Freebitco.in dice system is provably fair and they have high house edge of 5%. So it's very difficult to win much from their multiply game. It depends on your luck.
And we give back about 1% of that 5% house edge in the form of bonuses too!
No one is interested in those bonuses instead you reduce your house edge and make the game more fair for people to consider playing. 5% is very high and you guys simply making a lot of money from these poor gamblers. Any good reason why such a high house edge is maintaining even after many people complain?
Maybe they really wanted to make money to some poor gamblers who are expecting to win those prizes but unluckily their expectations are too high. If there are so many complains about those house edges why they didn't take any actions for this problem? Is it maybe you don't want somebody to win those games right?
