Rubiko and Kubiko is a Secret rarity Brainrot added in Update 58 of Steal a Brainrot. It does not appear on the conveyor belt for direct purchase like most units. Instead, you build it through the Los Traders crafting system by handing over a specific pair of Brainrots.
Quick answer: Open Los Traders and submit any one of these pairs — Rubrikiko + Los Spyderinis, Cloverat Clapat + Lovin Rose, or Bearito Cabinito + 4th Bros — to receive Rubiko and Kubiko.
Los Traders combinations that craft Rubiko and Kubiko
The primary route runs through Los Traders, a crafting feature where you exchange owned Brainrots for exclusive units. Rubiko and Kubiko accepts three separate pairs, and any single pair is enough. You do not need all three.
| First Brainrot | Second Brainrot |
|---|---|
| Rubrikiko | Los Spyderinis |
| Cloverat Clapat | Lovin Rose |
| Bearito Cabinito | 4th Bros |
Submit whichever pair you can gather first. Once the trade is confirmed, Los Traders returns Rubiko and Kubiko as the reward, and you can place it in an open base slot.
Getting it by stealing
Like every unit in the game, Rubiko and Kubiko can also be taken directly from another player’s base using the stealing mechanic. If someone has one placed and an opening appears, grabbing it skips the crafting requirements entirely. This is opportunistic rather than reliable, so the Los Traders route remains the dependable path.
Rubiko and Kubiko stats and value
Rubiko and Kubiko sits in the Secret tier and produces steady passive income once placed. It is a Duo Brainrot, pairing a living dice with a Rubik’s Cube. Both share the same winking face with their tongues out, and it stands as the first Garama reskin brought in through Los Traders.

Is it worth crafting?
At $72.5 million per second, Rubiko and Kubiko is not the top-earning Secret in the game, but it is a strong income unit for anyone who has progressed far enough to reach Los Traders. Gathering the required trade materials takes time, yet the passive earnings pay that back quickly. The dice-and-cube design also carries cosmetic appeal, which matters to players who value looks alongside output.
You will know the craft worked when Rubiko and Kubiko appears in your inventory after the Los Traders exchange confirms, ready to drop into an empty slot where it immediately begins generating income.
