Snow Bros.[a] is a 1990 platform arcade video game originally developed by Toaplan first published in Japan, then in North America by Romstar and later in Europe.

Starring the eponymous snowmen twins Nick and Tom, players are tasked with travelling through 50 stages, throwing and building snowballs, jumping on and off platforms to navigate level obstacles while dodging and defeating monsters in order to rescue the princesses Puripuri and Puchipuchi from captivity.

[1] Although first launched in arcades, the game was later ported across multiple platforms, each one being created by different third-party developers and featuring several changes or additions compared with the original version.

Snow Bros. was met with mostly positive reception from critics and players alike, earning an award from Gamest magazine and gaining a cult following since its initial release.

Getting hit by enemy fire will result in losing a life, as well as a penalty of decreasing the characters' firepower and speed to his original state and once all lives are lost, the game is over unless the players insert more credits into the arcade machine to continue playing.

[6][7][8][9] Ocean Software acquired the license after the European Computer Entertainment Show in September 1990 while work on the port immediately began as soon as programmer Pierre Adane finished his task of converting Pang.

[10] Despite receiving almost no support from Toaplan, the team at Ocean France wanted the Amiga port of Snow Bros. to be as close as possible to the arcade original, playing the coin-op machine from start to finish while using it as reference when taking notes about certain elements such as animations, graphic techniques and enemy AI.

[10] Work on the conversion was primarily done on Amiga and Atari ST-based systems, while custom software was written to animate sprites and build stages as a jigsaw puzzle using low memory, which allowed an easier coding process to implement every element from the arcade version like hidden bonus secrets.

[10] Artists Philippe and Lionel Dessoly, as well as Francis Fournier adapted the arcade artwork for the conversion, using a ST set-up for maps and sprites, while Pierre Loriaux was responsible for sound design.

[10][11] The crew also included new additions such as cutscenes between stages and Adane was also able to replicate the original gameplay speed, though alterations had to be made to make the game more playable.

[21] The same year on 21 October, an album containing music from the title and Out Zone was co-published exclusively in Japan by Scitron and Pony Canyon, featuring an arranged soundtrack composed by Ōta.

[21] The Game Boy conversion, titled Snow Bros. Jr., was developed by Dual and first released in Japan by Naxat Soft on 24 May 1991 and later in North America by Capcom in January 1992.

The Nintendo Entertainment System version, titled Snow Brothers in western regions, was developed by Soft House and first released in North America by Capcom in November 1991, then in Japan on December of the same year by Toaplan as well as in Europe.

[74] In 2002, a Mexican company known as Syrmex Electronics created a hack of the original Snow Bros. running on similar hardware called Snow Brothers 3: Magical Adventure, replacing Nick and Tom with soccer players who shoot soccer balls instead of snowballs, while featuring levels similar to those of the original despite new graphics and artwork added to the levels' backgrounds.
