Am expecting their fun to get ruined by last minute entries which is usually what happens in these crash multiplier contests.
Even though it's allowed, I feel like this is not fair. Because nobody knows who hit the max multiplier. But it's true that it's good for the contest creators and the company. If others see someone already hit the max, others will stop hunting for the multiplier because the max multiplier has already been picked. So, it's interesting to see participants playing hide-and-seek games. That locked 1 Jet sucks, I don't know why but I always get 1 locked Jet from the free wheel spins.
It is fair because it does not break any rule, not knowing other's entries is the fun and surprising part in such a contest and this makes participants to get their best by keep trying.
Of course it is all about preferences as some other may prefer to see other's entries because they can try to chase bigger multiplier but of course some people may submit lower entry in the beginning and submit the highest in the last hour or minutes.
In case LM want to make it look like active every day (not only in the last day), maybe LM can add a rule that entry should be submitted 24 hours max after the bet was placed.
Still, players may play in the last day only, so basically it will be similar in general.
