Portal Billiards play online

Rules:
In this billiards game variant, pockets are not just pockets. These are Portals!
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.
If a player pockets a ball into the correct portal, the player gets 3 points.
Otherwise, if a player pockets a ball into the incorrect portal, the opponent gets 3 points.
If there is no collision between the cue ball and any object balls, the opponent gets 1 point.
If the cue ball pocketed into any portal, it appears at a random position of the start area, and the next shot goes to the opponent.
If all balls are pocketed, the player with more points wins.
If the score is equal, the additional red ball appears at the start position to play.
