How to play Portal Billiards games
In this billiards game variant, pockets are not just pockets. These are Portals!
The game takes place in a space, sci-fi ambience, like if a billiard table was installed in a spaceship.
There are balls of two colors - the blue and the red ones.
Players should pocket balls into the portals with the respective color, the red into the red, the blue into the blue.
After every shot, the portals randomly change their positions in the pockets.
