Cuboy (pronounced Q-boy) is the mascot of the indie game studio Nitrome. He made his first appearance as a face on's first favicon[1]. In certain Nitrome games, he has made several cameo appearances, but does not make an appearance as an interactive game component.


Cuboy's name is derived from the words Cube and boy, from his shape, and his gender.


Cuboy was created by Mat Annal for 1.0[2]. At that time, Cuboy had no name and was likely not meant to be an official Nitrome character. Mat Annal created Cuboy by drawing a pink square and giving it the face of Hot Air.[2] .

Later, when the NES skin was being created, as a joke, Jay D. Smith[2] drew Cuboy with arms and legs and put him into the skin. When Nitrome was overhauling the site to 2.0, Stefan Ählin often drew Cuboy for use on the site.[2]

Physical appearance

Cuboy has two appearances, his modern appearance used mostly for Nitrome blog posts, and his classic appearance, his most widely used appearance.

Classic appearance

Cuboy16x16Cuboy's classic appearance, which is Cuboy's regular appearance, is Cuboy's most widely used appearance. This appearance depicts him as a pink coloured square with two white rectangular eyes, purple cheeks, and a mouth appearing as a D shape rotated on its side. Although he originally appears pink, in some games, he does not always use have this color when featuring him as a cameo.

Notable appearances

The classic square appears in the 100th Game skin together with another cuboy in the background but saddened with crossbones.

Cuboy's classic appearance and his name appears on the Profile button of 2.0.

In the NES skin, many differently-coloured classic appearance Cuboy faces appear.

Modern appearance

Cuboy14x14Cuboy's face also gains a modern appearance, shape has rounded corners, and the same with his limbs. His overall face is also smaller.

Cuboy's modern appearance was first used on the Nitrome blog, and has been used for various art throughout Cuboy appears as he does when in his square appearance, only bigger, his face having more detail, and that he has two small little legs and two small little arms.

Alternate appearances

Cuboy has not appeared as his regular self all the time; he has appeared differently multiple times for different occasions.

Friday updates

Cuboy's appearance is sometimes altered to commemorate certain occasions.

  • Queen Elizabeth's Diamond Jubilee(date unknown) - Cuboy is shown in the Friday update wearing a hat and holding two flags.
  • Winter 2011 - To celebrate the winter holidays, Nitrome dressed Cuboy in a Santa hat, with snow falling in the background.[3]
  • Touchy's release - Cuboy is shown with wings and an angelic expression on his face on the first Friday update after Nitrome Touchy was released.[4]
  • 90% completion - Cuboy wears a Viking helmet in the Friday update of November 16, 2012. This update announced Icebreaker iOS' progress of passing the 90% mark to completing development of the game.[5]
  • Android release - Cuboy wears an Android costume and is placed between two Nitrome Touchy devices.[6]
  • Flightless - Cuboy wears is seen in the December 7th 2012 Friday update wearing the hats of the ducks from Flightless.
  • Winter 2012 - Similar to the winter of 2011, Cuboy is shown wearing a Santa hat. At the same time, he is being kicked by a vanilla ice cream character. This update, posted on December 21, 2012, was to correspond with the release of Bad Ice-Cream 2, also on the same day. His speech bubble reads, "Merry Christmas!"
  • Winter 2013 - In this update, posted on December 20, 2013, Cuboy appears as a snowman. This blog post was announcing Nitrome leaving the office for Winter break, so Cuboy's speech bubble reads "We're off!".
  • Icebreaker A Viking Voyage Android release - Cuboy appears as a viking next to a pink hammer with a Cuboy face on it.
  • Nitrome Jam - Cuboy appears as a can of jam that has "2014" on it, which was used for the May 30, 2014 Friday update right before the Jam.
  • Turn-Undead - Cuboy appears wearing a hat that the main character wears.
  • Halloween avatars - In a blog post posted on October 24, 2014 announcing Halloween avatars, Cuboy is seen wearing a Halloween pumpkin.

Thursday updates

Occasionally, Nitrome provides Thursday updates on their blog when they will not be at their office on that Friday. This is usually because of a holiday. In these Thursday updates, Nitrome sometimes uses an image of Cuboy saying "Thursday!?", indicating that it is not usual for there to be a weekly update on Thursday instead of Friday.

Other appearances

Another change for Cuboy came for the demo advertisement, which depicted a transparent Cuboy with only an outline of his body and face being present, giving the sense of a blueprint.

What seems to be an 8-bit Cuboy can be seen on the "Touchy" button on the Navigation panel, as well as a picture of his head on the Profile button.

NES appearances

Cuboy's NES appearance is Cuboy's least appearing appearance, given this name as it has only been seen on Nitrome Enjoyment System (NES) material. This appearance depicts Cuboy as having a rectangular body, being taller than in his modern appearance. Cuboy has two small, stubby hands and two small, stubby feet.

