The game

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 row’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 • zenku • 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?
