on diamondtrivia.app
Diamond Trivia is a daily MLB trivia app and website. Each day brings a new lineup of baseball games: name the players who led a stat category, work out the teams behind a finished grid, pick which player had more, or draft a five-player roster and see how close it comes to a perfect 162-0 season. Results go on leaderboards, and some games can be played head to head.
About Diamond Trivia
The daily lineup is built on MLB statistics. In Strikeout you get a prompt such as the qualified players with the highest batting average in a season, and fill the board by naming them, with three strikes for misses. Reverse Immaculate turns the familiar team grid around: you see the players and must name the six team headers that fit each row and column. Higher Lower asks which of two players recorded more of a stat, Stat Stack drafts player-seasons that meet changing constraints to build the highest-scoring five-player stack, and 162-0 spins a franchise and era, lets you draft five players and projects your club's record. The app also lists Guess the MLB Season, where you name the year from its stat leaders.
Today's lineup can be played on the website at desktop or phone size, while the app adds performance stats, collections, achievements, sharing and leaderboards. Strikeout, Higher Lower and 162-0 also have real-time online play against other fans on an Elo ladder, or in private lobbies of up to 15 friends.
The daily games are free and the website plays with no account and no ads. An optional Diamond Pro upgrade in the app adds more tickets, saved progress, rewards, daily leaderboards and unlimited play. The app came out on iOS in March 2026 and is also on Google Play; the September 2026 update added online multiplayer.
How to play Diamond Trivia
- Open diamondtrivia.app or the app and pick a game from today's lineup.
- Read the prompt carefully: check whether it asks for a career total, a single season or a particular team.
- In Strikeout, type players who match the prompt to reveal tiles; each miss is a strike, and three strikes end the game.
- In Reverse Immaculate, choose the team shared by every player in a row or column.
- Finish the lineup and compare your results on the leaderboards.

Tips
- Start with the players you are most sure of, then work through the rest by era or position.
- A player who meets the stat can still be wrong if the team or years do not match the prompt.
- In Reverse Immaculate, check a team against every player in the line before spending a guess.
