Pathwayz (2014)

The goal? Build a path in your color across the long side of the board... before your opponent. Each turn, you can place a double-sided piece in your color OR a permanent piece in your opponent’s color. Why would you give your opponent a permanent piece? Because doing so flips the touching pieces, allowing you to dynamically alter the game. The first player to connect opposite ends wins.

Louis Lafair invented Pathwayz when he was 11 years old.
