Pick a mode from Game Mode: Human vs Human (two players share the screen), Human vs AI (choose your color and an AI difficulty), or AI vs AI (set a difficulty for each side and watch). Press New Game to start. Black always moves first.
Undo takes back your last move (and the AI's reply when playing the computer).Hint outlines a strong move in gold for a moment.Black moves first, then turns alternate. If you have no legal move, your turn is automatically passed and the status bar announces it.
A move is legal only if the new disc outflanks at least one enemy disc: a straight line (horizontal, vertical, or diagonal) of enemy discs must sit between your new disc and another disc of your color. All outflanked discs immediately flip to your color.
Your score is simply the number of discs of your color on the board, shown live in the side panel scorecards.
The game ends when neither player has a legal move (usually when the board is full). The player with more discs wins.
Fewer discs at the end means a loss; equal counts are a draw. The result panel shows the final count.
There is no save feature — games are short. Press New Game at any time to restart, or use Undo to step backwards instead of restarting.
