Number of Players: 2
Setup/Board Description: Square Grid (such as graph paper.) The Top and Bottom edges are owned by Player 1, and the Left and Right edges are owned by Player 2. Corners are shared.
Suggested Board Sizes and Play Times:
15 min - 11x11
30 min - 16x16
60 min - 22x22
Each player tries to connect their two edges of the board by drawing dots and connecting them together.
* A player draws a dot in ANY empty square on the board.
* Then the player connects it (draws a line) to all of their adjacent dots in the eight adjoining squares, unless it would cross an opponent's connection.
Win condition: A player connects their two edges of the board.
Pie rule (optional, this rule nullifies the 1st player's inherent advantage): After the first move is made, the second player has one of two options:
1) Letting the move stand, in which case the second player remains the second player and moves immediately, or
2) Switching places, in which case the second player becomes the first-moving player, and the "new" second player then makes their "first" move. (I.e., the game proceeds from the opening move already made, but with roles reversed.)
Now the puzzle:
In the following 7x7 n00b game, Red moved at d3, then Blue at b4, then Red at d5. So it's Blue's turn to move. Is there any way:
1a) Blue can stop red from forming a connection between d3 and d5?
1b) If not, where should have Blue moved instead of b4 on their last turn?
2) Can Blue stop Red from winning the game at this point (i.e., has Red already won)?
