All Kick a Lucky Block Mutations Guide & How to Get Them (June 2026)

If you have been grinding away in Kick a Lucky Block on Roblox and wondering why some players earn way more than you, the answer is almost always mutations. Mutations are the single biggest income booster in the game, turning an average brainrot into a serious earner with multipliers that go as high as 11x. In this guide, I break down every single mutation available, what each one does, how rare it is, and the exact methods you need to start getting them yourself. Whether you are a brand-new player or someone chasing that elusive Cyber mutation, this guide has everything you need.

What Are Mutations in Kick a Lucky Block?

Mutations in Kick a Lucky Block are special modifiers that change both the appearance and income output of your brainrots. When a mutation is applied, the brainrot gets a visual makeover and its income gets multiplied by a specific value tied to that mutation type. Unlike traits, which stack on top of each other, each brainrot can only hold one mutation at a time.

Here is how the income calculation works. Your brainrot has a base income value. The mutation multiplier gets applied directly to that base. So if a brainrot earns 100 coins per cycle and it lands the Diamond mutation (which carries a 5x multiplier), your new income becomes 500 coins per cycle. That is a massive jump from a single modifier.

The rarity of each mutation determines how likely you are to find one when kicking lucky blocks. Common mutations like Gold show up relatively often, while something like Cyber or Divine is extraordinarily rare. I cover the exact spawn chances for each mutation in the sections below.

All Kick a Lucky Block Mutations List (2026)

This section covers every confirmed mutation in the game as of 2026. I have organized them into two categories: permanent mutations that are always available, and limited mutations that only appear during special events or seasonal updates.

Permanent Mutations

Permanent mutations can be obtained at any time by kicking lucky blocks. They are part of the core game and will not be removed. Here is the full list:

• Gold Mutation – Multiplier: 2x. The most common mutation in the game. Gold gives your brainrot a shiny golden appearance. While 2x is not the biggest boost, Gold mutations appear frequently enough that most players will collect several within their first few hours of play. Spawn chance is roughly around 15-20%.
• Diamond Mutation – Multiplier: 5x. A significant step up from Gold. Diamond turns your brainrot into a sparkling blue crystalline version. At 5x your base income, this mutation can genuinely change your earning trajectory. Diamond has a spawn chance of approximately 5-8%, making it uncommon but not exceptionally rare.
• Plasma Mutation – Multiplier: 7x. Plasma gives off an electric purple glow and sits firmly in the upper tier of permanent mutations. With a 7x multiplier, a single Plasma brainrot can out-earn five regular ones. The spawn chance drops to around 2-4%, so expect to spend some time hunting for this one.
• Molten Mutation – Multiplier: 8x. Molten covers your brainrot in a dripping lava texture with an orange-red glow. It is one of the most visually striking permanent mutations. At 8x income, it is only slightly behind the event-exclusive rarities. Spawn chance sits around 1-3%.
• Radioactive Mutation – Multiplier: 9x. Radioactive gives your brainrot a neon green, glowing aura that pulses. This is the rarest of the permanent mutations with a spawn chance estimated at 0.5-1.5%. Landing a Radioactive mutation is a real milestone moment for any player.
• Bloodrot Mutation – Multiplier: 6x. A deep crimson red mutation with dark tendrils. Bloodrot sits between Diamond and Plasma in terms of power. It is considered uncommon with a spawn chance around 3-5%.
• Cursed Mutation – Multiplier: 10x. The Cursed mutation wraps your brainrot in dark smoke with eerie visual effects. At 10x, it rivals the rarest event mutations in raw power. Spawn chance is extremely low, estimated at under 0.5%. The developer has been expanding Cursed-related content, so this mutation may become more relevant in future updates.

Limited and Event Mutations

Limited mutations are only available during specific events, seasonal updates, or special game occurrences. Once the event ends, you can no longer obtain these mutations through normal gameplay. Here are the known limited mutations:

• Cyber Mutation – Multiplier: 11x. Currently the highest multiplier in the entire game. Cyber gives a futuristic neon blue and circuit-board aesthetic. It was introduced as part of a limited-time event and is the most sought-after mutation in the community. Spawn chance during its event was under 0.3%. Many players missed this one entirely.
• Galaxy Mutation – Multiplier: 9x. Galaxy covers the brainrot in a swirling cosmic pattern with stars and nebula effects. It was available during a space-themed event and shares the same multiplier as Radioactive. Visually, it is one of the most impressive mutations in the game.
• Rainbow Mutation – Multiplier: 7x. Rainbow cycles through every color in a smooth animated gradient. It was released during a celebration event. While its multiplier matches Plasma, the visual appeal makes it a collector favorite.
• Lava Mutation – Multiplier: 8x. Similar to Molten but with a distinct volcanic rock texture and bright orange cracks. This was part of a seasonal content drop. At 8x it matches Molten in power but has a completely different look.
• Yin Yang Mutation – Multiplier: 6x. A black and white split design that alternates between light and dark halves. Released during a balance-themed event. Solid mid-tier option with a clean aesthetic.
• Candy Mutation – Multiplier: 5x. A pastel-colored, candy-coated appearance. This was part of a holiday-themed event. It matches Diamond in multiplier but is much rarer due to its limited availability.
• Divine Mutation – Multiplier: 10x. A radiant, golden-white glow with heavenly particle effects. Divine is one of the rarest event mutations ever released. At 10x, it ties with Cursed and is only beaten by Cyber. This mutation is a true trophy piece for collectors.

