Mutations in Jump to Steal Soccer Players raise a soccer player's sale value and money per second. As of the Spain Update, the game lists nine mutations: Golden, Diamond, Rainbow, Cursed, Volcanic, Toxic, Taco, Cosmic, and Slimey.
Known multipliers sit between 2x and 3x. Rainbow, Taco, and Cosmic top that known set. Cursed and Slimey are on the list, but their numbers are still blank.
You get mutated players by opening Lucky Blocks. Matching mutated Lucky Blocks and weather events push the odds higher.

How to get mutated players
Carry Lucky Blocks to your base and open them.
Any map-spawned Lucky Block has a small chance to roll any mutation. Other players can still contest the path home, so treat a good block like a short heist, not a casual stroll.Prioritize mutated Lucky Blocks when you see them.
Special blocks such as Volcanic, Cosmic, and Poison Lucky Blocks give a higher chance of their matching mutation. Naming is a little crooked: Poison blocks feed Toxic, not a mutation called Poison.Check the event board above the Upgrade Shops.
Weather events spawn on a random timer. The board shows which event is next, so you know when to stop wandering and start farming.Farm during the matching weather event.
Mutated Lucky Blocks can appear in all map areas. Their spawn chance rises while the matching event is live. Watch the odd labels too: Galaxy Event feeds Cosmic, and Gold Event feeds Golden.
Every mutation and what it multiplies

Each known multiplier applies to both sale value and earning rate on that player. Cursed and Slimey stay open until their stats are found.
| Mutation | Multiplier | How to get |
|---|---|---|
| Golden | 2x | Golden Lucky Blocks during the Gold Event |
| Volcanic | 2x | Volcanic Lucky Blocks during the Volcano Event |
| Toxic | 2x | Poison Lucky Blocks (natural spawns and the Toxic Event) |
| Diamond | 2.5x | Diamond Lucky Blocks (natural spawns and the Diamond Event) |
| Rainbow | 3x | Rainbow Lucky Blocks during the Rainbow Event |
| Taco | 3x | Taco Lucky Blocks during the Taco Event |
| Cosmic | 3x | Cosmic Lucky Blocks (natural spawns and the Galaxy Event) |
| Cursed | Unknown | Unknown |
| Slimey | Unknown | Unknown |
Among known values, chase Rainbow, Taco, and Cosmic at 3x when those events are up. Diamond at 2.5x is the strong middle tier. Golden, Volcanic, and Toxic at 2x still beat a plain player: same job, better paycheck.
Skip building your income plan around Cursed or Slimey for now. They sit in the Spain Update set, but their multipliers and best obtainment paths are not known yet.
