One is a light blue Arabic numeral one (1), being based off the design of the "1" with a base (𝟷), likely taken from the original Minesweeper. The diagonal part and base of the "𝟷" are misaligned, the former more far off to the left. Unlike almost all well-known Algebraliens, One doesn't have any arms. Prior to her isolation, One appears to be a nice but lonely person, eager to make friends with the others. However, she also acts impulsively and doesn't realize what she's doing until it's too late. She tries hard to patch things up that she did wrong, in fear of not being accepted and remaining alone. Even in the present day, she is still hurt by her loneliness.

Two appears to be a green Arabic numeral two (2), with their green color being based off from the original Minesweeper. Two is drawn in the same style as Four and X, as they have limbs that are a lighter shade of green, being drawn simplistically and having four fingers. However, one thing to note is Two's face is located on the upper section of their body unlike Four and X, whose faces are located on the middle of their bodies. Two is shown to be a more easygoing, silly, and casual British host. Compared to Four, they are nowhere near as sadistic and act very reasonably with the contestants most of the time. Although, Two's more passive approach leaves them susceptible to getting pushed around by the contestants when they mess things up.

Four, as his name suggests, appears to be a blue Arabic numeral four (4), whose design is based on the version of "4" with an open top, most likely taken from the original Minesweeper. He is drawn simplistically and have limbs that are lighter colored. Like every algebralien, Four has four fingers. Whenever disgusted, he can have a more teal colored body. Four is chaotic in behavior but will stay calm towards the ones he cares about most.

X is a drawing of the letter X with a yellow body and lighter yellow limbs. Similar to Four, they are purposefully drawn simplistically, with different assets and four fingers. He's a lot more friendly than Four but that doesn't mean he won't be soft enough for anyone to push him around as he can be just as erratic and chaotic as Four sometimes.
