MCGamble is a plugin that allows players to bet both against each other and against the house. Supports permissions.
mcgamble.* and OP status grant all commands. Case sensitive
/gamble help - shows a list of commands (mcgamble.help)
/gamble roll <max> - rolls a custom die with a set maximum and broadcasts the result. (mcgamble.roll)
/gamble hand - bets the items in your hand against the server. Higher than 60 (out of 100) wins. (mcgamble.hand)
Upcoming features: Ability for players to bet against each other directly in an automated way rather than relying on a dice roll and and a honor system.
Built against the spigot API version 1.8.8-R0.1 snapshot
