I guess will not accept on the event multiplier and on the system CHIPS.GG, buying feature calculation 100x = 1x multiplier so because of that can be the entry counts as 8x multiplier. But at least he won a good money on that bonus future.
There is no rules like "buy feature is not allowed", so I guess it is allowed but I'm not really sure how about the multiplier is counted with the buy feature.
Is it based on the base bet or based on the cost of the buy feature.
If it is based on the base bet then his multiplier is indeed 890x but if it is based on the cost of the buy feature then his multiplier is only 8.9x
It would be nice if Hhampuz clarify about this thing as he manage some different multiplier contests with different rule about "buy feature".
Of course it is not going to be simple, of course it is going to take some time, but the reality is that we do not need to chase every promotion there is, why not just regular gambling which is once again I am telling that it is hard because you end up losing most of the time but if you have fun that way the most, there is no need to chase for it neither. That is all my opinion of course.
