Challenge yourself with probability puzzles! Your brain will ♥ them, and they're excellent practice for technical interviews -- especially if you expect math or probability questions. With three difficulty levels to choose from, there's a puzzle here for everybody, from beginner to expert. You'll learn some probability and statistics, all while having fun -- even if you've never studied the subject formally.

Solving these puzzles will get you thinking about several powerful concepts in probability, including:

• independence
• expected value
• conditional probability and Bayes' rule
• linearity of expectation
• inclusion-exclusion

This app will be useful to anyone looking for probability exercises, brain teasers, or mathematical puzzles. Enjoy!

Simple and awesome! The problems are classic covering well known and popular puzzles. The hints are just enough to guide on the right track. The levels have been very well differentiated. Must for any math fanatic.

#### James Arruda

Challenging and fun problems that are a really great way to self-teach probability skills along the way!

#### Maxime Romano

Outstanding little game This is perfect for occasional small brain teasers! The puzzles are clear and the answers can be given flexibly! If I could give 6 stars I would.

Somehow tough but am getting my way through them. Just did the easy one the outrageous are Phd level questions.

#### Manik Jindal

The app is great and the questions are fantastic. The difficulty level builds gradually with ever passing question and reinforces learning. One thing I'd request the developer is, that make the solutions available. Sometimes I am stuck for days and cant wrap my head around the problem even with the hint. A simple solution would really help me learn more. Kudos!

#### George Davinci

Many thanks for this wonderful app. I would enjoy it even more if there could be more than one hint per puzzle, at least for the hard ones ;) Thanks again :)

#### Alixe Leclercq

Really well made and fun Love the fact that the app doesn't give you the answer, just hints. The person behind this app must be awesome. Some of the questions and writing are really funny :-).

#### Andrew Stuckey

Good Practice The problems increase in difficulty and the warm ups are good practice for the more complex ones.

#### Elijah Coleman

Better than class I do this instead of paying attention in stats. It gets legitimately complicated.

#### Maxim Razin

Just wow! The interface is pretty simplistic but you can enter expressions as your answers, not just numbers

#### Rod Sanchez

Good Nice to see an approach that differs from usual gamefied rewards, prizes, bonus, blah blah.

Probability Puzzles Candy for the mind!
