These short interactive mysteries are examples of lateral thinking puzzles. Each puzzle describes an unusual scenario, and your job is to figure out what is going on. 
Brain Teasers show how our preconceived notions, combined with the brain’s tendency to see what it wants or expects to see, greatly affect how we solve problems and make decisions. :rolleyes:
You can find many games like abalone, chain reaction, follow me, 2048 and reaction.
