EloGuess
Got a question about EloGuess? Here are the most common answers about how the game works, what each mode means, how to improve your Elo guesses and where to report issues.
EloGuess is a chess rating guessing game. You watch real chess games, follow the moves, look at the clocks and time control and try to guess the player’s Elo.
The challenge is about reading the level of play behind the moves!
Each round shows a real chess game. Watch how the player handles the game, then make your rating guess.
Depending on the mode, you may choose a rating range or enter an exact Elo number.
Good Elo guesses usually come from combining several clues. One move rarely tells the full story, so try to judge the overall pattern of play.
Useful clues include:
A strong guess comes from reading both the board and the player’s decision-making.
Yes. EloGuess uses real Lichess chess games and game data. Every round is based on decisions made by an actual player, so it's not a made-up puzzle.
Hard Mode gives you a ten-move excerpt instead of the full game. It removes the opening context and evaluation bar, so you have less information to work with.
Easy and Medium show the full game. Easy also includes an evaluation bar.
EloGuess has five ways to play:
Daily, Classic, Exact and Streak are meant to be played solo. Duel lets you face a friend privately or play ranked against an online opponent.
Easy shows the full game with an evaluation bar. Medium shows the full game without the evaluation bar. Hard gives you a ten-move excerpt without the engine help.
Medium and Hard unlock after you reach the required score in the previous difficulty.
The Daily Challenge gives everyone the same five games for the day. You get one attempt and make five exact Elo guesses.
Once you finish, you wait for the next day’s challenge.
Duel puts two players in the same games. Both submit an exact Elo guess and the less accurate player loses HP.
Private rooms are unranked. Online matchmaking uses a personal Duel rating.
The Daily Challenge is designed as a once-per-day run so leaderboard scores stay fair.
You can still play Classic Mode, Exact Mode, and Streak Mode whenever you want!
Classic Mode uses rating ranges instead of exact numbers. Watch the game and choose the range that best matches the player’s level.
It is less about hitting one perfect number and more about recognizing the general strength of the player.
Exact Mode is for precision. Instead of choosing a rating range, you guess the exact Elo number.
You do not need to be perfect to improve. The goal is to get closer over time by learning rating patterns.
Streak Mode gives you three lives. Keep making good guesses to stay alive and build the longest run you can.
If your guesses are too far off, you lose lives. And when your lives are gone... the streak ends.
Time usage is important rating context! A move played instantly, a long think in a critical position or a mistake in time pressure can all reveal something about a player’s level.
A blitz game and a longer game can also feel very different, so the time control helps you judge the game more fairly.
Leaderboards let you compare your results with other players. Scores are separated by mode and difficulty so runs stay fair and easy to compare.
Your leaderboard name and avatar can be changed in Settings.
No. You can play EloGuess without creating an account or connecting a chess account.
Your local settings and progress are stored in your browser, while leaderboard entries use the display name and avatar you choose.
Your Statistics page tracks your progress across different modes. You can use it to see your best scores, total games, daily progress, and how your rating intuition improves over time.
Achievements are goals you complete while playing EloGuess. They give you extra things to aim for beyond a single score.
Some achievements unlock new avatar rewards that you can use on the leaderboard.
Your progress may be stored locally in your browser. It can disappear if you clear browser data, use a different browser, switch devices or play in private/incognito mode.
You can remove local EloGuess progress by clearing this site’s browser storage in your browser settings.
Keep in mind that this may remove local statistics, settings, achievements, saved display preferences and Daily Challenge status from that browser.
EloGuess is not a tactics trainer, opening course or engine analysis tool. It trains a different skill: recognizing the strength of play.
Over time, you may get better at spotting rating clues such as time trouble, tactical sharpness, opening comfort, conversion technique and common mistakes.
Yes. Beginners can start with Classic Mode because rating ranges are easier than exact Elo guesses.
You do not need to know every opening or tactic. The game is about learning to recognize patterns in how different rating levels play.
