INTRODUCTION 2 puzzle grids and 4 difficulty levels to choose from. Challenge yourself by playing the Blitz mode (try to solve as many puzzles as possible in a fixed time) OR try to go on a solving streak (keep solving puzzles, each successful solve will reset the timer and show a new one. This continues till you fail to solve one). See your high scores on the leaderboard and challenge your friends! Measure your progress through achievements! The fun and entertainment never ends! GAME OBJECTIVE The objective of each puzzle is to find out the correct number(s) to fill-in all the empty squares in the Grid. A correct number “combination” should result (by either addition or multiplication) in the answer number(s) displayed in the Circles next to each row AND under each Column. The answer in each circle can be matched either by adding or multiplying the numbers in the same row or column together. This is done automatically by the puzzle and you don’t need to specifically select an arithmetic operator. All you need to do is to enter the correct number(s) and the puzzle will apply the addition or multiplication to all possible combinations for that row or column and try to check the result against the answers in the circles. CLUES: Depending on the selected difficulty level, you’ll see several squares automatically solved (containing numbers) when the puzzle loads. These clues will have a green square background. You only need to find the correct numbers for the remaining empty squares.
