`don`: Play a "Double-or-Nothing" game.

    **Usage:**
        `don` by itself: Play the game!
        `don stats`: Show your stats for the game.

    The game costs $10 to play, and this $10 acts as the initial pot. You can
    choose to risk doubling the pot, or walk away with the current pot. If
    you succeeded in doubling the pot, you get to decide again. If you fail,
    the whole contents of the pot will be lost!

    The game is controlled by a system of reactions. If you need to refresh the
    game if you, say, played the game in another channel and are returning to
    the older embed, react with 🔄.
