Reversi is played on an 8×8 board with 64 squares
One player uses black discs and the other uses white discs
The game starts with four discs in the center in a diagonal pattern: two black and two white
Black usually moves first
On your turn, place one disc on an empty square
Your placed disc must trap one or more of the opponent’s discs in a straight line
A line can be horizontal, vertical, or diagonal
The trapped opponent discs are flipped to your color
You must flip at least one opponent disc to make a legal move
If you cannot make a legal move, you pass your turn
The game continues with players alternating turns
You may choose any legal move available on your turn
The game ends when neither player can make a legal move
The player with more discs of their color on the board wins
If both players have the same number of discs, the game is a draw
