Sum Zero is a mobile puzzle game where the player has to bring all the tiles on a grid down to zero using math-based sliders. The game involves strategy, logic, and basic arithmetic to solve each level.
In Sum Zero, players are presented with a grid of tiles that can vary in size from 2x2 up to 5x5 cells and each shape in between those sizes. Each tile contains a number between -4 and 4. The player's goal is to manipulate these numbers using sliders to make every tile on the grid equal to zero.
- Grid Size: Levels range from a 2x2 grid to a 5x5 grid, providing increasing difficulty as the grid size grows.
- Tile Values: Each tile can have an initial value between -4 and 4.
- Sliders: Sliders are positioned on the sides of the grid and apply operations to a row or column of tiles. The available slider operations include:
- Add 1: Increases the value of each tile in the selected row or column by 1.
- Remove 1: Decreases the value of each tile in the selected row or column by 1.
- Invert Sign: Multiplies the value of each tile in the selected row or column by -1 (positive becomes negative and vice versa).
- Block Tile: Sets each tile in a row or colum to 0 and prevents any further slider from affecting it.
- At the start of each level, the grid is populated with tiles containing values between -4 and 4.
- Use the sliders on the grid's sides to manipulate the rows and columns.
- Try to find the optimal combination of slider movements to bring every tile's value to 0.
- Some tiles may be blocked, some may be missing.
- Once all tiles are set to zero, the level is complete!
- With increasing grid sizes, finding the right sequence of slider movements becomes more complex.
- The puzzle requires logical thinking, as certain moves may seem beneficial at first but complicate the puzzle in later steps.
- Varying grid sizes (from 2x2 to 5x5) for different difficulty levels.
- A range of mathematical sliders to manipulate the tiles.
- Strategic decision-making: Blocking tiles and deciding the best sequence of operations is key to solving the puzzle efficiently.
- Minimalistic yet challenging gameplay with endless possibilities for level design.
