Our Four-in-a-Row is part of Game Index’s Stop Dementia series. The rules to this classic game are easy―just remember that you need to work from the bottom up. The arrows show you where you can place your chip. Simply get four in a row, either horizontally, vertically, or diagonally, and you win! You can play against the computer, and choose whether you want to go first or second. You can also play with a friend. This series is not just for seniors—it’s also great fun for younger people.
