2.When you guys will add the ''Roll Over '' option?
When was your last time play on this site? The roll over option has been added yesterday IIRC, so you can use it already.
Btw why do we need roll over? You can only play on low number though no need to place bet on high, it will still be the same like normal dice. You will keep on play lower range
Of course it is needed, players need a variance on what they are going to bet. Some people like to switch between under/over when they play. If there is no option to choose between over/under, so it is not a complete dice game imho.
