HOW DO TWO PEOPLE PLAY HERE?

Choose 2 players and take turns on the same screen. Black goes first, white follows and the board checks every placement. This mode is local play on one shared device; it does not connect two separate browsers.

Make a little room at the board.

Decide who is black and who is white before you begin. Black always makes the first move from the standard four-disc setup. The highlighted score panel and turn message show whose move comes next. On a phone, pass the device between turns; on a larger screen, sit together and use a mouse or touch.

Othello has no hidden pieces or private hand, so both players can see the entire position. Our game does not use a timer. Take a moment to explain a capture, think through a reply or talk about the position. For a fair casual match, agree on whether you both want hints and takebacks before starting.

One placement, every captured line.

A legal move places one disc on an empty square and traps at least one opposing disc in a continuous straight line. The line must end with a disc of your own color. All lines captured by the new placement flip. You cannot place on an occupied square or pass when a legal move exists.

If one player has no legal move, the game passes automatically and the other player moves again. When neither side can move, count the discs: more of your color wins, and equal counts make a draw. Empty squares may remain at the end. See the full Othello rules for an illustrated example.

Simple controls for a shared screen.

Show moves marks legal placements for the current color. The small marker on a disc identifies the last move. Undo takes back exactly one placement in two-player mode, allowing you to revisit a position together. New game asks for confirmation before resetting a game that has started.

You can also use a keyboard. Tab into the board, use the arrow keys to choose a square and press Enter or Space to play. Home and End move to the start or end of the row. The square label gives its coordinate and tells you whether a placement is legal.

The shared game saves locally when browser storage is available. Returning to this page on the same browser can restore the position. Saved play is not synchronized between people or devices, and clearing browser storage removes it. See the privacy notice for details.

What about playing on separate devices?

This version has no online rooms, friend links, ranked matchmaking or live remote multiplayer. Sending someone this page shares the game website, rather than a synchronized match. For practice by yourself, switch to the computer opponent.

After a match, swap colors and start a fresh board. If one of you is learning, focus on a single idea from our beginner strategy guide, such as protecting empty corners, and compare what you both noticed.
