Sega Logo is the 22nd Expert floor in Monkey Ball and Super Monkey Ball, and the 41st Expert stage in Super Monkey Ball Deluxe. It also appears as the 151st Ultimate stage with continues, and the 191st without.
The thing that makes this floor pretty tricky and complicated is that it depends on the speed and route you are taking. This is a unique stage because it is played on a SEGA logo. This floor will take some time to master.
The traditional way to get to the goal is to go down the ramp and keep up a moderate speed while bouncing from letter to letter. This can be difficult because of the holes between each letter.
Another slightly less common way (but certainly faster) is to go down the ramp quickly, turn right and move along the bottom of the S, then hit the side of the E and get bounced all the way to A. This requires a lot of speed to pull off.
