prediction-bot

This is a Discord bot to run predictions, inspired by the Twitch prediction system. When added to a server, mods can begin a prediction with the !question command. Users in the server can predict with their points, and a mod can pay-out when the result is given. Users will double their predicted points if they are correct.

This bot is written in Node.js with the discord.js module.

Commands

The commands available are split into two groups: those that anyone can perform (participating in the predictions), and those that only the moderators can perform (running the predictions).
