About Zenku
Zenku is a number puzzle game built around filling a 4×5 grid. Each puzzle has a unique solution, with rules for the numbers in each row and column and in two colored sections.
You fill the grid with numbers from 1 to 5, making sure none repeat in a row or column. The numbers in each row must also add up to the result shown beside it, and both colored sections must contain all five numbers from 1 to 5. The game includes 100 puzzles and a YinYang mode, where you solve puzzles within 2 minutes.
