The game was published for Acorn Electron, Amstrad CPC, BBC Micro Model B, Commodore 64, VIC-20, Dragon 32, MSX, Oric Atmos, and ZX Spectrum at £8.95 for each part.

Several sources state, erroneously, that Hareraiser is based on Masquerade - in fact, the only thing apart from the prize that the two have in common is that both feature a hare.

Haresoft was founded by Dugald Thompson, the controversial winner of Masquerade, and his business partner John Guard.

[4] Haresoft claimed the game was released in two parts "to make it fun and enable competitors of all ages to participate".

Ashen further stated that he believed the puzzle was intentionally designed to be unsolvable so that Haresoft would not lose the art piece (the golden hare).
