Neon Reversi guide: legal moves, corners and mobility
How a legal move works
Place a disc on an empty square only when it brackets at least one opposing disc between the new disc and another of your color. Bracketing can happen horizontally, vertically, or diagonally, and one placement may flip several directions at once. The highlighted cells show every legal option for the current turn.
Turn order and the end of the game
Black moves first. If the current player has no legal move, the turn passes automatically. The game ends when neither color can move, usually when the board is full. The color with more discs wins; equal totals produce a draw. The counter above the board updates after each placement.
Why corners matter
A corner can never be outflanked, so a disc placed there remains stable for the rest of the game and can help secure an entire edge. Squares directly beside an empty corner are risky because they may give the opponent access to it. Sometimes accepting fewer immediate flips is the better long-term choice.
Mobility before disc count
- Early in the game, prefer moves that leave the opponent few legal replies.
- Avoid filling the edges carelessly when a corner is still open.
- Count the opponent's possible moves, not only the discs you flip now.
- Near the end, calculate the remaining empty squares and plan the move order.
Playing the computer or a friend
VS AI uses a straightforward opponent: it takes a legal corner whenever one is available; otherwise it prefers the move that flips the most discs. This makes it approachable for learning the rules, but it can be beaten by prioritizing mobility and corner control. Two-player mode keeps both colors on the same device and applies identical legal-move highlighting.
