I'd say some of the best features to add on to bare-bones dice would have to be as follow.
1. Some sort of chat system so the players who are gambling can all interact, which promotes the growth of some sort of community.
2. Sections that can show the high rollers betting and everything along those lines, as it's always fun to see someone bet with an insane amount of bitcoins and win. Promotes more betting on the site itself.
3. Leader-board is a must these days so you must include the biggest winners for the day, week, month, etc. Luckiest bets and so on. Again, it promotes betting due to highlighting the winners.
4. Faucets are good to add but I personally don't know if they promote more REAL betting on the site (people depositing more money onto the site) and it may just lead to people screwing around with the facuet money.
Good luck with the gambling site man, I'll be watching this thread.
1. The site actually does have a chat which serves it purpose well enough
2. Would it be better to have recent high roller bets or players can set a minimum bet (for example: only see bets over 1BTC)?
3. Leaderboard will be added to the code soon and if I do end up finishing the site in a timely manner, I will have wager contests as well.
4. Faucets and Buckets (Site maker's own customizable faucets) are now possible to make in the MoneyPot Api v2, and I think I will have faucet, since I will probably have atleast one game that is not dice. The games I'm developing right now are a bit hard to make in code, since they are only designed to be played offline. But will see about this!
