The casual game for two to four espresso lovers!

Sit down with a perfectly drawn demitasse, and enjoy an fun and easy game of Caffe Primo with your friends. Add a tile showing chocolate and steamed milk to espresso and score a Mocha. Or, add milk froth instead to score a Macchiato. If you can create multiple beverages in a single play, you score them all! Not sure how to whip up a Con Panna? Not to worry; all of the recipes are displayed on your score card. Caffe Primo is a relaxing game that anyone can play!
