Games look very basic and designs. Maybe get some more design work added into the games, more features added to them. Seems fairly new too so no doubt going to need to promote it in order for your business and gambling site to succeed in the world of crpto. Maybe look at adding in multiple crypots as many want this and theirs not many casino or sites around accepting different types of coin. Maybe you could be the first to lead the way in adding lots different cryotp.
It would need a hard work for them to add altcoins since it is a moneypot app, did you even notice that they are moneypot app? Adding altcoins is not a guarantee that they will be better than now..
Regarding its design, I think their design is good enough in order just for playing. Not a high priority to be considered.
