How to use Santa's Fuse machine in Steal a Brainrot

Follow these steps to operate the Santa's Fuse machine:

Step 1: Submit Brainrots

You can find the new machine placed at the center of the lobby. To operate it, you must feed it at least four Brainrot characters, which you can collect by purchasing from the Red Carpet, stealing from others, or picking from your own base. The rarity of the fused Brainrot and its fusion chances depend on the rarity of the characters you submit.

Step 2: Check the fusion chances

As you interact with the machine, a UI will appear, showing the possible fusion chances, the resulting mutations and traits, and the estimated fusion time and cash required. If you're satisfied with the numbers, you can start the fusion process.

You can also alter the results by replacing the submitted Brainrots with other ones. For instance, you can craft a Chicleteira Noelteira (50% chance), a Ho Ho Ho Sahur (48% chance), or a Cooki and Milki (2% chance) by fusing a Swag Soda, a Los Mobilis, a Uniciclino, and a Mieteteira Bicicleteira.

Step 3: Wait for the process to finish

After you pay the cash to start the fusion, you must wait for the timer to complete. Afterwards, you can claim the output and place it on your base. Note that an already fused Brainrot cannot be fused again with others.

Tip: Prioritize trying different Brainrot recipes for the best possible results from the fusion. By submitting mutated Brainrot characters, you can claim already mutated fused Brainrots.
