How to Play
The Daily Loop
Each day has 4 time slots (Morning, Afternoon, Evening, Night). Spend them on:
- Training — Pick one of five shots and play its minigame. Each session pays training currency (Power, Quickness, Technique, Mind), mostly in what that shot is made of, and more for every clean rep.
- Development — Spend currency on stats. Every stat has a recipe, and points cost more as a stat climbs past 40, 60 and 80.
- Matches — Play friendly matches against opponents at your level, or enter tournaments for bracket-style competition with story events woven into each round.
- Rest — Recover energy. Running out of energy limits what you can do.
- Story Events — Narrative moments trigger based on your stats, relationships, and career progress. Your choices have real consequences.
Matches
Matches simulate point-by-point using your stats. At critical moments — break points, set points, match points — you make tactical decisions that influence the outcome. After each match you earn experience, training currency (split by how each part of your game went), and sometimes items or abilities based on your performance.
Every shot of every rally is calculated using your stats (and your opponent's stats) and used in a cascading sigmoid function to generate realistic outcomes. Incoming shots of high quality require higher quality responses to continue the rally, while lower incoming quality means better opportunities for offense. Playstyle factors into both tendencies and chance of success.
Progression Systems
- 14 Stats across Core, Technical, Physical, and Mental categories (all 0–100), bought with training currency on the Development screen. Every point matters.
- Equipment — Equip a racquet, shoes, outfit, and hat for persistent stat boosts. Use consumables for energy recovery and temporary buffs before activities.
- Abilities — Passive bonuses ranging from Common to Legendary rarity. Bought in the shop for XP plus the currency their effect draws on, or earned through challenges and the story.
- Challenges — Objective-based goals (reach stat thresholds, win matches, build relationships) that reward items, abilities, XP, and training currency.
Storylines
Five branching narrative arcs unfold as you play:
- Coach — Learn fundamentals from Coach Gonzalez and unlock advanced training techniques.
- Rival — A competitive relationship with Jordan that pushes you to prove yourself.
- Romance — Meet Alex at a tournament and build a relationship through shared experiences.
- Family — Navigate support and pressure from your parent as your career develops.
- Career — Agent recruitment, sponsorship deals, and the professional circuit.
Your choices in story events pay or cost training currency, and shape your relationships and which future events become available.
Tips for New Players
- Watch your energy — Training and matches cost energy. Don't burn out right before a tournament.
- Perform well in matches — A good match pays more currency, and pays it in what you did well.
- Equip items before matches — Even small stat boosts add up in close matches.
- Explore story choices — Different decisions open different paths. There's no single "right" answer.
- Match your playstyle — Train the shots that pay for the stats your playstyle needs, and spend there first.
