How to Play Reversi
Reversi is a board game where Black and White take turns placing discs. Trap your opponent’s discs between two of yours and they all flip to your colour. When the board is full or neither side can move, the player with more discs wins.
How to play Flow
1
Black moves first. The game starts with two black and two white discs in the centre.
2
You may only play where you trap at least one opposing disc vertically, horizontally or diagonally. Legal moves are marked with a lime dot.
3
Every trapped disc flips to your colour — you can trap in several directions at once.
4
With no legal move you pass automatically. When neither side can move the game ends, and the most discs wins.
Controls Controls
- Place a disc
- Tap or click a square with a lime dot.

- Against the CPU you can play Black (first) or White (second).
- Undo
- Against the CPU it takes you back to your previous move; in 2P mode it undoes one move at a time.
Strategy tips Tips
- Corners can never be flipped once taken — they are the strongest squares. Grab them whenever you can.
- The squares diagonally next to a corner tend to hand the corner to your opponent. Avoid them early on.
- Limiting your opponent’s options matters more than flipping lots of discs early. The count can swing at the end.
- Edges lead to corners. Once you own a corner, build solidly along its edges.
