That's a great promo, and it's a pity that I missed it. But what I really miss is the "Slot Master Guessing Game" run by Duelbits on this forum some time ago. I hope they will renew this challenge.
I even forgot that duelbits had held an event like this here, just remember how often they held multiplier slot events, now duelbits is promoting more heavily through their website so players who only occasionally have to check email often because duelbits sends offers via email and this is an offer which lasts a short period of time because I received the email but read it too late
Yes, it had been run for several months, and surprisingly few people were participating, like from 10 to 20 people, on average, while the prizes were good, actually. During the contest I was addicted to it, kind of, and sometimes was spending over 3 hours trying to guess the slot. But when that extremely difficult task was solved, it felt so good.
I should say, it wasn't your typical "guess the slot" game, like on twitter or facebook. It was really hard, and that was the beauty of it.
