Everyone has hearts - cards discarded!
Ali led with 10♥. Everyone followed suit (played hearts), so all cards are discarded forever. Priya had the highest (King), so she leads next.
You have no diamonds - dump any card!
Ali led with A♦. You have no diamonds, so you throw any card - this is a "Thulaa"! Ali had the highest diamond, so he must pick up all 4 cards. Ouch!
Last person with cards loses
Sara plays her last card 5♥, you match with 10♥. Both cards discarded, but you still have 1 card left = you're the PABHO!
Player with A♠ leads first
Must play same suit if you have it
Play any card - winner picks up all
