Reversi Game Guide

📖 About

Reversi (also known as Othello) is a classic strategy board game of territory and capture! Place discs to outflank and flip your opponent's pieces to your color. The rules are simple—sandwich opponent discs between your own to capture them—but the strategy runs deep. At game's end, the player with more discs wins. Easy to learn, difficult to master, Reversi offers endless tactical challenge!

🎯 Objectives

End the game with more discs of your color than your opponent. Maximize your disc count by planning moves that flip multiple opponent discs while protecting your own from counter-flips.

🎮 How to Play

Click on a valid cell to place your disc. You must flip at least one opponent disc. Discs are flipped when sandwiched between your discs. Game ends when no moves remain.

⌨️ Controls

Click on any highlighted valid move to place your disc. Valid moves must outflank at least one opponent disc. Outflanked discs are flipped to your color.

⚙️ Game Mechanics

  • Focus on stable discs that can't be flipped
  • Mobility matters - keep your move options open

Frequently Asked Questions

What are corners so important?
Corner discs can never be flipped because they can't be outflanked. Controlling corners often leads to controlling the adjacent edges, creating stable positions.
Is having more discs early good?
Not necessarily! Early game disc count matters less than position. Sometimes having fewer discs means more mobility and better moves later.
What's a 'stable disc'?
A stable disc is one that can never be flipped regardless of future play. Corner discs are always stable, and discs adjacent to stable discs often become stable too.
When does the game end?
The game ends when neither player can make a valid move—usually when the board is full, but sometimes earlier if no flips are possible.