This appearance is not much different than Cuboy's modern appearance, other than this appearance (NES appearance) giving Cuboy a tad longer face, Cuboy's face lacking detail, and appearing more cube like.

This face also appears on the Nitrome seal of approval, Nitrome's parody of the Nintendo Seal of Approval.


After it was accepted as a Nitrome character on November 15, 2010[7], Cuboy began to appear much more often in Nitrome related content.

Cuboy's possible first appearance was when 1.0 was launched, represented on the favicon for the site in his classic square appearance. His remained unnamed until November 15, 2010, when the first Nitrome blog post about the Nitrome Enjoyment System box revealed the mascot's name to be "Cuboy" on the Nitrome Seal of Approval.[8].

Prior to the revealing of his name, Cuboy could only be seen in a few site areas of, but had not made any in-game appearances. It was after the revealing of Cuboy's name that he first appeared on the NES skin, previewing Nitrome Tetris.

With the release of 2.0, Nitrome began posting Friday updates. Every Friday, highlights from earlier posts that week would be recapped. These posts would feature an image of Cuboy shouting, "Friday!" On special occasions, or when a Friday update is missed, the image would be altered to match the occasion. When Nitrome missed a Friday update, they instead opened with a similar Friday post, only with Cuboy saying, "Tuesday?" instead of "Friday!" Nitrome's December 22 update in 2011 featured an image of Cuboy wearing a Santa hat[8].


Cuboy has made several appearances across multiple Nitrome media. Below is a list of all its appearances, sorted into sub-sections by game.


Cuboy game

Main article: Cuboy game

Cuboy appears as the hero of this Rainbow Island parody. Cuboy apparently can jump, walk on platforms, and throw hammers (all this evident from the screenshot of the game). Cuboy appears in his NES appearance.


In an image taken from the NES skin, Cuboy appears as the host of a multiplayer Nitrometris. Tetris blocks used in the game (and Mega Mash) appear to have Cuboy's classic square appearance, these faces coming in pink, green, yellow, red, purple, and cyan. Cuboy in the NES skin image appears in his NES appearance, while the Tetris blocks appear in Cuboy's classic square appearance.

Hot Air series

See also: Hot Air (Character)#Design

Cuboy's design of his face in its classic square appearance probably influenced the appearance of Hot Air's face, as both have the two rectangular eyes, purple cheeks, and happy mouth. This basic appearance was also carried over into Hot Air 2, where all balloons present in the game (minus the ones made in Hot Air Balloon Maker) were likely designed around Cuboy's face.

Although Cuboy did not appear in Hot Air 2, the house of his wife is obviously based off Cuboy's face, as it features the basic appearance of Cuboy's classic square face (rectangular white eyes, 2D circle cheeks, and happy mouth). This house seems to be the most Cuboy like, as along with having Cuboy's basic facial features, it is coloured pink.

Square Meal

The stone blocks in level one of Square Meal are arranged to look like Cuboy's classic square face.

Snot Put series

Cuboy's classic square face seems to have influenced the face of the snot.

In one of Nitrome's Facebook posts, they had an advertisement encouraging fans to vote for Flightless on Steam. In the advertisement, Cuboy is seen in the thought bubble of one of the main characters, the green duck. The Cuboy square also has a heart above it, perhaps implying that the duck loves Nitrome, since Cuboy represents Nitrome.

Nitrome Must Die website

Anonymous Cuboy favicon

The favicon of the site is white Cuboy head that is constantly spinning. This head is possibly meant to be Cuboy's skull, fitting with the theme of the website of killing Nitrome. Interestingly, this is the only situation where the back of Cuboy's head is actually seen. The favicon also seems to look like Cuboy is wearing an Guy Fawkes mask.

Along with this, grey Cuboy faces are seen in the background, only having crossbones under the face, and on the face having an upside-down smile.

Nitrome Towers

Cuboy's face has been a major influence of Nitrome's early work. Many enemies of the Hot Air series have their face based off Cuboy's. Cuboy has not only influenced Nitrome's first series, but even the art of the snot from Snot Put. Even around the time of the NES skin, Nitrome used various forms of Cuboy.




  1. Cuboy makes appearances as Nitrome's mascot, on the box of the Nitrome Enjoyment System (Cuboy Seal of Approval) ,has appeared in several places across, and made many cameos in games.
  2. 2.0 2.1 2.2 2.3 2.4 Nitrome Blog: - Blog FixesComment by Nitrome:
    He is not in any Nitrome game! Originally the site was pink and when I made an emoticon thing that shows next to the site in the URL address/search bar I made it a pink square with the hot air face. I think it was one of our artists Jay that first drew Cuboy as a character with arms and legs as a joke in the NES skin then Stefan drew him a lot when we overhauled the site at one point. He has became our mascot of sorts along the way. I'm not sure if we will ever put him in a game as the staring character. It would seem odd somehow to have our mascot be from one of our games when we have so many characters in the ones that we already have. Mat
