Bring everything to zero in ZERO_FILL. At the heart of the game is a simple, tactile mechanic: tap a square to adjust its value, and that action also nudges its neighboring cells. The grid becomes a web of cause and effect, where a single move can ripple across the board in unexpected ways. Your goal is to reduce every cell to zero, but each step must be chosen with care, because limited moves stand between you and victory.

Core mechanics

• Tap a square to increase or decrease its value. The change affects the square itself and its immediate neighbors, creating potential chain reactions.
• Every board in the Campaign has a fixed number of moves. Plan each move to maximize impact while staying within the limit.
• Undo and Reset are your allies. Rewind missteps, replay layouts, and refine your approach without starting from scratch.

From approachable puzzles to intricate grids, progress through layouts designed to test timing, foresight, and pattern recognition.
