How to play
Tap a ▼ button (or tap any slot in a column) to drop your gold disc — it falls to the lowest open slot.
Connect 4 in a row — horizontal, vertical, or diagonal — to win. A full grid with no winner is a draw.
The red AI moves after every turn. Easy looks 4 moves ahead, Medium 6, Hard 7 with full tactics (center control, threats, and blocks).
Tip: the center column is the strongest square on the board — and never let the AI sit on three in a row.

About Four in a Row
Four in a Row (the Connect 4 style game) is deceptively deep: drop discs into a seven-column grid and connect four before your opponent does. Our free online version plays against a real AI, so every game is a genuine tactical duel, not a coin flip.
The secret is playing two games at once — building your own threats while killing theirs. Center columns are the most valuable real estate, odd/even row parity decides endgames, and a well-placed forced win is one of the most satisfying feelings in casual gaming.
Quick tips
Play the center columns — they participate in the most possible fours.
Always block an immediate three-in-a-row, but look for your own double threats.
Think about who gets the bottom rows; parity often decides close games.
Frequently asked questions

Who goes first?
You do — and going first is a real advantage, so the AI plays to earn it back.
Can I play on my phone?
