Relationships unlock perks, gifts, and unique scenes. Focus on one main character at a time for the fastest route to higher affection levels.

SimGirls 66 is famous for its secret scenes. Here is how to unlock the major ones:

  • The "Final Girl" (Kerry/Police Girl):

  • Gallery Passwords (For the Museum):

    • Based on developer notes and community testing:

    | Bug | Symptom | Fix | |-----|---------|-----| | Affection not saving | After reload, girl resets to 0 | Manually save in two slots; avoid quickload | | Gift duplication | “Loved gift” can be given twice | Patch intended; restart game resets counter | | Stress not decreasing | Park action does nothing | Sleep 8h first, then park works |

    Because v6.6 is an RPG hybrid, the early game strategy is different from the classic version:

    Phase 1: The Early Grind

    Phase 2: The Girls

  • Phone Calls: You must call the girls to set up dates. If you ignore them for too long, their affection will decay.

    • Phase 3: The Time Machine

    Old guide thresholds shifted by ~5 points upward for Tiers 3–4 to slow progression.

    SimGirls 66 (often labeled as the Diamond Version or Build 66) represents one of the most polished and expanded versions of the legendary dating simulation/RPG. Unlike the original "Classic" version, this build includes the Black Custom path, improved graphics, hidden characters, and a streamlined relationship system.

    This guide covers the critical updates in this version and provides a strategic walkthrough to maximizing stats and winning the game.
