Tap a column to drop a red disc.
How to play
- You drop red discs; the computer drops yellow ones.
- Tap a column to drop your disc — it falls to the lowest open slot.
- Line up four of your discs in a row — horizontally, vertically, or diagonally — to win.
- Choose Easy for a casual game or Hard for a sharper computer opponent.
Strategy & tips
- Play the centre column early — it is part of the most possible four-in-a-rows.
- Watch for the computer getting three in a row and block it before it connects the fourth.
- Set up a "double threat" — two ways to win at once — so a single block cannot stop you.
- Think about diagonals; they are the easiest wins to miss on both sides.
- Do not stack straight up unless it helps — you may be handing the square above to your opponent.
