Welcome to the Zero Puzzle game! In this number puzzle game, you need to move and combine number blocks to make all the numbers become zero. Challenge your mathematical wit and solve these 50 mathematical puzzles!

Game rules:

Objective: Turn all the numbers into zero by moving number blocks.
Movement: In each step, you can move a number block horizontally or vertically to an adjacent empty space.
Merging: When two number blocks are adjacent and their values add up to zero, they will merge into one block. For example, (+2) and (-2) will merge into an empty space.
Number Range: The initial number range is usually between positive and negative numbers, but the values stay the same. For instance, when (+2) is adjacent to (-1), the next step will turn (+2) into (+1).
Block Elimination: Each step reduces the number of blocks on the board by 1. Be careful not to reduce the number of blocks to zero, or the block will disappear from the game board.

The game features 50 carefully designed mathematical challenges waiting for you to solve. Each level is more challenging than the previous one, requiring more mathematical skills and strategies. Enjoy the game and have fun!
