How to play Baseball Ninja
- Choose a mode: the Season, the Ninja Cup, a Quick game, the Daily game or the Home Run Derby.
- When you bat, drag to place the bat circle and tap SWING as the ball reaches you.
- When you pitch, choose a pitch, aim in the strike zone and press PITCH when the ring is small.
- Score more runs than the other team before the last out of the last inning.
- Win coins, collect and upgrade players in your team and climb the leaderboards.
On a computer use the mouse (move to aim, click to swing or pitch), or ← → ↑ ↓ to aim and Space to swing or pitch, 1 to 5 to choose a pitch and Esc to pause. On a phone drag one thumb on the field and press the big round button with the other.
Batting: timing, aim and power
You bat from behind home plate. The strike zone is the box in front of you. Place the bat circle where the ball will cross the box and swing so that the bat reaches the ball at the same moment. A perfect swing puts the ball in the middle of the circle at the right time.
| What you do | What happens |
|---|---|
| 🎯 Circle under the ball | The ball goes up: fly balls and home runs. Circle above the ball gives ground balls. |
| ⏱️ Swing early | The ball is pulled and can go foul. |
| ⏱️ Swing late | The ball goes the other way, and a very late swing misses. |
| 💥 Perfect contact | The longest hits: over 105 metres is a home run. |
| 🧢 Batter ratings | Power adds distance and contact makes the timing window and the circle larger. |
Pitching: five pitches and the ring
When you pitch you stand on the mound. Choose one of five pitches, move the target and press PITCH while the outer accuracy ring is small. After the throw the ball is a strike if it ends in the zone box and a ball if it ends outside, and the computer batter swings more often at pitches in the zone. Your last pitches stay on the screen as coloured dots, so you can see where you have been throwing.
| Pitch | Speed | Movement |
|---|---|---|
| 🔥 Fastball (4FB) | Fastest | Straight, a little rise |
| 🟣 Sinker (2FB) | Fast | Drops and runs in |
| 🔵 Curveball (CB) | Slow | Big drop late in the flight |
| 🟡 Slider (SL) | Medium | Breaks sideways |
| 🟢 Change-up (CH) | Slowest | Looks like a fastball, arrives late and low |
A pitcher gets tired: after about 36 pitches the ring gets wider and the throws less accurate, so strike batters out early.
Team building
You start with 11 players. Every game earns coins: a win pays more, and the Season and the Ninja Cup pay extra. Spend coins on Scout packs (a random new player, Common, Rare, Epic or Legend) and on upgrades: each level adds 4 to every rating, up to level 5. Set the batting order by selecting a player and tapping the one he should swap with, and choose your starting pitcher. Batters have Power, Contact, Speed and Eye; pitchers have Velocity, Control and Break.
Season, Ninja Cup, Quick game, Daily game and Home Run Derby

Baseball Ninja tips
- Watch the ball, not the pitcher. Start the swing about a tenth of a second before the ball reaches the zone: the bat needs time to come around.
- Place the circle early. Decide where the ball will cross the box while it is still far away, then only worry about timing.
- Take pitches outside the box. A ball is a ball. Four of them are a free walk to first base.
- Use the corners when pitching. Pitches in the middle are hit hard. Aim at the edges, and below the zone with two strikes.
- Change speeds. After two fastballs, a slow curveball or change-up is much harder to hit.
- Upgrade your leadoff and your pitcher first. They play in every inning and every game.
Frequently asked questions
Is Baseball Ninja free?
Yes. Baseball Ninja is completely free to play online, with no sign-up, no download and no in-app purchases. It runs in your browser on computers, tablets and phones, and the single-player game keeps working without a connection once the page has loaded. The coins in the game are earned by playing, never bought. Your team, stars, stats and badges are saved on your device.
Is Baseball Ninja like Baseball 9?
Yes, Baseball Ninja is a Baseball 9-style game: a cartoon baseball game with big-headed players, a view from behind the pitcher, pitch types, collectable players and tournaments. It has its own players, stadiums, art, music and rules. Baseball 9 is a trademark of its owner; Baseball Ninja is an independent game and is not affiliated with or endorsed by it.
How do I bat?
When your team is at bat you see the field from behind home plate and the pitcher throws toward the strike zone box. Drag on the screen (or move the mouse) to place the bat circle where the ball will cross the box, then tap SWING (or click, or press Space) so that the bat meets the ball just as it reaches you. A swing that is too early pulls the ball and may go foul, a late swing goes the other way, and a swing that is far from the ball misses.
How do I pitch?
When your team is in the field you see the batter from behind the pitcher. Choose a pitch with the buttons (or the number keys 1 to 5), aim the target ring in or around the strike zone and press PITCH when the outer ring is small and green: the smaller the ring, the more accurate the throw. A pitch that ends inside the box is a strike unless the batter hits it, and one outside the box is a ball unless the batter swings at it.
What are the pitch types?
Baseball Ninja has five pitches. The fastball is the fastest and straight, the sinker drops and runs in, the curveball drops a lot and is slow, the slider breaks sideways and the change-up is slow to fool the batter. Throwing the same pitch again and again makes the batter ready for it, so mix them up, and use the corners of the zone with two strikes. A pitcher with a higher break rating makes sharper curves.
How do the count and the innings work?
A batter gets three strikes before he is out and four balls before he walks to first base. Fouls count as strikes until you have two. Three outs end a half-inning: your team bats in the top half and pitches in the bottom half. Quick games last 3, 5 or 9 innings, the Season and the Ninja Cup use 3. If the score is tied at the end, extra innings begin with a runner on second base, and the home team skips its last turn when it already leads. A lead of 15 runs at the end of a half-inning ends the game early (the mercy rule).
How does team building work?
You earn coins after every game. Open the team button to spend them: a Scout pack gives you a random new player, from common to legend, and an upgrade adds 4 to every rating of a player, up to level 5. Your batting order and your starting pitcher are chosen in the same screen. Power makes hits fly farther, contact widens your timing window, speed helps on the bases, eye is how well a batter sees pitches, and for pitchers velocity, control and break change the pitches.
What are the Season, the Ninja Cup, the Daily game and the Derby?
The Season is 8 teams from the Rookie Rockets to the Ninja Stars; beat one to unlock the next and earn up to three stars for each. The Ninja Cup is a knockout with 8 teams: win the quarter-final, the semi-final and the final to lift the trophy, lose once and you are out. The Daily game is against the same team and stadium for everyone on the same day, with a free leaderboard. The Home Run Derby gives you 10 swings to hit as far as you can.
Does Baseball Ninja have a leaderboard?
Yes. Quick games, Daily games and the Home Run Derby all send your score to one free leaderboard with two panels, This month and All time. The game sends your score together with a summary of the game, such as runs, hits, home runs and strikeouts, and the server checks that they add up, so only real games count. The Season and the Ninja Cup are saved on your device only.
Can I play on a phone?
Yes. Baseball Ninja works on phones and tablets in portrait and landscape. Drag one thumb on the field to aim, and use the big round SWING or PITCH button with the other. On a computer you can use the mouse, or the arrow keys and Space. You can pause with the pause button or the Esc key.
