This game isn't actually playable, at least on my system. (G4 & 10.3.2)
I get the board with the grid of bubbles etc.
Every time i click on some bubbles one of 3 things happens:
1 - Some bubbles somewhere at the top disappear and i get some points.
2 - Some bubbles fill in some of the spaces at the top and i get some points.
3 - Nothing happens and i get some points.
I always get some points and i can keep clicking forever and getting a higher and higher score. Nothing really changes and the game never ends!
