This set of 100 cards, each of which includes a humorous, full-color drawing, promises "the world's best brainteaser questions." The characters in the questions often have funny names (Professor Pith Bugby pops up often) or faces or dilemmas to solve. The answers and explanations are on the back of each card, along with a related bonus question. Many of the puzzles involve math concepts, spatial reasoning, logic, or sequential thinking, but some can be solved with plain common sense. Here's a sample: "Frank and Helen's annual singles elimination tennis tournament has drawn 18 players this year. How many matches must be played before there is a winner for the year?" Answer: "Every match will produce one loser, and every person other than the winner will lose once and only once. Eighteen players makes 17 losers; therefore it will take 17 matches to have a tournament winner." Visual Brain Storms is a humorous, painless way to improve those higher-order thinking skills. Visual Brain Storms: The Smart Thinking Game is for one or more players.
