Our take on Zerko
Instead of using scores, timers, or escalating pressure as puzzle-game motivators, Zerko centers each board on cancellation: shaped pieces and values are arranged until every number reaches zero. This replaces performance tracking with a focused placement problem.
What is Zerko?
Zerko is a number puzzle built around shaped blocks and values.
The objective is to place pieces on a board so their numbers cancel out to zero. Its structure resembles reverse Sudoku or a nullification game, with strategy focused on choosing placements that remove the board’s remaining values. The game omits scoring and time limits, making each puzzle a calm exercise rather than a timed challenge. It has no data collection or advertising, and the vendor states that it contains no in-app purchases. Relaxing audio accompanies the puzzles. The vendor says additional content and levels may be added in the future, but those are presented as a plan rather than current features.
