Number Sweeper 3D is a challenging three-dimensional logic-puzzle game that's slightly similar to classic Minesweeper. It displays colored hexagons, also known as hex cells, in various patterns against a white background. The black hexagons feature white numbers. The non-numbered cells display a solid gray color. The player's goal is to reduce the numbers until all numbered cells feature green zeroes.
With Minesweeper, the goal is to select non-mined squares based on numbers displayed in open non-mined fields and spaces that show the number of nearby mines adjacent to a number. With Number Sweeper 3D, the goal is to flip blank gray hexagons without reducing any number down to a negative number.
For example, the game might display two black numbered hex cells with two blank shared gray cells between them. If the first cell displays a 2, the other cell displays a 1, and the player flips a cell between them, they can't flip the second shared cell to reduce the 2 to 0. Instead, they must flip a cell on the other side of the 2 cell. If they flip the second shared cell, the cell that dropped from 1 to 0 becomes a red -1.
Unlike Minesweeper, Number Sweeper 3D doesn't penalize the player if they accidentally make a numbered hex cell temporarily negative. When the player wins, Number Sweeper 3D flips all hexagons to display a one- or two-colored pattern, confetti bursts across the screen, and a shining golden treasure chest appears. The game also makes a pleasant and relaxing popping sound both during individual cell flips and after each win.
