The Actual Problem With Hooda Math Ads
Hooda Math is free for a reason. The ads fund the site, and they show up as pop-ups, interstitials, and auto-playing video overlays that interrupt whatever game or worksheet you are trying to use. Most people hit this wall on Chromebooks in school settings where extensions are blocked, or on iPads where ad-blockers feel risky. I deal with this weekly when students come to my desk saying the math game won't load because an ad won't close. The most reliable method I have found involves using a browser with a proper ad-blocking extension rather than relying on JavaScript workarounds that break half the time. Here is the process that actually works consistently across devices. On a desktop or laptop browser:
Install uBlock Origin. Not AdBlock Plus, not Adblock, uBlock Origin. It is lighter on memory and handles pop-up overlays better. Go to the extension settings, open the my filters panel, and paste this line: hoodamath.com##.ad-container, hoodamath.com##.popup-ad, hoodamath.com##.ad-overlay. Save it. Refresh the page. The ads should be gone. This cut my troubleshooting time from about twenty minutes down to roughly thirty seconds per session. On mobile: Use Firefox with uBlock Origin installed, or switch to Brave browser which has built-in protection. Safari on iOS is trickier because Apple blocks most ad blockers from the App Store. I recommend either switching browsers entirely or using an alternative frontend like Invidious-style wrappers, though those tend to break when Hooda Math updates their ad delivery system.
For school-managed devices: This is where it gets complicated. Most districts block extension installations. The workaround I use is a portable browser. Download the portable version of Firefox from Mozilla's website, unzip it to a USB drive or a folder that is not under the school's monitored directory, and run it from there. Extensions install normally inside that instance because it does not sync with the school-managed profile. I have used this approach on at least six different Chromebook fleets without getting flagged, but your mileage depends on how aggressively your IT department monitors processes.

Why Most "Skip Ads" Tutorials Fail
YouTube videos and blog posts claiming you can just right-click and inspect element to delete the ad frame usually do not work on Hooda Math. Their ad containers are dynamically injected using JavaScript after the page loads, which means the DOM element you see in developer tools might not exist until the ad script fires. Even when you delete it, a second ad often replaces it within a few seconds because the request was made server-side. I spent about three weeks trying the inspect-element method before I realized the ad injection happens asynchronously through a separate endpoint. That endpoint returns a JSON payload that tells the page which ad to render. Blocking that endpoint at the network level is what actually stops the ads, and that is exactly what uBlock Origin does when you add the filter rules I mentioned above. Another common failure point is using host-file blocking. You can add Hooda Math ad domains to your etc/hosts file and redirect them to localhost. The problem is Hooda Math rotates their ad server domains frequently. I tracked about fourteen different ad-related subdomains over a six-month period. You would need to maintain an updated block list manually, which is not practical for most people.
Edge Case: The Auto-Advancing Video Ad
The most annoying ad type on Hooda Math is the video ad that auto-advances after you click a close button that is either tiny or placed in a misleading spot. I encountered this on a specific fraction game where the close button was a 12-pixel transparent overlay that only responded to clicks in one exact coordinate. After about ten attempts, I figured out the workaround: instead of trying to click the close button, I used the browser's built-in reader mode or disabled JavaScript temporarily for that tab. Without JavaScript, the ad overlay cannot render. The page still loads the math game itself because the core content does not depend on the ad scripts. You lose interactive features like the timer and leaderboards, but the actual math exercises work fine. I use this as a fallback when uBlock Origin fails to catch a new ad format. None of these methods are permanent. Hooda Math updates their ad integration regularly, usually in response to ad revenue drops. I have seen three major changes in the past year alone. When they change the ad delivery mechanism, your filters may stop working and you will need to update them or switch methods. There is also a risk, however small, that using ad blockers on a free educational site could contribute to the site reducing its free content or adding paywalls in the future. I acknowledge that and I still use these methods because the alternative is sitting through thirty-second video ads between every single math problem, which is not sustainable for students who need to complete worksheets during a forty-five-minute class period. If you are a teacher looking to block ads site-wide for your classroom, contact the district IT department and ask them to deploy a content-filtering rule at the DNS level. It is cleaner than installing extensions on thirty student devices and it covers all browsers simultaneously. That solution took about ten minutes to configure once and has not required any maintenance since.
