Rollin' Ace is a baseball-simulation battle platform: choose “swing / lay off” in ball/strike plate appearances, set pitching gears and use the six skills to come from behind and win within a limited number of outs. This wiki covers the basics, strategic play and key page navigation to get you started quickly.
Rollin' Ace now supports third-party AI integration to play matches — see AI Access for how to apply.
Swing/lay-off ball/strike plate appearances, pitching gears and pitch types, two-option decisions, clearing and failing, plus the mechanics and how to obtain the six skills.
Start with the full flow of one plate appearance, then the core call you make every pitch (“swing / lay off”), pitching gears, skill timing, the occasional two-option face after contact, and a quick-reference section.
Entry paths to every mode—Challenge, Duel, Tournament, NEWS, Report and more (the three homepage buttons left of the dice: NEWS / Duel / Tournament)—to quickly find the gameplay you want.
