I find it very hard playing on mobile, are you going to optimize your games for mobile devices?
At the moment no, but will see what can be done in the future. Dice should scale fine.
Adjustable House Edge (dice)
As I see, the house edge can be set from 0.8% to 5% by the player, but what is the point of having that? Why would a player choose a higher house edge?
The house edge affects the max profit on a single bet, if you change the house edge and look at the max profit field you will see how it changes.
