I don't enter many Competitions anymore but when i was about 12 i won a Gameboy advance ( at the time they were fairly new )

Haven't really won anything else just a few scratchcard wins here and there

I also won a Nick lachey CD once which i didn't really care about...

Yes, I am very lucky in almost all situations.

I have won a Beyblade contest, 1st place, there was a ton of cool prizes.

I have also won a Jelly Belly bean count at a distant friends birthday party, I got 10 numbers away from the real number, but everybody guessed 100 less than I did.

At the movie theatre, they have a contest where you peel off a tab on the popcorn or pop. One time I pulled the tab, and I won 2 movie tickets twice.
I also went to the movie theatre's arcade, and I won 12 Months of Xbox Live Gold on a Stacking Game. I also got a 1GB iPod shuffle (An early one) from that game.

I won a Pie Eating Contest.

I am sure I won a ton of other stuff.

I've won the odd competition. I placed first in a Super Mario Bros. competition in University by getting to Level 8 - 3 in 5 minutes. I won a DVD player for my trouble which I gave to my mother.

I've also won a couple Guitar Hero competitions. I got 9 bucks and change for one in a High School, and at a bar I won a Pitcher, and a Coors Light Hat.

Unless you count the games we play at school in which there are so many team members on a team that we would win if I did nothing, I've never won a BIG, important competition. There are going to be some next year at my school, so I'll go for the win there.

I placed best in my grade for Information Technology in grade nine. That was a long time ago, though, I have no idea how I would place if there was a grade-12 level course in IT. I dunno if that counts as a competition but I got a plaque for it.

When the PS2 first came out they had set up this place in the Lakewood mall with like 30-40 PS2s. And they had a competition with like 20 people who could get the fastest time on that old snowboarding game SSX. At the end I ended not winning by like .14 of a second, I was so pissed because they guy who won got a snowboard and a ps2. And he must of sucked because I was 10 years old and he was looked like he was 30.

I remember winning a ticket to 101 Dalmations once It was for some really lame colouring-in I did. Other than that I can't really think of much.

I'm not much for competition so no I haven't won anything. Oh unless you count the Cross Screenshot competition here on Vizzed I forgot all about that XD

I'm not a competitive person, so I rarely take part in any competition, and every time I do, I don't feel stressed or something like that, because I do it just for fun .
I don't know if it counts, but I was one of the best female handball players of my school and our team was great. The biggest prize for me weren't the winnings, but the respect both of my teachers and my schoolmates
But in a couple of years I was fed up with handball and I quited.

I haven't done many gaming tournaments. I deserved to lose my first Brawl tournament at college. I made a mistake that let my opponent take my first life. When I came back I killed him almost instantly. I died the same way for my second life, then killed him. I died the same way as the first two for my third and final life. I just didn't learn.

My second college Brawl tournament was a bit more selective (only game club members could play). I got lucky because a bunch of people who could have beaten me got beaten by some other people first. I just played against a bunch of bad people until I reached the last person. My failure was even more sad than before. The person I was against used Zero Suit Samus and just kept using Down Smash to stun me and add damage, then Up+B to add a bit of damage and stop me long enough to stun. Once I got enough damage, he stunned me, then killed me. This repeated for two more lives. I still got 2nd though. I got a few prizes. He got the same as me plus an IHOP gift card and bragging rights. Big deal I don't need a gift card, so I took it as a win.
