If you are new, start with Kiki's tutorial. She will show you how to match the flower cards on the table with the ones in your hand. When you form a set, decide whether to 'Stop' and take your points or call 'Koi-Koi' to keep playing for a bigger score—but be careful, if your opponent scores before you finish, you get nothing!
The gameplay is a mix of set collection and risk management. Players must learn which cards are high-value and how to prevent their opponent from completing sets. The intuitive interface highlights possible matches, making it easy to focus on strategy rather than just rules.
Kiki's Koi-Koi is a single-player game where you play against the computer (Kiki), making it a great way to practice and learn the game.
