Reversi Free online game

What is it?

Reversi is a board game where any opponent discs trapped between two of yours flip to your color. It has been played around the world for a long time.

You can only play where you'll flip at least one disc, and legal moves are marked with dots. Whoever has more discs at the end wins, but since a single move can flip many discs at once, having more in the middle game doesn't mean you'll stay ahead. Black moves first; against the AI you can choose Black or White.

How to play

1. You can only play on squares marked with a dot
2. Every enemy disc caught between yours flips to your color
3. When no moves are left, the player with more discs wins. Corners are key!

Difficulty and rankings

There's a weekly ranking and an all-time ranking; the weekly one resets every Monday at midnight (Korea time). For details, see the Help.

Good to know on Hanpanmadang

• If you have no legal move, your turn passes automatically. When neither player can move, the game ends even if the board isn't full; equal discs is a draw.
• Online, each move must be made within 40 seconds or you lose.

Common mistakes

Always playing the move that flips the most from the start.

More discs on the board give your opponent more moves too. Early on, flipping fewer discs and keeping your own options open is better.

Playing next to a corner first.

As in the example above, squares next to a corner easily give the corner away. Only play there when you already own that corner.

Tips

• Once taken, the four corners can never be flipped back. Whoever grabs corners first gains a big advantage.
• Be careful about playing right next to a corner (especially diagonally), as it tends to give the corner to your opponent.
• In the opening, it's better to flip few discs and keep many squares available to yourself than to flip a lot.
• Leave your opponent with no legal move and they must pass. Aim for this in the endgame.
