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.

Polygon Mayhem is a highly innovative and intellectually engaging puzzle game that challenges players with a wide variety of intricate levels — some of which are true brain teasers. At the heart of the gameplay lies a clever mechanic: solving spatial puzzles using simple geometric shapes like squares and triangles. Players must strategically place, rotate, and unfold (flip) parts of these shapes to fit perfectly within the puzzle frame. This elegant combination of geometry, logic, and creativity results in a unique gameplay experience that encourages out-of-the-box thinking and spatial reasoning. Whether you're solving a quick level or tackling a complex shape arrangement, Polygon Mayhem delivers a deeply satisfying puzzle-solving experience that’s both fun and mentally stimulating.
