It’s time to put your thinking cap on! Calculate Genius is a fast and furious observation-based puzzle game where you have to calculate the answers to a series of mini-puzzles in a super-fast time. There’s no chance to scribble notes or punch numbers into a calculator, you just have to use your math calculation abilities (quick guesswork) to succeed. Each mini-puzzle has a certain element of math and estimation to it, and you score points for getting as close to the correct answer as possible.

This fast-paced brain teaser will really test your observation skills, as you only have a few seconds to process the information in each mini-puzzle. Your fast calculation ability will be exercised, as some of the puzzles require adding, subtraction, multiplication and other math skills. This fun educational game is ideal for anyone who enjoys problem-solving activities, and all the family to play together. Are you ready to put your quick brain to the test? Good luck!

How to Play: In each game, you are presented with 5 random mini-puzzles. At the start of each mini-puzzle, you receive a question. For example, you might be asked: ‘How many times doesthe ball bounce?’ You will be then shown a short animation where a ballis quickly bouncing around a box. After the animation, you have to type in theanswer/estimate you think is correct into the box in the center of the gamescreen. Then hit the Return Key on your computer keyboard or click ‘Next’ with your mouse. You see your points score for that minipuzzle, before moving onto the next one. At the end of 5 puzzles, your overall score is shown. Keep replaying to see if you can increase your high score– NAN points is the highest you canachieve.
