Classroom reasoning
The game can support place value, elimination, and hypothesis testing without needing a custom worksheet.
Deduce the hidden 3-digit number using Strike and Ball hints.
Correct digit AND correct position
Correct digit but wrong position
No strikes or balls — none of your digits are in the answer
4 1 9→1S 0B3 2 1→1S 0B7 9 4→0S 2B4 2 7→3S 0B 🎉Number Baseball is a brain-teasing deduction game where you guess a hidden 3-digit number using pure logic and reasoning. After each guess, you receive hints in the form of Strikes (correct digit in the correct position) and Balls (correct digit in the wrong position), and an Out means none of your digits appear in the answer at all. Using these clues, you systematically eliminate impossible combinations and narrow down candidates to find the answer in the fewest attempts possible. The game tests your analytical thinking from the very first guess — experienced players know to start with digits spread across different ranges, such as 1, 5, and 9, to gather maximum information early on. As you accumulate Strike and Ball results across multiple tries, you can cross-reference clues to pinpoint exactly which digits belong in which positions. A result of 1 Strike and 1 Ball, for example, tells you two of your three digits are correct but only one is in the right spot, giving you powerful information to rearrange and retry. In solo mode, you challenge the computer's hidden number and aim to solve it in as few attempts as possible, with your best scores recorded on the global leaderboard where top players routinely crack the code in just three or four guesses. In multiplayer mode, you compete head-to-head against other players in real time to see who can deduce the answer first, adding a thrilling race element to the logical puzzle. The game supports both PC and mobile — simply type your three-digit guess and submit. Each round takes only a few minutes, making Number Baseball perfect for quick mental workouts during breaks. The combination of logical deduction, pattern recognition, and competitive pressure makes this one of the most addictive puzzle games available, rewarding players who develop systematic elimination strategies over those who rely on random guessing.
Q. How many digits is the number?
A. It's a 4-digit number with all unique digits.
Q. What's the minimum number of tries to solve it?
A. Theoretically 1, but on average it takes 5–7 attempts.
Q. Can the first digit be 0?
A. No, the first digit must be 1–9. The second and third digits can be 0.
Q. When does OUT occur?
A. OUT appears when none of your guessed digits are in the answer at all. OUT results are very useful since they let you completely eliminate those digits.

Use when
Players should reason out loud
The game can support place value, elimination, and hypothesis testing without needing a custom worksheet.
Because turns are based on guesses, players can talk through logic instead of focusing only on controls.
The winner is the player who interprets clues efficiently, which makes the game feel different from arcade score pages.
Number Baseball is slower and more mental. Use Bingo when the room needs a broader shared reaction, or use a roulette game when the room needs faster suspense.
The clue tracking can become frustrating if players cannot record eliminated digits and positions.
Use Number Baseball when students need a reasoning activity that still feels like a game.
Create a room for a slower match where players can think, discuss clues, and compare strategies.
Play solo and focus on reducing the number of guesses rather than simply finishing the round.
Number Baseball is deduction-heavy. Bingo is better when players want board planning and familiar shared rhythm.
Number Baseball is a full reasoning game. Wheel is better for choosing a student, prompt, or reward quickly.
Number Baseball asks players to solve a hidden answer. Ladder is for assigning visible names to visible outcomes.
