In Tan-tan Caravan, you play as an Arabian merchant trying to fill your caravan with the most valuable treasures. The game is a mix of strategy and luck, where you need to collect goods, avoid hungry mice, and gain favors from characters like the Princess and the Genie. On their turn, each player can buy cards from the market or stock the caravan. When the caravan is full, players must collect all cards of a specific type and display them to show off their riches. The game continues until the caravan is filled again and players have collected their cards. In the end, the player with the most points wins. With market and set collection mechanics, Tan-tan Caravan is a light and fun experience for 2 to 4 players.
