Your task is simple: Find a way to make Adsumudi's answer (the number in the center of each card) by using the other numbers on the card and any combination of addition, subtraction, multiplication and division. To make Adsumudi's answer, you can use any two numbers (that’s easy mode), three numbers (medium mode), four numbers (getting harder!), or for true math masters, you can use all five numbers (we call that monstrously hard mode). Each card can be played at different levels simultaneously or gradually. Work together to solve each level as you go, from easy mode all the way up to monstrously hard. Or for a little family-friendly competition, let kids of different ages play at their own level within the same game. When a card is revealed, everyone simultaneously tries to come up with the answer displayed in the middle of the card by adding, subtracting, multiplying, or dividing a combination of the five numbers displayed around the answer number. The first person to figure out a solution says, "Adsumudi!" They then share the solution they found. If it checks out they take the card. The first player to collect five cards wins. —description from the publisher
