In fact, there are actually only 128,016,000 distinct level layouts (or stages). (Note, as mentioned above, collecting every ring and scoring a perfect allows players to advance ten levels.) Once a player reaches the final level, the sequence repeats from the beginning.
#GET ALL BLUE SPHERES CODE#
If a level is completed with all of the rings collected, the player receives a " perfect" grade and advances ten levels instead of just one.Īfter completing a level, the player is given a 12-digit code (password) for the level, and shown the stage difficulty.īlue Sphere has 134,217,728 (2 27) levels, which are played in sequence. There is a slight difference between these stages and those in Sonic the Hedgehog 3 and Sonic & Knuckles in Blue Sphere, the ring counter counts down instead of up. These rings can be revealed by surrounding blocks of blue spheres completely by an outline of red spheres-the entire block will then be turned into rings. Some rings will be already visible in the stage, others will be hidden. In addition, the stages will contain a set number of rings to collect.
#GET ALL BLUE SPHERES FULL#
Collecting all blue spheres will award the player with a Chaos Emerald and (if the full game has been accessed) progress to the next level. Silver bumpers with red stars bounce the player, causing them to run backwards for a short time (until the player pushes forward on the D-pad), and orange spheres catapult the player a certain number of squares forward. The player must run around the surface of a 32x32 wrapping square (torus), collecting blue spheres while avoiding red spheres. (The player cannot play as Tails, or as Sonic and Tails together.)īlue Sphere levels are based on the Special Stages from Sonic the Hedgehog 3 and Sonic & Knuckles. Pressing, , or will switch the playable character between Sonic (represented by blue-star bumpers either side of the word 'START') and Knuckles (represented by red-star bumper). The main menu of Blue Sphere will show the current level number along with a 12-digit code (password) that will allow the player to jump back to the current level.

It can also be accessed from the file menu's special stage selection in Sonic & Knuckles Collection for PC. In Sonic Mega Collection and Sonic Mega Collection Plus, Blue Sphere can be unlocked separately (in the former case by playing Sonic the Hedgehog and Sonic 3D Blast 20 times each) and is accessible by itself from the game listing. In Sonic Jam, it can be accessed by "locking-on" Sonic 1 to Sonic & Knuckles. Locking on Sonic & Knuckles to another copy of Sonic & Knuckles will also load the game normally.īlue Sphere is also available in certain compilation games. Some cartridges with particularly large ROM file sizes (including Phantasy Star IV: The End of the Millennium and Super Street Fighter II: The New Challengers) will not load Blue Sphere, but will instead boot Sonic & Knuckles as normal. Most other cartridges will allow the player to access only a single stage of the game, based on the cartridge's ROM header and the stage's code in the full Blue Sphere game. If the cartridge that is locked on to Sonic & Knuckles is the original Sonic the Hedgehog ( Sonic Classics, the Nick Arcade and Simon Wai prototype versions of Sonic the Hedgehog 2 will also work), then the full game of Blue Sphere is accessed with all stages. The scrolling text will be replaced by "Get Blue Spheres!" When a Mega Drive game cartridge other than Sonic the Hedgehog 2 or Sonic the Hedgehog 3 is locked on to the Sonic & Knuckles special cartridge, a screen appears with the Sonic & Knuckles logo, models of the characters Sonic, Tails, Knuckles and Robotnik, and a line of scrolling text that says "No Way! No Way! No Way! No Way?" While this screen is visible, pressing, and at the same time changes the screen to the Blue Sphere menu.
