What you predict in the MLB game
Every league on TrueLine Daily asks for the same three kinds of number, but baseball asks them differently — the totals range is tighter than basketball or football, and the margin market is a fixed line instead of a moving one.
Projected total
5–15 runsThe combined runs the matchup was projected to produce. The slider moves in 0.5-run steps across the range real baseball totals actually close in, and landing within 0.5 of the number counts as nailed.
Home win chance
0–100%How likely the home team was to win, as a percentage. Baseball is the flattest of the major leagues here — a heavy favorite is often only a 60–65% call, so the gap between a good read and a bad one is narrower than it looks.
Run line
0–100%How likely the favorite was to win by more than 1.5 runs. Baseball uses a fixed 1.5-run line rather than a margin that moves game to game, so this is the same question every single day — which makes it the one you can genuinely get better at.
How a day plays out
Open the matchup
One real MLB game from earlier in the season, the same one for every player, with both teams' records as they stood that day. The result stays hidden. No research required — the point is your read, not your homework.
Make three predictions
Three guesses per number. After each one you're told whether the answer is higher or lower, so a miss still tells you something and you can close in.
Get scored against the close
When you finish, each number is scored 0–100 on how close you landed to where the market closed before the game. Your day's score is the average of the three.
Why you're scored against the closing number
A baseball game has one actual result, but that result is mostly noise — a bloop single decides plenty of games between two evenly matched teams. Scoring you on whether the game went over or under would be scoring you on luck.
The number the market settled on right before first pitch is the best public estimate of that matchup that exists. Scoring against it means a good read is rewarded even when the game itself did something silly, which is what makes the score worth chasing day over day.
It also means there is a real skill curve. Baseball's run totals move on things you can learn to feel — the park, the wind, who is starting, how deep the bullpen is — and the fixed 1.5-run line gives you the same question to get better at every day.

MLB prediction game FAQ
What is the daily MLB prediction game?
It is a free once-a-day baseball game. You get one real MLB matchup from earlier in the season, with the result hidden, and predict three numbers about it — the projected run total, the home team's chance to win, and the chance the favorite covers the run line. Every player gets the same matchup, and you get three guesses per number with a higher-or-lower hint after each.
Is this sports betting?
No. There is no wagering, no deposit, and nothing to win but bragging rights. You are predicting numbers about a game that has already been played, to test how well you read it. You cannot win or lose money.
What is the run line in the MLB game?
In baseball the margin market is a fixed 1.5 runs rather than a number that changes from game to game. So the question is always the same: how likely was the favorite to win by 2 or more? Because it never moves, this is the market where your reads compound fastest across a season.
How is my MLB score calculated?
Each of the three numbers is scored 0 to 100 on how close it lands to the closing number, and your day's score is the average of the three. Nailing a number on your first guess scores more than getting there on your third, so the hints cost you something.
How many runs should I guess?
The total slider runs from 5 to 15 runs in 0.5-run steps, which is the range MLB totals realistically close in. Most games sit in the middle of it; the park, the weather and the starting pitchers are what push a day toward either end.
Do I need an account to play?
No. You can play as a guest straight away. Creating an account saves your history and streak across devices, and your guest progress carries over when you sign in.
Can I play yesterday's MLB game?
Yes, if it's recent: today and the 2 days before it stay open to everyone. Daily Plus opens the full archive of past slates, lets you play every league on the same day instead of one, and includes a streak repair each week.
