i found something strange with my bets roll dice numbers are really amazing for me, take a look at this and see what is happening there first bet# 34434765 and than i got # 34440197, it is hard to understand why it got reduce instead of increase bet number.

It did increase?
First bet 34434765 next bet 34440197 a difference of +5432
yes it increase if you are online at safedice than you can see there all bets status are not get being updated real time so that is why i was wonder to see my bet number like this, is admin is performing some kind of maintenance there to resolve this issue?
if im not mistaken, i think the increase is from the btc bets..
oh, now I get it.

yes waterpile is right. check the timestamps of your bets. between those two 0 bets ~5k bets with btc happenend.
while there are separate stats for both branches(btc & xmr), the betids are global.
