From Sonic Retro
SegaSonic Bros. was developed for Sega System C2 and was originally set for release in 1992. However, the game failed its location test in Japan and subsequently did not see a nationwide release. Its existence wasn't known about for the best part of 25 years, save for a couple of overlooked posts on Twitter from 2014 and a few posts by Custom Robo developer Kohji Kenjoh on SEGA's social media website it-tells from late 2013. It only came to public attention in early 2016 when a working board was found by arcade board collector ShouTime.
Unlike traditional matching puzzle games, SegaSonic Bros. has players creating lines and loops using the different colored Sonics. Creating a line can be done by connecting Sonics of the same color across, diagonal, above, and below one another. Pieces drop from the top of the board in groups of four, with the colors randomly mixing after each drop. The object is to eliminate as many pieces on the board at once as possible. A bonus is awarded when the entire board is cleared, which multiplies the score depending on how big of a combination was executed. At every ten levels, the player is awarded a Chaos Emerald. Once the Chaos Emerald lands on the board, it will eliminate everything above and on the same plane as it. The background also changes after every tenth level, seemingly through each stage of Sonic the Hedgehog. Stages seen so far include Green Hill Zone, Marble Zone, Labyrinth Zone, and Spring Yard Zone.
Once the player reaches level 30, a fourth color is introduced, white. The game continues until the board is completely full and there is no more room to drop further pieces, or until the player reaches the maximum score of 9,999,990 points, in which case the player's clear time will be displayed on the high score table. Players compete for daily high scores and can also go head to head, racing to either obtain 300,000 points or survive longer than their competitor.
Several audio tracks were later reused in other games and/or Sega system software. (The hex and decimal IDs correspond to the two different IDs listed in the game's Sound Test, so they are not necessarily equal values.)
