Puissance 4
Connect four before your opponent. Racing, action, puzzles and duels to enjoy on phones or computers.
On the board of 7 columns and 6 rows, connect four of your discs horizontally, vertically or diagonally before your opponent. Each player drops one disc per turn. A full board without four connected is a draw: retry this chapter. Tap or click a column or the board to drop a disc immediately. Gravity takes the disc to the lowest empty cell; the preview shows where it will land. You cannot play a full column. With keyboard focus on the board, arrows or keys 1–7 select a column; Enter drops the selected disc. Tab moves between controls; Space selects a column or activates the focused button. There is no turn countdown. The solo journey has 12 chapters. A new journey starts at chapter 1; win to unlock the next chapter. A loss or draw unlocks nothing: retry. Previously earned chapters stay available. Two players on this device does not unlock the campaign. Resume restores a valid saved game. Every robot sees the same board as you. It takes an immediate win or blocks an immediate loss, then examines a bounded number of moves for its chapter. Its preferences vary; neither perfect play nor strictly increasing difficulty is promised.
