⚫ Othello
Tap a highlighted square to place your disc — every enemy disc you bracket flips to your colour.
How to play
Othello (also known as Reversi) is played on an 8×8 board that starts with four discs in the centre — two black, two white. You are Black and you always move first. A move consists of placing one of your discs on an empty square so that it brackets at least one enemy disc in a straight line: horizontally, vertically or diagonally, with one of your discs already sitting at the other end. Every bracketed disc flips to your colour. You cannot place a disc where it flips nothing — and if you have no legal move at all, your turn is skipped automatically and the computer moves again. The game ends when neither side has a legal move; the player with the most discs on the board wins, and equal counts mean a draw. It is the famous “minute to learn, lifetime to master” game: early leads count for almost nothing, and the final ten moves decide everything.
Controls
- Mouse / touch: tap any highlighted square to place your disc. Legal moves glow as small dots — use the Hints button to turn the guides on or off.
- Turn flow: after your move the computer replies automatically. If you have no legal move, the game tells you your turn was skipped and the computer plays again — no pass button needed.
- New Game resets the board to the classic four-disc starting position with you to move.
Tips & strategy
- Corners are everything. A disc in a corner can never be flipped back, so work toward the corners — and avoid giving the computer the squares next to a corner (the diagonal adjacent squares are traps that hand corners away).
- Don't chase early disc count. Grabbing every disc you can in the opening gives the computer more of your discs to flip later. Play quiet, low-flip moves and keep the board fluid.
- Limit the computer's options. Fewer open squares near its discs means fewer replies — force it to play where you want it to play.
- Mobility beats material. Having a legal move every turn (not being forced to skip) is often stronger than leading 20–10 in discs mid-game.
Scoring
There are no points for style — the only score is the disc count shown in the HUD. Finish with more discs than the CPU and you win; finish tied and it's a draw. The end overlay announces the final tally and the result, with a one-click Play Again to chase the rematch.
