An online addition pyramid game featuring Albert Einstein as your guide, in which you must fill in the blanks in the pyramid with the correct numbers so that the two numbers at the base add up to the number above them. This game helps you practice addition and subtraction while applying logic and reasoning to the rules of the number pyramid to figure out the missing number in each cell. To solve the pyramid, you’ll need to practice addition as well as subtraction—that is, inverse operations—using logical reasoning to determine the values of the unknowns. Two numbers in consecutive boxes on the same row must add up to the number in the box directly above both of them. Magic pyramids are triangular logic puzzles where the numbers on each level are related to those below by a rule—usually that each number is the sum of the two numbers below it. There are versions that involve subtraction, multiplication, or fractions, and they are widely used to practice mental math, logical thinking, and problem-solving in a visual and entertaining way. In addition to applying the rules of the game and adding and subtracting, this game encourages children to discover the best strategy for solving the puzzle in order, since some spaces are impossible to solve at first, while others are easier to solve—these are the ones that should be chosen first to fill in the pyramid. The more numbers that are solved, the more clues we’ll have to solve the remaining gaps. This strategy is similar to the one required in Sudoku, where the order of solving is a key factor.
