Put the phone between both players and turn it into a Connect Four board. Each person taps a column in turn; counters drop, every line stays visible and nobody needs a second device.
Frequently asked questions
How does a turn work on the same phone?
The current player's name appears above the board. They tap an available column, then the turn passes automatically to the other player.
Does the game detect diagonal lines?
Yes. A win is detected as soon as four matching counters line up horizontally, vertically or diagonally.
