=== Object of the Game ===
Be the first player to fill a row, column, or diagonal with 4 stones.
=== Setting Up the Game === First select the options on the right-hand side of the screen. Below is an explanation of the controls:
==== Type ====
Select the type of player. A player can be a human or a computer. You can play against a friend or the computer. You can even watch the computer play itself!
==== Skill ====
If this player's type is "Computer," this option sets the skill level of the computer's Artificial Intelligence. (Don't be disappointed if you cannot beat the computer at the hardest setting—it's impossible!)
=== How to Play ===
Black is the first player to take a turn.
The very first turn consists of only one move. Player 1 (black) gets to place a stone anywhere on the board.
For the next turn, Player 2 (white) gets to place 2 stones on the board. If Player 2 completes a pair of symbols, he/she can remove Player 1's stone from the board.
All subsequent turns are like Player 2's first turn and follow this pattern:
The current player places a stone on the board.
If the symbol on the board position just played matches a symbol under any of the current player's other stones, he/she must immediately remove a stone from the other player.
The current player places a second stone on the board. If the current player completes a second pair of symbols, he/she removes another stone from the other player.
The game ends when either:
A player completes an entire row, column, or diagonal with 4 stones. It is impossible for the current player to move (a tie).
