About DIAMOND NINE 野球監督・育成シミュレーション

This is a baseball game where you become a manager and develop your team. Scout players, decide on your batting order and pitching staff, and press "Advance Year" to complete a 143-game season all at once.

For those who enjoy the manager mode of baseball games but don't have time to play through each game individually, this baseball training simulation allows you to develop your team season by season during your breaks.

Check your rankings and performance, strengthen your weak points, and move on to the next year. Like a professional baseball pennant race, you'll progress from winning the domestic league to competing in overseas leagues.

■ How to Play
- Acquire player cards one by one through scouting to build your team. Domestic and overseas players will appear, with an overseas player guaranteed every 30 scouts.
- The "Areas to Strengthen" section on the scouting screen displays players with low overall scores in the batting and pitching staff.
- Team formation is divided into two tabs: "Fielders" and "Pitchers." Assemble your 9-man batting order and consider your starting pitcher, reliever, and closer (if you're unsure, use "Auto-Formation").
- Tap a player's name to see detailed information on their batting, power, speed, throwing arm, fielding ranks, and special abilities.
- Use points earned in matches to reinforce and awaken your team. Drawing the same player will increase their abilities.

■ Aim for the Pennant and Championship
- Winning the domestic league for three consecutive years allows you to challenge the overseas league. Reaching the top overseas opens up the Space League.
- The standings display wins/losses, win percentage, game difference, as well as runs scored, runs allowed, and run differential.
- "Goals and Achievements" displays today's goals, season goals, and past achievements all in one place.
- Daily login bonus. You'll receive a notification at night if you don't play (you can choose to turn notifications on or off).
- Share your drawn player cards and championship records with images.
- Limited-time events are also held.

■ No Waiting Time
- There is no waiting time or limit on the number of times you can "Advance a Year". You can continue playing as long as you like. ■ For people who:
・Like baseball games and professional baseball
・Like baseball training simulations and baseball games where you manage a team as a manager
・Are looking for a sports game that can be played in short bursts during free time
・Want a baseball game that can be played offline (matches can be played without an internet connection. An internet connection is required to display ads)

■ Ads and In-App Purchases

Watching an ad allows you to draw a scout once per day. Within the app, you can purchase points used for scouting and awakening, as well as a one-time purchase "Premium Pass" (full-screen ad-free, double points earned in matches, 5,000 points daily, 30,000 points at the end of each season). You can check the scout drop rates at any time in the "Drop Rate" section of the scouting screen. Scout probabilities and match results do not change with purchases.

Game progress is saved on your device. Please export your save data from the settings before deleting the app.

This is an unofficial simulation game.

What’s new

Version 1.5.0 · Updated November 5, 2026

大事な試合(開幕戦・短期決戦の第1戦と王手の試合)の前でホームに止まり、順位や成績を見てから札の「監督して戦う」「一気に進める」を選べます(設定で止まらないようにも)。監督の試合はボールや走者が動き、1画面で結果まで見られます。打者は右・左の打席に立ち分けます。長打狙い・直球中心などの作戦は打者ごと・投手ごとに1タップで出せ、効いたかが実況に出ます。守備交代は位置と守備の評価つき。試合中は能力が見え、打率・防御率・奪三振・球数が動きます。打球音は木のバットに。スカウトを10回まとめて引けるようにしました(値段と確率は1回ずつと同じ)。試合の画面を作り直し、投球や守備・走塁が本物の球場の広さで動きます。監督の試合は始める前にスタメンを決められます。 ストアの評価のお願いを、優勝した時や初めて金・虹のカードを引いた時だけにしました。設定に作者のほかのアプリの欄を足しました。シェアした時の文のリンクを Google Play のページにしました。
