The rules are simple-
If you have a water sign (Cancer, Scorpio, Pisces) or an earth sign (Capricorn, Taurus, Virgo), add 1.
If you have a fire sign (Aries, Leo, Saggitarius) or an air sign (Gemini, Libra, Aquarius), subtract 1.
Every round starts at 15 points. If it gets to 30, earth/water signs win. If it gets to 0, air/fire signs win. Work together with your signs to win!
