We are slowly starting to expand the number of medals in some of our oldest games. We have previously added fifth to eighth medals in Bingo Spinner, and now the turn has come for Bubble Zoo. The jump from the first four medals to the next four is very big, so these medals are especially made for the most loyal fans of the game. Can you score 2,000,000 points, or reach round 50? Then these medals are made just for you. Enjoy Bubble Zoo.
