Line up four stones across, down or diagonally. First to four takes it.

How many players

Played by 1 or 2: solo against the computer, or online against another player.

Online: create a room and send the link to a friend, or get matched with a random opponent. If nobody shows up, we offer a clearly labeled computer opponent.

Goal: First to line up four stones across, down or diagonally wins.

The board has 7 columns and 6 rows. You take turns dropping one stone at a time.
Tap a column: your stone falls to the lowest empty spot in it.
First to get four in a horizontal, vertical or diagonal line wins.
If the board fills up and nobody makes four, it is a draw.
Each new round, the first move switches to the other side.

You can’t drop into a full column. Pick another one.
Bot levels: Easy mostly plays at random and sometimes misses a win or a threat. Medium always takes a win and always blocks a threat. Hard thinks several moves ahead.

Touch: Tap a column, or slide your finger across the columns; the stone drops where you lift your finger.
Keyboard: Keys 1–7 pick a column. In solo play, Enter or Space starts a new round once one ends.

You have 60 seconds per move; run out and you lose.
If you disconnect, you have 60 seconds to come back or your opponent wins. Leaving the game also hands them the win.
A rematch needs both of you to say yes; the first move switches sides in the rematch.

Opponent has three in a row? Block it right now.
The middle column is part of the most possible fours, so keep your stones near the center.

Vanishing XOX: You only get 3 marks. Place a new one and your oldest vanishes.
Admiral Down: Hide your ships and send your rival's fleet to the bottom before they get yours.
Backgammon: Your dice, your tactics. Bear off first and gammon them before they gammon you.
Mangala: Sow stones pit by pit, then raid your rival’s treasure with the last one.
Turkish Checkers: Pieces move forward and sideways, and capturing is a must. Crown a king and sweep the board.
Nine Stones: Line up three, steal a stone. Whoever drops to two is out.
