Reversi: not every disc has equal value
Having more discs early can look like an advantage. In Reversi, position and available moves matter too.

A capture must be bracketed
A legal move traps one or more opposing discs between the new disc and another of your color. Lines can be horizontal, vertical or diagonal. If a move closes several lines, every resulting capture applies.
Why corners matter
A corner disc cannot be bracketed from beyond the board edge. It therefore stays stable for the rest of the game. Squares next to an empty corner may give the opponent access to it; check that possibility before playing there.
More flips do not always mean a better move
A move flipping many discs may also give your opponent several strong options. Early in the game, preserving mobility and restricting the opponent can be more useful than immediately increasing your disc count.
When a player cannot move
A player without legal moves passes automatically. The opponent continues. When neither player can move, the game ends even if empty squares remain, and the discs are counted.
Practice in two modes
Pausa’s computer uses a heuristic strategy considering positions, corners and mobility; it does not play perfectly. Two players lets you share the device and discuss decisions after a game.
