Yakyu24 is a lightweight baseball simulation built around a simple choice: take the player on the card, or pass. Your challenge is to balance talent with the positions your club still needs.
Draft nine batters
Cards appear without a guaranteed position order. You have five passes for the batter draft. Running out never changes the quality of the remaining deck. Dynasty mode lets you undo your immediately preceding choice; the same card returns, not a new roll.
Fill the rotation and bullpen
Next, draft six starters and nine relievers. Each initial pitching phase has three passes. The final roster has 24 distinct players. Rotation order and bullpen roles can be changed before the season begins.
Set order and defense separately
Tap a field position to choose a player. Selecting someone already in the lineup swaps positions; selecting a benched hitter replaces that slot. Drag the batting order or use its arrow buttons. Auto-assignment rearranges your current nine; it does not draft new players or guarantee wins.
Watch or fast-forward
Choose the player pool independently of the interface language: NPB has 143 games, MLB 162 and KBO 144. Watch or fast-forward the same seeded season; playback speed does not affect results. Tap a completed game for innings. Daily challenges use NPB only.
Keep the story going
NPB uses 12 fictional clubs in two leagues and a simplified CS. MLB has 30 fictional clubs and KBO 10; both use a custom top-four playoff. These are not official schedules or competition formats. In dynasty mode, the offseason leads into another year with the same club.
