Diamond Trivia

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, 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, with an optional Diamond Pro upgrade. The app came out on iOS in March 2026.

How to play Diamond Trivia

1. Open the app or diamondtrivia.app and pick a game from today's lineup.
2. Read the prompt carefully: check whether it asks for a career total, a single season or a particular team.
3. In Strikeout, type players who match the prompt to reveal tiles; each miss is a strike, and three strikes end the game.
4. In Reverse Immaculate, choose the team shared by every player in a row or column.
5. 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.
