Think about sudoku, but reinvented! This game has just a few simple rules: You have to fill a 4x5 grid with numbers from 1 to 5, ensuring that each row and column won't have duplicates and that the sum of each rowโ€™s numbers gives the result on their right side. Also, you must insert all five numbers (1,2,3,4,5) into the two colored sections on the grid. Each puzzle has a unique solution. It's relaxing, but still pretty challenging. If you want to spice up the challenge, play โ€ข zenku โ€ข in YinYang mode and complete the puzzles within 2 minutes! The first 50 levels are free, with some ads here and there in case you'll ask for a hint (bulb button). You can unlock extra 50 levels and remove ads with a single In-App purchase. Will you complete all the 100 zenku puzzles? _________________________________ Frank Eno (aka XSGames) is an indie game dev from Italy.
