SegaSonic Bros./ソニックブラザーズ (Arcade, 1992, Sega/Fukio Mitsuji)

This is SegaSonic Bros./ソニックブラザーズ for Arcade, and it is an unreleased arcade Sonic game that was supposed to played but only at Testing Locations in Japan. However, due to the poor reception during testing it was lost until 2018. I have never played this Sonic game before, and you may be wondering how come I never play the Sonic games. We'll all I can say is that number one I played Sonic the Hedgehog 1, 2, 3, CD and 4 back then, secondly, there too fast for me. Anyways in this game it is puzzle based, so you need to stack the Sonic's that appear from the top together to get a chain reaction to shock Robotnik. After clearing 10 levels the background will change, the music changes up, and the speed is back to normal. Also, the blue spheres music plays in this game predating Sonic the Hedgehog 3. When the board is full the game is over, but if your able to get to Level 99 you receive a Congratulation Message and then you put in your name. I may not know why this game failed testing because it is a really good game that has some unused materials that didn't make it into the original game. It is also similar to Cleopatra Fortune but that one came out four years later. On top of that this is one of the most unknown Sonic games next to Sonic Eraser, Sonic Edusoft, Sonic Crackers, and of course Sonic X-Treme.
