History VideoGame / SegaSonicBros

* SpeedRun: Well, it ''is'' a Sonic game. The game can be won in around ''three'' minutes and it records best clear times in the high score table.

* EverythingsBetterWithSpinning: The Sonics curl when spun and turn into spheres when they land.

* EarlyBirdCameo: The theme that plays from level 40 on got used on the "Get Blue Spheres" Special Stage from ''VideoGame/Sonic3AndKnuckles'', which involves converting the edges of sphere groups for extra points like in this game.

** The single-player mode ends when the player either gets over 9999990 points or clears level 99.

* {{CanceledVideoGame|s}}: As a result of its poor location-test, Sega has not acknowledged this game in any official ''Sonic'' media. This extends to Sonic's eponymous brothers, who have never been seen or acknowledged since.

''[=SegaSonic=] Bros.'' is a FallingBlocks PuzzleGame designed by Fukio Mitsuji of ''VideoGame/BubbleBobble'' fame. Although planned for a full-scale release in arcades in 1992, it didn't perform well in its location-test release and was quietly withdrawn by Sega. The game went completely forgotten outside of rumors for over two decades until information on it was disclosed in 2016 by arcade collector [=ShouTime=]. It was finally showcased to the public at the California Extreme event two years later in 2018, followed by a ROM dump on December 4th, 2018.

The game is the real origin of the recurring colored sphere items that have been known to fans since the Special Stages from ''Sonic 3''.

* CanonDiscontinuity: Due to its limited release, Sega does not acknowledge this game in any official ''Sonic'' media. This extends to Sonic's eponymous brothers, who have never been seen or acknowledged again.

* EarlyBirdCameo: The theme that plays from level 40 on got used on the Get Blue Spheres special stage from ''Sonic 3'', which involves converting the edges of sphere groups for extra points like in this game.

During gameplay, 2×2 spheres of blue, red or yellow Sonics fall into the screen and must be erased for as long as possible as you'd expect. To do that, the player must build a line of a single color such that it either surrounds a group of spheres or completes a path across any two edges of the board. The game's speed increases as time goes on, and surviving for around 20 minutes until Level 100 is one of the game's two goals. This being ''Sonic'', you can also clear the game very quickly via the alternate and difficult method of maxing out your score by clearing nearly the entire board at once several times in a row.

* NoPlotNoProblem: The game has no story and doesn't give any context for the red and yellow Sonics. Unused sprites in the data do hint at an ExcusePlot for the single player mode about rescuing Sonic's friends.

* ChuckCunninghamSyndrome: Sonic's red, yellow, and white brothers have never been seen again, though Ray and Mighty from ''VideoGame/SegaSonicTheHedgehog'' are pretty much just slightly altered versions of them.
