What Actually Happens in Hooda Math Split Ball
You drag a ball that has a number on it toward another ball. When they collide, they split into two new balls and the numbers combine based on the operation shown on the receiving ball. The goal is usually to produce a ball with a specific target number by chaining these collisions together. The game doesn't explain this well in any tutorial screen. You figure it out after about three failed attempts and one lucky match that works.
How to Play Hooda Math Split Ball
Each level gives you one or more starting balls and a target number at the bottom of the screen. Your job is to use addition, subtraction, multiplication, or division — whichever operation is displayed on the ball you're aiming for — to eventually create a ball that exactly matches the target. Once you get the target number, the level ends. Here's the part nobody tells you: order matters. Hitting ball A with ball B gives a different result than hitting ball B with ball C, especially when subtraction and division are involved. The operation always comes from the target ball that receives the collision, not the one you're dragging. So if you're dragging a 6 toward a subtraction ball, you're calculating 6 minus whatever number sits on the subtraction ball. I spent way too long on a level last month where I kept getting 4 when the target was 2, and the issue was that I was dragging the wrong ball in the wrong direction. The game registers the collision based on which ball has the operation symbol, and I was completely backwards about it. Workaround was simple but unintuitive: always drag the numbered ball INTO the operation ball, never the other way around. It sounds like it should work both ways, but it doesn't.
Multiplication and division levels are where most people stall. They're not harder mathematically, but the branching factor explodes quickly. A single wrong split can eliminate every path to the solution, and there's no undo button in most versions.

Where to Find It
Hooda Math is a free browser-based platform. You don't download anything. You go to hoodamath.com and search for Split Ball. It runs in Chrome, Firefox, Safari, Edge — all of them. No account required. The game sometimes gets re-skinned or rearranged on the site as they update their library, so if it's not on the front page, type "Split Ball" into the search bar directly. That said, the game occasionally breaks in certain browser configurations. I had a level where the drag-and-drop stopped registering on a tablet version of Safari while it worked fine on desktop Chrome. Switching to portrait mode and using a mouse instead of touch input fixed it. I never figured out why.
Things That Make This Game Annoying
First, some levels are poorly designed. I hit a division level where the only solution required creating a fraction as an intermediate step, but the game doesn't display fractional balls — it just silently rejects them. You have to work backward from the target number and figure out the path without any feedback when you fail. That level took me roughly eight minutes because the intended solution involved splitting a 12 into a 3 and a 4 through multiplication first, then dividing through the right sequence. Second, there's no save state between levels. If you close the tab, you start over. This seems minor until you're on a school network and the tab gets auto-cleared by some filtering software. Third, the difficulty curve is jagged. You'll breeze through twelve addition and subtraction levels, then hit a multiplication block that requires actual mental arithmetic beyond what you do daily, then suddenly it drops back down to easy division problems. There's no pattern to the sequence that helps you prepare.
For people who find the math side frustrating, the alternative is to treat it like a visual logic puzzle rather than a math exercise. Focus on the collision mechanics first and do the arithmetic second. It removes some of the pressure and lets you see the structure of the problem more clearly.
