A precursor to Bingo, Lotto utilizes cards showing pictures or numbers in a grid, commonly 4x4 pictures or 3x6 numbers. The same images or numbers are scattered on different cards. A set of tiles or small cards is used to call out which image/number the players should cover up with a chip. The first to get one row complete wins a round. Many people can play at once; one older game was designed for large groups of up to 48 players.
