From the developer:
Pentaballs is like noughts and crosses, but it's better! Try to line up 5 marbles of your color while thwarting the plans of your opponent. Each move consists of placing a marble and then twisting one of the four game blocks. Continuous rotation of the blocks changes the game board and the player's tactics. Be careful! Your movements could also be beneficial to your opponent!
