Zero Numbers
A clever number-merging game that tests your basic arithmetic skills. Slide tiles to merge them; same values disappear while different values sum up. The goal is to clear the board entirely by reaching zero.
About This Game
Zero Numbers is a Subtractive Arithmetic puzzle that focuses on Numerical Elimination and Sequential Logic. This title emphasizes "Non-Zero Sum" gameplay, where the player must merge tiles with identical values to reduce them to zero. It is a game of "Spatial Calculation," requiring players to plan the order of mergers to ensure that no "Lone Integers" are left without a partner on the board.
How to Play
Drag a numbered tile onto an adjacent tile of the same value. The gameplay is Cancellation Logic: when two identical numbers collide (e.g., 5 and 5), they both vanish. The interaction involves "Grid Management"—as you remove tiles, the remaining numbers stay in place. You must clear the entire board to pass the level. You cannot merge tiles with different values.
Tips & Tricks
High scores are earned through Chain-Clearing Streaks. Removing multiple sets of numbers in rapid succession provides a "Mathematical Flow" multiplier. The pro secret is "Centripetal Planning"—work from the edges toward the center to avoid isolating a number in a corner where it cannot be reached by its matching pair. Completing a level with "Zero Mistakes" grants a "Perfect Logic" medal.
Frequently Asked Questions
Q: What if I have three 5s?
A: You will be left with one 5 after merging the first pair, causing a level fail. You must always ensure an "Even-Numbered Distribution" of every digit.
Q: Is there a time limit?
A: No, the game is a "Zen Logic" puzzle, allowing you as much time as needed to calculate the total parity of the board.
