- These are the "European Standard" for mini cards. This is actually the MOST common mini-card size in the board game industry. We recommend keeping an extra pack of these around as they are just so darn useful! These fit literally hundreds of games including 7 Wonders Dual, Arkadia, Big Boss, Briefcase, Camel Up, Catacombs, Chinatown, Codenames, Cuba, Dungeon Lords, El Grande, Endeavor, Fresco, Goa, Islebound, Macao, Mysterium, Pillars of the Earth, St. Petersburg, Scoville, Shogun, Thebes, Ticket To Ride USA and Wings of War and many more!
