The details regarding the mysterious SegaSonic Bros continue to leak out like an old dripping tap. Thanks to more information provided by and some fine detective work by the Sonic community, we now have a lot more details regarding the game and how it plays.
The biggest surprise is that this isn’t a platform game, but a puzzle game. A post made back in 2014 explains how the game worked, a rough fan translation has been doing the rounds which explains the puzzle mechanic.
The game was a falling-block puzzle game using ‘Sonic the Hedgehog’ (similar to Tetris or Puyo Puyo).
The multi-colored Sonics in round spin attack form
In a 田 shaped block, a set of 4 fall downwards. You can rotate the block, and they will pile up at the bottom, and when Sonics of the same color surround a different colord Sonic, it disappears.
This can happen by forming a ring with the same colors or by using the walls. I’ve drawn the possible scenarios below. This character ■ (Same color) represents the Sonics that surround × (which can be any color) which are Sonics that will disappear:
Using the bottom
Using bottom + one side
Using bottom + both sides
Not using the bottom (for example, making a ring) might have been allowed too, and I think you could drop one block to complete two enclosures at once, but I can’t quite recall what would happen in that case (but I imagine that they disappeared in any case like that).
If you’re a puzzle game lover, you can probably imagine the game was a bit frustrating and difficult. If you make just one mistake with placement, your plan will fall apart, and it’s extremely difficult to start stacking over again. It’s also problematic that there so many blocks, since they come down in fours.
Since the surrounded blocks can be any color, as a bit of advice, it becomes extremely important to pay attention to the color as the game progresses. It’s infuriating to throw away a block when it turns out you needed it, –unsure–
Not just limited to the falling blocks, the game further adopted the concept of ‘encircling.’ While playing, (according to the rules) while keeping track of the situation inside and outside of the boundaries, it’s necessary to follow the tracks of the boundary line. It’s a difficult game where your eyes have to take in wide scope of things all at once. That concept reappeared in some later, released games.
Fans were also able to track down an actual in-game screenshot pictured below.
ShouTime’s tumblr also updated today with another ingame screen, this time displaying the tutorial from the game.
So there you have it, this was in fact a puzzle game and not a plat-former or a prototype of the release SegaSonic Arcade game, but a completely new and original idea.
