5 stars: An intelligently designed application that not only teaches the basics of probability but challenges one's understanding of Probability. In case of failing to solve the puzzle, help is limited to hint and solution in not provided rapidly. Instead, through interesting and encouraging phrases one is motivated to find the right answer to the puzzle... Simply Brilliant...
5 stars: Having never taken a probability course, at any level, I find some of these very difficult, but very fun. I've literally spent days on some of them, not giving up until the a-ha hit. It's so rewarding to finally figure it out.. especially since the program taunts (and encourages) you.
3 stars: Great collection of probability puzzles with enough variation to keep even expert statisticians occupied for many hours. But please, can't we escape political posturing within the universal realm of mathematics? It's saddening that even math geeks are being overwhelmed by their own personality flaws.
4 stars: I like the game but have serious issues with the difficulty as it is totally inconsistent, in my view : at the easiest level you first have the Monty Hall problem and right after computing the probability of rolling a 7 with two dice ?!?
5 stars: awsome app... It helped me get back to probability again after a long while... thanks! Edit: how do I get a solution and explanation of solution if I am unable to solve a question even after reading the hint?
5 stars: Very good range ...
