Anyone who traded on this market can roll 0-420 on the Fairly Random bot by writing "@FairlyRandom min=0 max=420" in a comment (Each person are allowed one roll per day)

Whoever rolled 69 is the winner, and gets a 2000 Mana prize. Market resolves Yes.

If No one managed to roll 69 before market closes, Market resolves No.

If you rolled before trading on this market, your roll is voided. You are welcome to roll after placing a bet.
If you already rolled today, you are welcome to roll again the next day (I'm not super strict on what counts as the next day, just make sure you wait at least 20 hours before you do your next roll)
