Acardoo is for those evenings when you are all sitting together and nobody knows what to do. Put one phone in the middle and the first round is already running. Bluffing, guessing, drawing, estimating, reacting fast. There is something for every mood. Some rounds take two minutes, some take the whole evening. ONE PHONE IS ENOUGH No account and no connection. You just pass the phone around, that was the entire setup. Works at the kitchen table just as well as on a train or around a campfire. ONLINE WITH FRIENDS Not sitting at the same table? Open a lobby, share the code and everyone joins from home. Most games can be played online against each other too, live and in real time. Add friends by username or QR code. You can see who is online and pull them straight into your round with one tap. And when nobody is free, quick match finds players for you. Acardoo speaks German, English, Dutch, French, Spanish, Italian, Turkish and Russian. New games are added regularly. ACARDOO+ Play without ads and unlock exclusive content. The subscription runs weekly, monthly or yearly, prices are shown in the app. It renews automatically unless you cancel at least 24 hours before it ends in your Apple settings.
