Yes. The game uses JavaScript's built-in Math.random() function, which generates pseudorandom numbers using your browser's random number generator. While no software-based RNG is "truly" random in a cryptographic sense, the algorithm produces results that are statistically indistinguishable from fair dice rolls for gaming purposes. Every roll is independent, meaning previous results have absolutely no effect on future outcomes.
Your chance of winning a single game (surviving 10 rolls without a 1) is exactly 16.15%, or roughly 1 in 6.2 attempts. This comes from the formula (5/6)^10. Each roll has a 5 out of 6 chance of being safe, and multiplying that probability across ten independent rolls gives you the overall win rate. For a deeper dive into the math, visit our Probability Guide.
The game is not rigged. With an 83.85% chance of losing each round, most attempts end in failure. Losing several games in a row is not only possible but expected. The probability of losing 10 games in a row is about 16.8%, meaning roughly one in six players who play exactly 10 games will not win any of them. If you feel the game is unfairly difficult, it is actually a demonstration of how poorly human intuition handles compound probability. We expect each roll to be easy (83.3% success), so we underestimate how quickly those probabilities stack against us.
The leaderboard tracks the highest win streaks among players who sign in with Google. It has two tabs: Daily (top 10 scores for today) and All-Time (top 25 scores ever). Scores are ranked primarily by win streak length, with total attempts as a tiebreaker (fewer attempts is better). Your score is only updated when you achieve a new personal best, so playing more games never lowers your ranking. You can save your score after any win using the "Save to Leaderboard" button.
No. The game is fully playable without signing in. All game statistics (wins, streaks, attempts) are stored locally in your browser and do not require an account. Signing in with Google is only needed if you want to save scores to the leaderboard and compare your performance with other players.
Yes. Never Roll a 1 is fully responsive and works on smartphones and tablets of all sizes. The interface adapts to smaller screens, and all features including rolling, stats tracking, sharing, and the leaderboard work on mobile browsers. For the best experience, use a modern browser like Chrome, Safari, Firefox, or Edge.
Yes. Game statistics (scores, streaks, attempt counts) are stored locally in your browser's localStorage, meaning they never leave your device unless you choose to save a score to the leaderboard. If you sign in for the leaderboard, we store only your display name, user ID, win streak, and attempt count in our database. We do not access or store your email, Google profile data, or any other personal information. For full details, see our Privacy Policy.
Daily stats (today's wins, today's attempts, current win streak) reset automatically at midnight local time. This is by design so that the daily leaderboard tracks fresh competition each day. All-time stats (total wins, total attempts, all-time best streak) are preserved across days. If all your stats disappeared, you may have cleared your browser's local storage, used a private/incognito window, or switched to a different browser or device. Since data is stored locally, it does not sync between devices.
The core game requires an initial page load from the internet, but once loaded, the dice rolling and stats tracking work without an active connection since all game logic runs in your browser. However, leaderboard features, ads, and saving scores to the server require an internet connection. If you lose connectivity mid-session, your local stats will still be saved.
