In Ligretto, everyone plays at the same time, attempting to discard as many cards as possible to the communal piles in ascending order. One box allows you to play with 2-4 players. Add a second different colour box and up to eight can play, add the third and now twelve players can compete. Easy to learn, this fun game is played at breakneck speed. Ages 6+, allow 10 minutes per game.
