The best sites to play Reversi online for free include dedicated platforms, browser games, and mobile apps. Here are the top options compared by features, player base, and ease of use.

Reversi (also known as Othello) is one of the most elegant strategy games ever created — simple rules on an 8×8 board that produce deep tactical complexity. Every move can flip the balance of power, and the endgame often produces dramatic reversals.

Whether you’re a casual player or studying opening theory, finding the right platform to play online matters. We tested every major site offering free Reversi in 2026. Here’s where to play.

Reversi vs Othello — What’s the Difference?

Most online platforms use these names interchangeably, but there is a subtle difference:

Feature Classic Reversi Othello
Starting position Variable Fixed (4 pieces in center)
First move Either player Black always goes first
Board 8×8 8×8
Trademark Public domain Trademarked

In practice, almost every online implementation uses Othello rules regardless of what they call the game. The fixed starting position is standard everywhere.
