Mutaciones
Todo sobre la Máquina de Mutaciones de Throw a Coin añadida en la Actualización 3: fusionar duplicados en variantes Grande, Enorme, Arcoíris, Astral y Divina.
Introduction
Throw a Coin has 5 mutation tiers that you can apply to items via the Mutation Machine: Big, Huge, Rainbow, Astral, and Divine. Each tier adds a cosmetic glow and (for the higher tiers) a sell-value multiplier. The Mutation Machine is the only place you can roll a Divine mutation. The Mutation Machine in Throw a Coin lets you combine duplicate items into higher-tier variants, applying a random mutation effect to the result. There are five official mutation tiers — Common, Uncommon, Rare, Epic, and Legendary — and the machine's output is heavily luck-gated, so the same item can produce very different mutated versions across runs. The exact crafting cost and craft time for each mutation tier are not published by the developer, so they are listed as unknown in the cards on this page. Use the Mutation Machine to push your best items into higher sell-value brackets and to unlock the visual glow effects that signal a successful Legendary roll.
Mutation Tier Table
Tiers
Big
Common mutation — adds a size boost. Useful filler roll. This mutation tier is the most common output of the Mutation Machine, so it is what you will see most often when feeding duplicates in bulk. The visual glow is the lowest tier, and the sell-value uplift is the smallest in the game. Refer to the feature table and FAQ on this page for the full data set, and check the cross-linked coin, rarity, or world page for additional context.
Huge
Mid-tier mutation — bigger than Big, smaller than Rainbow. This mutation tier is a mid-range output, so it requires a steady duplicate supply and at least one Mid-band pull. The visual glow is the mid-tier colour, and the sell-value uplift is moderate. Refer to the feature table and FAQ on this page for the full data set, and check the cross-linked coin, rarity, or world page for additional context.
Rainbow
Rare mutation — a full-spectrum color glow. This mutation tier is a high-end output, so it requires a high luck multiplier and a steady Late-band duplicate supply. The visual glow is the late-tier colour, and the sell-value uplift is significant. Refer to the feature table and FAQ on this page for the full data set, and check the cross-linked coin, rarity, or world page for additional context.
Astral
Epic mutation — a violet-to-cyan gradient glow. This mutation tier is the ceiling output, so it requires the full coin ladder and the highest luck multipliers. The visual glow is unique, and the sell-value uplift is the largest in the game. Refer to the feature table and FAQ on this page for the full data set, and check the cross-linked coin, rarity, or world page for additional context.
Divine
Legendary mutation — a gold-to-white iridescent glow. The chase roll. This mutation tier is the most common output of the Mutation Machine, so it is what you will see most often when feeding duplicates in bulk. The visual glow is the lowest tier, and the sell-value uplift is the smallest in the game.
Core Mechanics
You feed items into the Mutation Machine; the machine rolls one of the five mutations based on the input item's rarity and the tier of your Mutation Machine. Higher-tier inputs are more likely to land on a high-tier mutation. The exact roll probabilities and the Mutation Machine upgrade costs have not been published. The Mutation Machine consumes duplicate items and outputs a single higher-tier item with a random mutation effect. There are five official mutation tiers, each more valuable and visually distinct than the last. The mutation roll is luck-gated, so a high luck multiplier significantly increases your chance of a Legendary result. The exact crafting cost and craft time for each tier are not published by the developer.
Advantages
Big and Huge are common and add small cosmetic value. Rainbow, Astral and Divine are the chase rolls: they make the item visually unique and command the highest sell prices. Building a Cosmic-or-higher item into a Divine mutation is the most expensive single upgrade in the game. The Mutation Machine turns duplicate common drops into a single rare drop, which is the most efficient way to push your sell income up. The five-tier mutation system gives clear visual feedback, and the Legendary tier has a unique glow that signals a successful roll. The luck-gated mutation roll means high-luck players get a disproportionate share of the top-tier results.
Challenges
Mutation Machine cost, the per-mutation roll probability, and the cost to upgrade the Machine itself are not published. We refuse to list specific Robux or coin costs here. The five mutation names are fixed in-game identifiers, so they will never be rebalanced by the wiki. The exact crafting cost and craft time for each mutation tier are not published, so the Mutation Machine is hard to plan around. The mutation roll is luck-gated, so a low-luck player will see mostly Common and Uncommon results even when feeding in rare items. The machine consumes multiple items per roll, so a bad mutation is a real loss. There is no way to lock in a specific mutation effect, so the output is always partially random.

Quick Tips
Big and Huge are filler rolls — keep rolling until Rainbow or better. Do not feed your rarest items into the machine until you have a high luck multiplier. Bad rolls are a real loss, and a Legendary input deserves a Legendary luck context. This tip is part of the official Throw a Coin wiki and is updated whenever new patch data is confirmed by the developer.
Divine mutation is the chase — only attempt on Cosmic+ items. The mutation roll is luck-gated, so a high luck multiplier significantly increases your chance of a Legendary result. Plan your Mutation Machine sessions around your highest-luck coin. This tip is part of the official Throw a Coin wiki and is updated whenever new patch data is confirmed by the developer.
Mutations do not stack; rolling again replaces the current one. Common and Uncommon mutation results are the most common, so do not expect every roll to be a Legendary. Feed duplicates in bulk and accept the average result, not the best case. This tip is part of the official Throw a Coin wiki and is updated whenever new patch data is confirmed by the developer.
