What is the highest amount obtained in a tournament?

If you're asking about freerolls then it ranges from $10 to $50 at best; that' s for 1st place. The bubble is usually $0.10 - $0.30.

My biggest tournament win was in the old PokerStars privilege freeroll, I came in third place and got $ 105. But my biggest win came from a spin & go where I made $ 125

Okay, I'm not sure if this qualifies or not. I've told this story in some other threads but it's been a couple of years since the last time.

Several years ago I won an $109 entry to a $100,000 Tournament in a freeroll. To keep the story short, after over 8 hours of play I finished 7th for a payout of $3200. I for sure won some hands that the percentages were against me. But.....
