Connect Four: One on One

A vertical grid waits between two rivals. In Connect Four: One on One, red and black discs stack inside a 7-by-6 board, with both sides chasing an unbroken row of four. Player names can be entered before the round, or left unchanged if chip color is enough to tell both sides apart. Head-to-head play only.

How to play?

Drop a disc into any column and watch it settle into the lowest empty space. Players alternate moves until four matching pieces line up across a row, down a column, or on a diagonal. Arrow selection is available for faster column choice during repeated matches. Another round begins right after the last one ends.
