Secondly, the reason why campaign is run for 4 days is that if you clicked on link that's in signature, you would understand that they have four new dice races. Each race each day with the price pool of 1500 on each one. So, the campaign and the promotion ends today.
About that promotion: how the hell did the first place player sonx get so many points? 140K points the previous two days and 170K today means that in those 4 hours, they averaged 9.72 and 11.81 bets per second respectively. As far as I can tell, that's not possible to attain with consistency on the dice game: it seems to cap out around 8 bets per second.
