About Drop Four: Disc Duel
Drop Four: Disc Duel is the vertical line-up game everyone knows from the toy cupboard, rebuilt as a glossy 3D tabletop set. A blue plastic rack with seven columns and six rows stands on the table; you and your opponent take turns dropping red and yellow discs into the top of any column, and each disc falls all the way down to the lowest free hole. The first player to line up four of their colour across, up and down, or diagonally wins the round. It takes seconds to learn and rewards real planning: build threats on two levels, use the centre column, and trap your rival into blocking in the wrong place. Discs tumble down with real gravity, bounce, and clack into place, and the winning four light up with a golden bar. Hover over a column to see exactly where your disc will land. Play the computer right away: Easy is relaxed and makes mistakes, Medium always blocks, and Hard searches eight moves ahead and almost never loses. Helpers include unlimited undo, a hint button, and a red warning on any column where the AI could win next turn. Sign in to play friends or quick matches online.
