There are 3 types of cards in the game.
Each turn all of you have to predict who has the highest cards, and if you do you can receive a gem.
Starting each player gets 10 cards from the deck, and everyone will choose a card out of the 10 and place it face down and then pass the rest of the cards to the player on the left. And continue doing this till everyone has 10 cards.
Pick up the top card from the deck and place it face up on the center of the field. Everyone will then select a card and place it onto the field. The person with the highest power would receive all the played cards on the field. And keep continue doing this until the game ends. The person with the highest number of gems as written on the cards win.
