandito | 10.5% | $4,000,000/s | Brainrot God |
| Los Tipi Tacos | 10.5% | $260,000/s | Secret |
| Quesadilla Crocodila | 3% | $3,000,000/s | Secret |
| Los Nooo My Hotspotsitos | 1% | $5,000,000/s | Secret |
Taco Lucky Block is notable because it mixes high-end Brainrot God and Secret units in one pool with relatively generous odds on strong earners like Burrito Bandito and Quesadilla Crocodila.
Admin Lucky Block: Admin Abuse event core
Admin Lucky Block is only spawned during Admin Abuse events and cannot be bought in normal play.
| Property | Value |
|---|---|
| Cash cost | $100,000,000 |
| Rarity | Admin |
| Appearance | Yellow block with red question-mark pupils in its eyes, white wings, and a red top hat |
| In-game status | Admin Abuse-exclusive, opens instantly |
It contains a large mix of rarities and some of the most chased Brainrots in the game:
| Brainrot | Drop chance | Income rate | Rarity |
|---|---|---|---|
| Carloo | 30% | $13,500/s | Mythic |
| Los Bombinitos | 30% | $220,000/s | Brainrot God |
| Alessio | 20% | $85,000/s | Brainrot God |
| Crabbo Limonetta | 10.25% | $235,000/s | Brainrot God |
| Blackhole Goat | 5% | $400,000/s | Secret |
| Los Spyderinis | 3% | $450,000/s | Secret |
| La Grande Combinasion | 1% | $10,000,000/s | Secret |
| Guerriro Digitale | 0.75% | $550,000/s | Secret |
| 67 | 0.25% | $7,500,000/s | Secret |
Two drops define this block’s reputation:
- La Grande Combinasion at 1% with massive income.
- 67 at only 0.25% drop chance, one of the rarest Lucky Block pulls in the game.
Because the block opens instantly, the main challenge is getting admins to spawn it and then buying or stealing it before anyone else.
Los Lucky Blocks: baby Brainrot variants
Los Lucky Blocks focus entirely on “Los” baby versions of existing units and only show up during admin events.
| Property | Value |
|---|---|

With its steep cost and strong earnings, Los Lucky Blocks are aimed at players already deep into event play who want Los-branded versions of top-tier units.

Spooky Lucky Block appeared during Halloween events and combines Admin Abuse access with a direct Candy Corn exchange.
| Property | Value |
|---|---|

| Alternate spawn method | 500 Candy Corns fed to the Jack-O-Lantern box during Halloween events |
| Rarity | Spooky |

La Casa Boo is one of the rarest Lucky Block drops overall, with only a 0.3% chance.
Los Taco Blocks: advanced Taco Tuesday variant
Los Taco Blocks are a later addition and extend the Taco Tuesday theme with “Los” versions of taco Brainrots. They are marked as Admin-Abuse-exclusive and use estimated drop odds.
| Property | Value |
|---|---|
| Cash cost | $300,000,000 |
| Rarity | Taco |
| Appearance | Three Taco Lucky Blocks joined horizontally |
| In-game status | Admin-Abuse exclusive |
The pool focuses on Los taco Brainrots; the exact drop rates beyond these estimates are not fully exposed in-game:
| Brainrot | Estimated drop chance | Base value |
|---|---|---|
| Los Chihuaninis | — | $160,000 |
| Los Gattitos | 15% | $275,000 |
| Los Cucarachas | 5.5% | $1,250,000 |
| Los Quesadillas | 2% | $4,500,000 |
| Los Burritos | 0.5% | $8,500,000 |
Because the odds are only approximations, this block is best treated as a themed collectible roll for players already comfortable with very high Cash spends.
Which Lucky Blocks are worth your money?
Every Lucky Block is a gamble, but their expected returns and risk profiles differ:
- Mythic Lucky Block suits early and mid-game players who want to push past basic Mythics without risking huge sums. The worst pulls are still usable, and the price is manageable.
- Brainrot God Lucky Block delivers some of the best consistent upgrades per Cash spent. Even common outcomes are strong earners, while Pop Pop Sahur is a long-term chase.
- Secret Lucky Block and Admin/Spooky/Los blocks are late-game luxuries. Their strongest units have enormous income rates, but the Cash and Robux costs, plus the extremely low odds on top drops, make them high-risk options.
If you are still working through early rebirths, limiting yourself to a few Mythic or Brainrot God rolls at a time keeps you from stalling your entire economy on bad luck. Once your base prints money comfortably, rotating occasional Secret, Admin, or Taco blocks into your spending can accelerate progress—but only if you’re prepared for long stretches without hitting the rarest outcomes.
Ultimately, Lucky Blocks function as intentional risk: you give up guaranteed, linear upgrades to take a swing at units that can reshape your income curve. Treat them as that kind of gamble, not as a reliable path to specific Brainrots.
