Right Krateis cube reward system:

If there were more than 4 people participating in event, rewards should be counted in a different way.

Lets say there were 5 people participating in Kratei cube. Interpid, Q.I, lord_rex, lewzer, Stake.

Interprid achieved 130 points
Q.I achieved 100 points
lord_rex achieved 38759436786234 points
lewzer achived 110 points
Stake achieved 140 points

So, now the system should give rewards like this:

Highest score player in this case is lord_rex, he achieved 38759436786234 points so he is TOP1 and he get 40 Fantasy isle coins
Second score player in this case is Stake, he achieved 140 poitns so he is TOP2 and he get 20 Fantasy isle coins
Third score player in this case is Interprid, he achieved 130 points, so he is TOP3 and he get 10 Fantasy isle coins
Fourth score player in this case is lewzer, he achieved 110 points so he is TOP4 and he get 10 fantasy isle coins
Fifth score player in this case is Q.I, he achived 100 points so he is TOP5 and he get 10 fantasy isle coins

Basically, everyone who is TOP3, TOP4, TOP5, TOP6 and so on will get 10 fantasy isle coins, while TOP1 gets 40, TOP2 gets 20.
