Common Questions
Is Reversi the same as Othello?
The names are often used for the same style of 8-by-8 flipping game. This online version uses the familiar modern opening and scoring rules.
Why can I only click certain empty squares?
Only legal moves are enabled. A legal move must flank at least one opposing disc in a row, column, or diagonal.
Can I pass whenever I want?
No. Passing is only allowed when you have no legal move. The app handles forced passes automatically.
What do the AI levels change?
Easy sometimes chooses casual moves, Medium values corners and mobility, and Hard adds extra pressure around frontier discs and opponent replies.
Can two people play on one device?
Yes. Switch from AI to 2P to play local two-player Reversi on the same screen.
How is the winner decided?
When neither player can move, the game counts black and white discs. The higher count wins; equal counts are a draw.
Why did a disc flip in more than one direction?
A move can capture several lines at once. Every unbroken line of opposing discs bracketed by your new disc and an existing disc flips.
What is the best beginner tip?
Do not focus only on how many discs you flip. Corners, mobility, and avoiding risky squares near empty corners usually matter more.
