Why people come back.

CogniBump is a small, independent studio in Colorado. Every game is hand-built and every question is hand-written.

Five tips that actually help.

Small habits that consistently move the score, from watching a lot of people play.

  1. Open with vowel-heavy words.

    In WordRush your first guess gathers information. STARE, RAISE or AROSE cover four of the five most common letters in English.

  2. Read all four options before you click.

    The Daily 5 timer rewards speed, but a misclick costs more than a slow right answer. A two-second scan avoids the trap option sitting next to the real one.

  3. Learn flag families, not flags.

    Nordic flags share a sideways cross; Pan-African flags share red, gold and green; Pan-Arab flags share black, white, red and green. Patterns get you 30+ flags fast.

  4. In a relay, pass the easy guesses.

    TagTeam rewards the team. Save your highest-confidence guess so your partner gets the wide-open finish — it feels generous and plays smarter.

  5. Anchor a streak to a habit you already have.

    Streaks die when they're "later." They survive when they're tied to coffee, lunch, the train or bedtime. Pick one anchor and it sticks within two weeks.

Is CogniBump really free?
Yes — free forever. The site is supported by ads (we use Google AdSense) and there's no premium tier or paywall. Every game on this page is the full game; nothing is held back behind a signup. See the privacy policy for how ads and analytics work.
Do I need to create an account?
No. There is no signup flow on CogniBump. Your scores, streaks and saved games live in your browser's local storage. Clearing your browser data (or playing in a private window) wipes your progress — but it also means we don't keep a profile of you on a server.
How do daily streaks work?
Each daily game tracks how many days in a row you've played. Streaks reset if you skip a day or clear browser data. Because the streak lives in your browser, playing on your phone and your laptop builds two separate streaks. More on how this works.
Is CogniBump safe for kids?
The games are general-audience and never ask for personal information. There are no profiles, no chat and no social features. Ads are served by Google AdSense; if your school or family restricts third-party ads, check your IT policy before projecting the site in class. Our parents & teachers page has more guidance.
How do I challenge a friend?
Open any game in Play a friend — Pass the Putt, WordRush Challenge or a TagTeam game — play your turn, and copy the link from the share button. Your friend opens it in their browser and the game is waiting. No account on either side; nothing to install.
Why is the same puzzle live worldwide?
Because comparing is half the fun. If you played a different puzzle than your sister or your coworker, the score wouldn't mean anything. A shared daily puzzle means you can actually argue about whose answer was smarter.
Can teachers use CogniBump in class?
Yes. The math drills, geography quizzes and Daily 5 work well as five-minute warmups, and there's no student login or roster setup. Project the site or share a URL — that's it. The teacher guide has pacing suggestions and a note on ads.
Who makes CogniBump?
CogniBump is published by TradeHawk HQ LLC, an independent studio based in Colorado, USA. Every game is hand-built and curated — no syndicated question feeds. Spot an error in a question? Email hello@cognibump.com and the person who built the game will read it.
