Rotodo

From BoardGameGeek:

"A two player strategic node superiority game" Rotate a square of 4 pieces on the board using a unique magnetic component. The goal is also rather unique as two conditions must be met: 1. "Isolate" your opponent's "main node" by surrounding it with your own nodes (or pieces). And... 2. "Connect" your "main node" with your opponent's "main node". You may not rotate the exact nodes that were rotated on your opponent's previous turn. Some variable setups allow the game to be customized. "Rotodo, das Spiel mit dem Dreh! Hast du den Dreh raus? Dann komm auf die andere Seite und zeig deinem Gegner wo's lang geht!"
