The difference between blitz, bullet, and rapid is the amount of time you start with. The fastest rapid time control is 10 minutes. Your one blitz game was a 9 minute game.

Yesterday, I took a challenge. It looked like a normal game of "Rapid" chess, with a 10 minute time limit. When it was over, I was informed that I had just lost a game of "blitz" chess (Something I had never attempted before). So, now i have a rating of 361 in Blitz Chess, after losing one game ... and a ranking of 262 in Rapid Chess, after playing 94 games.
What is the difference between "Rapid" Chess, and "Blitz" chess?
The both looked, and felt the same to me.
