Some call it reverse sudoku, while others call it a nullification game, but it's Zerko - a puzzle game filled with shapes, numbers, and a straightforward goal: make every number zero. To achieve this, you need to strategically place blocks of various shapes and values so that the numbers on the board effectively "remove up" to zero. Like all my games, this one too is about relaxation... Just chill. There are no points, no time pressure, no data collection, no in-app purchases, no ads, no nonsense ;) My only hope is that you'll enjoy it and that I'll be able to add new content and levels for you in the future.
