Here are some different parts of the game. You can mouse over parts of the image at right and should see a pop-up with the name of that part.
Observatory Ring the bell in the observatory at the upper left of the table to start a mission.
Accelerator Hit the three targets above the whirlpool to activate the accelerator. When you hit the ball up the ramp towards the Treasure Chest the ball will accelerate with a whoosh sound, giving it enough speed to open the Treasure Chest.
