There should be twelve completely different colors represented by four players. 

Each player has three different colored marbles for values 1, 2, and 3. 

Each player places a different colored marble in the 1, 2, 3, top holding cave on the side. 

For the bottom row, place three marbles in the 1 slots, two in the 2 slots, and one in the 3 slot. 

The bottom row marbles should match the colors of the top row. 

Player 1 is chosen, and player turns go clockwise. 

Each player may choose any marble from the bottom row to play.

Within their quadrant, each player rolls one marble. 

Each roll must make at least one full circle. 

Play continues until all players have rolled all marbles from their bottom row. 

All marbles are left in place and the game is scored.

If a tie for first place exists, all marbles are left in place.

Play resumes using marbles from using top row marbles. 

After all marbles have been played, the game is rescored.

First, count the top of the board. 

Your marble's value is multiplied by the number in the slot in which it landed. 

That score is both added to the marble owner's tab, and deducted from the slot owner's tab. 

Next, the bottom tray is counted.

The value of each marble in a player's + cup is added to the cup owner, and subtracted from the marble's owner. 

The value of each marble in a player's - cup is subtracted from the cup owner, and added to the marble owner. 

The highest score wins.
