What is Nullify Game?
Nullify corner is an online browser game where you clear the screen by merging circles. Some circles are numbers, and some circles act like math tools you can use to change a number. When a merge creates 0, the circle disappears. Clear every circle to win the level.

Nulify is known for its simple black-and-white look, short levels, and satisfying "make it vanish" goal. Many players like it because it feels like a logic challenge, not a worksheet.
Release info you may see on public game listings: the web browser version is listed as October 2022, with mobile listings showing August 2022 for Android and August 2023 for iOS.
Try this before your first move: pick one circle you want to remove, then decide what opposite number would cancel it to 0. That tiny plan makes the whole puzzle feel easier.
Nullify Gameplay
In Nulify, you move circles together to merge them. Each merge uses two circles and leaves you with one new circle. Because the board gets smaller every time you merge, the order of your moves matters.
Most puzzles in the Nullify game are about building a number and then canceling it with the opposite number. For example, if you can create +12, then you can erase it by merging it with -12 to make 0.
Some circles help you adjust a value in small steps (like adding or subtracting). Other circles can change values quickly (like multiplying or dividing). A good solution usually mixes both: shape a number first, then finish with a perfect cancel to 0.
- Merge two circles to create a new value.
- If the new value is 0, the circle disappears.
- Clear every circle to complete the level.
Example play: you have -6, x2, and +12. Merge -6 with x2 to get -12. Then merge -12 with +12 to make 0, and the circle vanishes.
When the board looks messy, a helpful trick is to solve backwards. If you see a +14 that you want to erase later, you already know you will need a -14 at the end. Now the puzzle becomes: how can you create -14 using what you have left?
Nullify corner is not about fast reflexes. It is about calm choices. Take a second, look for an easy 0, and build from there.
Nullify Levels, Modes, Characters, or Upgrades
Nullify corner focuses on puzzles, not characters or power-ups. Instead of upgrades, you get smarter by learning patterns and improving your move order.

How to Play Nullify Game
The goal in Nulify is simple: make every circle become 0 so it disappears. The challenge is choosing the best merge order so you never get stuck.
- Goal: remove every circle by turning circles into 0 through smart merges.
- First, scan the board and look for an instant 0 move (like -5 and +5).
- Next, choose one "problem number" and decide what opposite number you will need to cancel it.
- Use math-symbol circles to shape numbers into your target values.
- Try to plan your next two moves, not only the next one.
- Keep at least one clear path to 0 for the circles you leave behind.
- Finish by canceling the last circles into 0 until the screen is empty.
Beginner idea: think of your circles as tools and targets. Tools help you change values. Targets are the numbers you plan to cancel. Good play means you use tools carefully and save the best cancel pairs for the right moment.
A common mistake is making a big number just because it looks interesting. Big numbers are not bad, but they can be harder to cancel if you do not also have the opposite value available.
Another common mistake is using your only strong tool too early. If you have one helpful multiplier or divider, ask yourself which number needs it most before you spend it.
Nullify Game Controls
Desktop: click and drag circles with the left mouse button to merge them.
Mobile and tablet: touch and drag circles to merge them.
Controls may vary slightly by device, but the core idea stays the same: drag one circle onto another to merge.
Nullify Tips and Tricks
These tips are made for kids and beginners, but they also help experienced players solve harder levels in the Nullify game.
- Look for "free zeros" first: if two circles cancel right away, clear them to open space.
- Think in opposites: if you create +10, you will need -10 later. Always ask, "Where will the opposite come from?"
- Solve backwards when stuck: pick the circle you want to erase last, then plan how to build its opposite.
- Use small changes before big changes: add or subtract to tidy a number, then multiply only when you know your target.
- Protect rare numbers: if you only see one +7, do not spend it on a random merge.
- Try to make tidy numbers: values like -12, +12, -10, +10 are often easier to cancel than strange numbers.
- Keep a safety move: division can sometimes rescue a number that grew too big, but only if it creates a clean result.
- Do not waste merges: if a move creates a messy value with no clear plan, stop and rethink.
- Clear crowded clusters early: fewer circles in one area makes it easier to spot the best merge order.
- Plan two moves ahead: after your move, check if the new circle still has a path to 0.
- Make cancel pairs on purpose: if you can keep +8 and -8 available, you have an easy finish later.
- Replay levels to improve: solving the same level again helps you learn patterns fast.
Quick pattern guide for the Nullify math puzzle:
- Cancel pair: keep a number and its opposite, then merge them when you need space.
- Build then cancel: use one tool to shape a number, then erase it with the opposite value.
- Step ladder: change a number in steps, like -9 to -6 to -12, then cancel with +12.
- Clean-up move: when the board is messy, erase one easy 0 first to reset your thinking.
Example play: you see -8, x2, and +16. Merge -8 with x2 to get -16, then merge -16 with +16 to make 0. That is a classic "build then cancel" win.
Kid-friendly reminder: if you feel stuck, do not panic. Pick one circle, decide what opposite number you need, and work toward it step by step.
