Orochi

Orochi is a connection game with a somewhat quirky goal.

Each player is in charge of one of the two colors, but can also place a piece of the opponent's color through the game. If, after your placement, there is a piece adjacent to a stone of the same color in four directions, you may exchange that piece for a piece of the opposite color and get an additional turn.

Play until there is only one space left on the board, and the player with the larger group adjacent to the last space wins.

This game is included in Generic Board "Hexagonal" set.
