Acceptance of these terms
These terms are an agreement between you and Origin Labs, the developer of Stick Math, referred to here as "we" or "us", covering your use of the Stick Math app and this website. By downloading, installing, or playing Stick Math, you agree to these terms. If you don't agree, please don't use the app.
The service
Stick Math is a puzzle game where you move a matchstick to turn a wrong equation into a correct one. Features, including multiplayer, points, streaks, and favorites, can change as the game is updated, and we'll update this page when a change affects these terms.
Eligibility
Stick Math is intended for people 13 and over. If you're under the age required by your country to agree to terms like these on your own, a parent or guardian needs to agree on your behalf. We do not knowingly collect personal information from children under 13; if you believe a child has provided us with personal information, contact us through the contact form and we'll remove it.
Accounts
You can play as a guest with no account, or sign in with Google, Sign in with Apple, or an email address and password. Signing in enables cloud sync, so your progress carries over between devices, and enables multiplayer.
You're responsible for keeping your sign-in credentials secure and for anything that happens through your account. Tell us if you believe your account has been accessed without your permission. See our Privacy Policy for how account and sync data are handled, and for how to request deletion of your account.
Points, hints, and progress
Points, streaks, favorites, and level progress are in-app systems with no monetary value. They can't be exchanged for cash, transferred to another player, or redeemed outside the app. We can adjust balances, reset progress, or change how points are earned or spent, including to correct an error or address abuse.
A puzzle offers two kinds of help. A hint shows you where to look. Show reveals the answer and solves the puzzle for you. Both are bought with points you earn by solving. If you don't have enough points, the app may offer an optional short video instead, one for a hint and two for Show. New players also get a few free hints and Shows. Using Show earns no stars or completion points and doesn't count toward your daily streak. Prices, and how each kind of help is unlocked, can change as the game is balanced.
The app previously offered a second, stronger hint that showed the exact matchstick to move and where to put it. That second hint was removed on September 2, 2026, so there is now a single hint per puzzle. Any points you had already spent on it are unaffected.
Stick Math is free and doesn't require any purchase to play. Ads keep it free. The iPhone and Android app shows ads from Google AdMob: banners on the multiplayer screens, an occasional full screen ad between puzzles, and optional videos you choose to watch for a hint, a Show, or a missed streak day. New players don't see full screen ads at first. In some regions you're asked for your ad choices before any ads are requested. Versions of Stick Math on other game websites show that website's ads. Our Privacy Policy explains what the ad provider collects. If optional paid features are introduced later, their own terms will be presented at the time and this page will be updated.
Multiplayer conduct
Multiplayer rooms are shared spaces with other players you've invited or been invited by. When you join a room, your player name and your results in that room's rounds are visible to its other members, as described in our Privacy Policy.
Don't cheat, try to manipulate round timing, or exploit the game to gain an unfair advantage. We can remove a player from a room, or suspend an account, for behavior that violates this.
Player names and room names
Your player name and any room name you choose are seen by other players. They must not be:
- Offensive, hateful, or harassing, including slurs and threats.
- Sexual or otherwise unsuitable for a general audience.
- Pretending to be another person, a brand, or Stick Math.
- Personal information, such as a phone number, address, or email address.
- Infringing someone else's rights.
In a room you can Report a player or the room, and Block a player so their name no longer shows to you. We review reports, and we can change or remove a name, delete a room, remove a player from a room, or suspend access to multiplayer or to the app.
Acceptable use
- Don't reverse engineer, decompile, or tamper with the app beyond what's allowed by law.
- Don't attempt to access another player's account or another room's data.
- Don't use the app to send unsolicited messages or to abuse or harass other players.
- Don't interfere with the app's servers or the fairness of multiplayer rounds.
Ownership
Stick Math, its puzzles, artwork, logo, and design are owned by us or our licensors and are protected by intellectual property law. Playing the app doesn't transfer any ownership to you. We grant you a personal, non-exclusive, non-transferable license to use the app for its intended purpose, on a device you own or control, for as long as these terms remain in effect.
Disclaimers
Stick Math is provided "as is" and "as available". We don't guarantee the app will be uninterrupted, error-free, or available at all times, and we don't make any claim about mental, cognitive, or health benefits from playing it. To the extent allowed by law, we disclaim warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.
Limitation of liability
To the extent allowed by law, we won't be liable for indirect, incidental, special, or consequential damages arising from your use of the app, even if we've been advised of the possibility. Nothing in these terms limits liability that can't be limited under applicable law.
Termination
You can stop using the app at any time, and can request deletion of your account as described in our Privacy Policy. We can suspend or terminate access to the app, including a specific account or multiplayer room, for a violation of these terms or for behavior that harms other players or the service.
Governing law
These terms are governed by the laws of the State of Arizona, United States, without regard to its conflict of laws principles. Any dispute arising from these terms or your use of the app will be resolved in the courts of that jurisdiction, except where local law gives you the right to bring a claim elsewhere.
Changes to these terms
We can update these terms as the app changes, including if paid features are introduced. We'll update the effective date above when we do. Continuing to use the app after an update means you accept the revised terms.
