4 balls or 4 in a row is a fun game in which you have to beat your opponent by being the first to lay four pieces of the same colour in a consecutive line. You can play this game with two players. Each player takes a turn to put down one piece of their chosen colour. Can you block your opponent's attempts to form a line and complete one of your own? This classic skill game is a traditional favourite! Try out popular games like Gem Strike, or the classic naughts and crosses game Tic Tac Toe. Have fun!
