Prof Marbles

Prof. Marbles provides players with more than 50 challenges in 4 different levels of difficulty. Each challenge card shows the set-up and the required outcome of the lab experiment: which test tubes do you have to use for this challenge? how many colored balls do you need? and in what order are the balls sitting in the test tubes? by cleverly transferring the balls from one tube to another, you can rearrange the order of the balls. The objective is to arrive at the stipulated color combination with as few ball transfers as possible. The challenges become increasingly difficult, and experimenting with the balls and tubes gets more and more demanding. Prof. Marbles is pure logic from the lab!
