ZERO_FILL

A minimalistic puzzle game, where you need to apply a cross-shaped tile to add or subtract numbers from the board (riddled with holes) to achieve net zero within a limited number of turns. Very basic graphics (almost 80s aesthetics) accompanied by subdued but pleasant music, total 90 boards with growing difficulty to clear, and available generator of random boards once you clear all in the base game. If you’re into numerical puzzles, be sure to give this one a try.

ZERO_FILL is a logic-focused puzzle game developed and published by Catoio Software. Built around a simple but surprisingly clever concept, the game challenges players to reduce every numbered tile on a grid to zero. What initially appears to be an easy task quickly evolves into a thoughtful exercise in planning, pattern recognition, and strategic decision-making. The core mechanic revolves around interacting with tiles that influence surrounding spaces, forcing players to think several moves ahead rather than relying on trial and error. One of the game's strongest qualities is its commitment to minimalist design. Instead of distracting players with elaborate visuals, story elements, or unnecessary mechanics, ZERO_FILL concentrates entirely on delivering pure puzzle-solving gameplay. Every stage feels like a self-contained challenge where understanding the relationship between tiles becomes the key to success. As players progress through increasingly complex boards, the game steadily introduces situations that require more careful observation and deeper analysis, creating a satisfying sense of mental engagement. The puzzle structure rewards experimentation without feeling unfair.…
