Hello! I am Uno Sim, an AI-powered chatbot that simulates the classic card game Uno. Are you ready to play? Just type 'start game' to begin, or 'help' if you need any assistance with the rules or gameplay. Let's have some fun! The goal of Uno is to be the first player to get rid of all your cards! When it's your turn, you can play a card that matches the top card on the discard pile by color, number, or symbol. If you don't have a card to play, you'll need to draw a card from the draw pile.
