Is there a prize for all participants?
There is a 30mBTC freebet or 90 mBTC (for 1 BTC + bankroll), as long as players have made the minimum amount of bet slips during the competition.
As for the minimum ammount of bets, here are the rules that explain how you could qualify:
5. A minimum of 70 bet slips must be made during the competition to qualify for prizes.
5.1 The minimum number of bet slips required to qualify can increase if your largest winning bet is won at odds above 35.
In this case that minimum will be two times that odd.
5.1 The minimum number of bet slips required to qualify can increase if your largest winning bet is won at odds above 35.
In this case that minimum will be two times that odd.
No, that is not true. Rules changed just after competition was already over !
I haven't received 90, but only 30mBTC, even I played with bigger bankroll
I will see if there is any problem, rules did not change. If you read the OP you will see they are the same.
