The 99 Effect for Mac

You're ready to become a full fledged scientist, but there is one more test you have to complete: Dr. Fill's Mixing Test. You will have to go head to head with Dr. Fill and force him to go over 99, which is the critical mixing point.

You will report to Dr. Fill's lab, where Mixie will help you get situated. You will have control of 7 jars of fluid. Each fluid will have a different effect on the center Beaker. Click the red buttons to add the jar's fluid to the Beaker. Dr. Fill will then add his fluid.

Add the "numbered" jars early, until you get close to 99. Then be careful, because one wrong move could send the Beaker over 99 and you will lose. You will have to be cunning and patient to force Dr. Fill to go over 99. He saves all his special jars until the very end.
