Sixteen - multiplayer puzzle

New Dark Mode!

Sixteen is a two-player numbers duel built on one simple goal. Take turns placing tiles on the board and be the first to make four in a row that adds up to exactly 16. Across, down, or diagonally. That's it. The catch is that your opponent is going for the same thing, so every move is part offense, part defense.

If you've played tic-tac-toe or Connect Four, you already get the idea. Sixteen takes that feeling and gives it real depth. There's no luck and no dice. Just you, your opponent, and the better plan.

What makes it click:

Real opponents, right now. Get matched with a live player in seconds and start playing.

Short games that pull you back in. A full match fits into a coffee break, and the rematch button is right there when it ends.

Pure strategy. No power-ups, no randomness. You win because you outthought the other player.

Simple to start. Place a tile, build toward four in a row that sums to 16, win. You'll understand it in one game.

Room to grow. Play it tight on a 4x4 board or open things up on larger boards when you want more space to maneuver.

Practice on your own time. Sharpen your tactics against the computer before you take on the world.

A record worth chasing. Every win counts, and the good players climb.

How it works:

On your turn, pick a numbered tile and drop it on an open cell. Your job is to complete a line of four cells, in a row, a column, or a diagonal, where the numbers total exactly 16. First one there wins the round. The real game is reading what your opponent is setting up and shutting it down before they get there.

It's just numbers on a grid, but every move is a decision. Download Sixteen and find out who actually thinks faster.
