Zero Logic

Turn the Monster’s Number Into Zero

Zero Logic is a math puzzle game where numbers become your weapons. A monster appears with a number, and your job is to reduce that number to exactly zero. Instead of typing an answer into a box, you use six different math guns. Each gun contains a number together with an operation such as addition, subtraction, multiplication, or division.

The idea is easy to understand, but finding the correct order can require careful thinking.

Understand What Each Gun Does

Imagine that the monster currently shows 20. A gun marked “-5” changes that number to 15 when fired.

A gun marked “×2” would double the current number instead. Division and addition work in the same way.

This means the order of your shots matters. Multiplying first and subtracting afterward can produce a completely different result from using those guns in the opposite order.

Every Gun Can Be Used Only Once

You cannot keep firing the same useful weapon until you reach zero. Each of the six guns can be used only once during a level.

This forces you to plan the full calculation.

It helps to look at all six options before using the first one. Think about which operation brings the monster closer to a number that another gun can handle.

Using fewer guns also gives you a higher score.

Choose Between Two Ways to Play

Zero Logic includes an Unlimited mode and a challenge made up of 50 levels.

The challenge mode gives you a clear set of puzzles to complete. Unlimited play is useful when you want to continue solving number problems without stopping after a fixed stage.

Zero Logic turns basic arithmetic into a small strategy puzzle. Study the monster’s starting value, inspect the available math guns, decide which operations should come first, and try to reach exactly zero with as few shots as possible.
