OddsOff Blocker

Blocks gambling sites and turns every blocked page into a moment of support: breathing exercise, your streak, and real help.

OddsOff Blocker helps people quitting gambling stay quit. It blocks online casinos, sportsbooks, sweepstakes, and crypto gambling sites right in your browser. But unlike other blockers, hitting a wall here doesn't leave you at a dead end at the exact moment an urge peaks. Instead, the blocked page offers: • A guided one-minute breathing exercise to ride out the urge • Your gambling-free streak and the money still in your pocket • One tap into the OddsOff community's 24/7 Urge Support room • The 1-800-GAMBLER helpline — free and confidential Works instantly after install with a built-in blocklist; syncs the latest list automatically. Optionally pair it with a free OddsOff account (oddsoff-app.web.app) to see your streak and money saved on the blocked page and count this device toward your protection coverage. We never see your browsing. Blocking happens on your device through Chrome's declarativeNetRequest API — the extension cannot read the pages you visit, and no history or URLs are ever transmitted.
