Connect Four
Drop your discs and be the first to line up four in a row â horizontally, vertically or diagonally. Play against a clever computer opponent or a friend on the same device.
About đ´ Connect Four
Connect Four is a timeless two-player strategy classic. Players take turns dropping coloured discs into a vertical seven-column, six-row grid. Because of gravity, each disc falls to the lowest available slot in the column you choose. The goal is simple to learn but tricky to master: be the first to line up four of your own discs in a straight line â horizontally, vertically or diagonally â while blocking your opponent from doing the same. This version lets you play against a computer opponent with three difficulty levels: Easy makes mostly random moves, Medium favours the centre and blocks obvious threats, and Hard looks ahead to avoid traps and set up its own winning lines. Prefer a human rival? Switch to 2-player mode and pass the device back and forth. Scores are tracked across rounds, so you can play a best-of series and see who comes out on top.