Kick a Lucky Block Mutation Rarity Tier List 2026

One thing the community constantly asks for is a clear rarity ranking, so I put together this tier list based on spawn chance data from the wiki and community reports. Tiers go from Common up to Mythical.

• Common Tier (15-20% spawn) – Gold (2x). This is the mutation you will see most often. Good for beginners who need any boost they can get.
• Uncommon Tier (3-8% spawn) – Bloodrot (6x), Diamond (5x), Candy (5x, limited). These show up often enough that dedicated players will find them within a few sessions.
• Rare Tier (1-4% spawn) – Plasma (7x), Molten (8x), Rainbow (7x, limited), Lava (8x, limited), Yin Yang (6x, limited). You need some luck and persistence to land these. The limited ones are especially hard since the event window is narrow.
• Epic Tier (0.5-1.5% spawn) – Radioactive (9x), Galaxy (9x, limited). These are the mutations that make players stop and screenshot when they finally get one.
• Legendary Tier (0.3-0.5% spawn) – Cursed (10x), Divine (10x, limited). Finding one of these is a genuine highlight. Players often share these moments in community forums.
• Mythical Tier (under 0.3% spawn) – Cyber (11x, limited). The rarest mutation in the game by a significant margin. Only a small fraction of the player base has ever obtained Cyber, and its event has already ended.

Keep in mind that these spawn chances can shift during global luck events or when the developer adjusts rates. The percentages above reflect typical, non-boosted conditions.

How to Get Mutations in Kick a Lucky Block?

Getting mutations is not complicated, but maximizing your chances requires understanding the mechanics. Here are the three main methods:

Master the Perfect Kick Technique

The perfect kick is the core skill in Kick a Lucky Block, and it directly affects your mutation chances. When you kick a lucky block, timing matters. A perfect kick happens when you hit the block at the exact right moment during the kick animation. The game gives you a visual cue, usually a flash or a specific color change, that signals the perfect timing window.

Here is how I practice it: watch the block closely as your character winds up the kick. There is a brief moment right before impact where the block will shimmer or pulse. That is your window. Hitting it consistently takes practice, but even improving from 50% to 70% perfect kicks will noticeably increase your mutation haul over time.

A perfect kick does not guarantee a mutation, but it significantly raises the probability compared to a regular kick. Think of it as rolling dice where perfect kicks give you more rolls.

Take Advantage of Global Luck Events

Global luck events are server-wide boosts that temporarily increase mutation spawn rates for everyone playing. These events happen periodically and are announced in the game. During a global luck event, every mutation becomes easier to find. A mutation that normally has a 1% spawn chance might jump to 3-5% during these events.

The best approach is to save your play sessions for when global luck events are active. If you see the event notification pop up, prioritize kicking as many blocks as possible during that window. Some events last only 15-30 minutes, so every second counts.

Players on Reddit have confirmed that their rarest pulls almost always happened during global luck events. I have seen multiple community posts where players landed Radioactive or Cursed mutations specifically during these boosted windows.

Mutation Luck Gamepass

The Mutation Luck gamepass is a Robux purchase that permanently increases your base mutation chance. It costs 139 Robux and applies a flat boost to your spawn probability for all mutations. This boost stacks with global luck events and perfect kicks, making it the most efficient investment for players who are serious about collecting mutations.

Is it worth it? If you play regularly and plan to keep grinding for mutations, absolutely. The gamepass pays for itself quickly in the extra income you generate from finding more mutated brainrots. If you only play casually, you might want to skip it and rely on global luck events instead.

Best Strategies for Getting Rare Mutations

Beyond the core mechanics, there are several strategies that experienced players use to improve their odds:

• Play during off-peak hours. Fewer players on the server can sometimes mean less competition for block spawns, giving you more kicks per minute. This is not a confirmed mechanic, but many top players swear by it.
• Stack all three luck boosters. Combine perfect kicks, global luck events, and the Mutation Luck gamepass for the highest possible spawn rates. When all three align, even Epic and Legendary tier mutations become realistic targets.
• Focus on volume. Mutations are a numbers game. The more blocks you kick, the more chances you get. Set a goal of at least 100 kicks per session and stick with it. Over time, the law of averages works in your favor.
• Trade wisely. If the game allows trading, consider trading multiple lower-tier mutations for a single higher-tier one. A player with three Diamond mutations might be willing to swap for one Plasma, which benefits both sides.
• Watch for developer announcements. The developer occasionally announces rate boosts, new mutations, or returning limited events. Following the game’s official channels gives you advance notice so you can plan your play sessions around these windows.
• Do not reroll good mutations. If you land a Rare or Epic mutation, keep it. The temptation to keep rolling for something better is real, but the math rarely works in your favor. A guaranteed 7x or 8x brainrot is worth more than a tiny chance at a 9x or 10x.

Mutations vs. Traits: What Is the Difference?

This is one of the most common questions in the community, and for good reason. Both mutations and traits modify your brainrot, but they work differently.

Mutations are single-slot modifiers. Each brainrot can have exactly one mutation at a time. Mutations change the visual appearance dramatically and apply a large income multiplier. You get mutations by kicking lucky blocks with a random spawn chance.

Traits are separate modifiers that can stack on top of mutations. A brainrot can have one mutation plus multiple traits. Traits tend to offer smaller, incremental bonuses rather than big multipliers. Think of mutations as your big income engine and traits as fine-tuning dials.

The key takeaway: always aim for a mutation first, then stack traits on top. A 5x Diamond mutation with good traits will outperform an unmutated brainrot with perfect traits every time.
