Prize tokens come from side jobs and games
Certain side jobs reward Prize Tokens alongside coins and cards, but the primary source is dominating Baseball Card matches. Complete all available side jobs in the P.I. Office to snag extras without relying solely on games. Save before “Glugging from the Deep” ends, as “Jack Squat” locks out the hub—reload if needed to grind.

Key locations in P.I. Office hub
The P.I. Office serves as your central hub in Mouseburg, housing the Little & Big bar where everything happens for this unlock. Head to the bar counter for Baseball Card games, and spot the glowing Spike-D’s Prize D-Spenser vending machine nearby—it’s right in the bar area for easy access after token farming.

This spot stays open until the point of no return, so prioritize it amid case investigations and collectible hunts.
How to play and win Baseball Cards
Access the game at the P.I. Office bar or Roadhouse bars by interacting with the table for 50 coins per match.

Wins net one Prize Token each; aim for 20 minimum, but push to 30 for the “S’all in the Cards” trophy. Collect Baseball Cards throughout missions (buy misses from the shop later) to build a strong deck—ban weak cards once unlocked.
General rules for every turn
Play one player card and one tactic card per turn from your hand of five. Discard up to two unwanted cards to redraw. Strength (white circle) decides turn winner; ties go to coin flip. Tactic cards boost strength, speed, or fielding.
Batter phase scoring details
Start as batter to rack up points. Beat pitcher’s strength to advance your runner(s) by speed value spaces. Strength 3+ ignores speed for a home run—clear all bases. Opponent’s fielding subtracts from your speed (e.g., speed 3 minus fielding 2 = 1 space), but home-to-first always moves at least 1, and homers ignore fielding.

Pitcher phase defense strategy
Switch to pitcher to halt opponent scoring. High strength stops their advance outright. Fielding slows them even on their wins (e.g., their speed 2 minus your 2 = no move). Prioritize high strength to block homers; position fielding to trap runners on bases.
Deck optimization tips
- Collect all Baseball Cards via missions; shop fills gaps.
- Ban low-strength cards to draw powerhouses.
- Stock tactics boosting strength/speed for batters, fielding for pitchers.
- Save grinding late-game: more coins (1,500+ needed), better cards.
