If I can't explain them right, just go on youtube and look for the guy Xplosivegaming.
Go over the world... on a box!
This was preformed in the new city, move a box with the bounce.
get on it and do the spin kick (X). you should start going in the air soon, the more you kick the higher you go, if you get stuck, DON'T WORRY. You should go down eventually. jump when you're about to hit the ground, or you could end up dye
Extreme sonic on a normal level!
First, have multi player on, (this will be cool to pull on your friends) then use the slow-mo gem and kill yourself, don't let go until the respawn (at least LOL) you go twice as fast as normal.
Grind with Silver without very hard mode on.
Most people think it's impossible for silver and shadow do do grinds or other stuff.
Just go to multiplayer with silver or shadow choose wave ocean and grind on the rails throughout the levels.
Silver's walk on water!?!?!?!?!?
When falling into water on kingdom valley hit the X button just before hitting water, you should just bump yourself right back up!
Opening two switches on multi player. (only for silver and shadow)
use shadow's or silver's shock moves, pretty easy, but kinda' hard to explain. 0_o
easy stages with sonic.
use purple gems infinite jump to get to the goal ring, also allows you to explore other characters' areas, like tails' area on wave ocean.
Tails in sonic's area!?!? ?!?!
use the purple gem to reach the island that tails is on (infinite jump before jumping onto the peices of wood that lead to the whale. switch to tails on the island. fly onto the whale (LOL, he does nothing. he has no idea wut's going on) then fly to the boards A.K.A the VERY weak bridge. :(
That's all I know for now.
coming back with more glitches soon!
