InZOI’s groundbreaking life simulation features nine distinct life stages for your Zois, each with unique characteristics and timeframes. Whether you’re raising a newborn or guiding a senior Zoi through retirement, understanding the aging system is crucial for crafting your perfect virtual life story.

Understanding InZOI’s Aging Mechanics
The game features a sophisticated aging system where Zois naturally progress through life stages as you play. By default, one in-game day equals 96 real-world minutes, meaning a complete lifespan takes over two real-life days of continuous play. Players can adjust day length in settings to speed up or slow down aging to suit their gameplay style.
All Nine Life Stages Explained
- Newborn (0-1 day) – The briefest stage where Zois remain in cribs
- Toddler (1-3 days) – Learn walking, talking and basic skills
- Child (4-10 days) – Develop personality traits and interests
- Adolescent (11-15 days) – Transition phase before teenage years
- Teenager (16-20 days) – Explore relationships and career paths
- Young Adult (21-30 days) – Prime for career and family building
- Adult (31-50 days) – Established life phase with career peaks
- Middle-Aged (51-65 days) – Physical changes become noticeable
- Senior (66-100 days) – Retirement and life reflection phase

Special Note on Unplayable Stages
Three life stages (Newborn, Toddler, Adolescent) aren’t available during character creation. These occur naturally when:
- Your Zoi has a baby (Newborn/Toddler)
- Child Zois grow into Adolescents before becoming Teens
Controlling the Aging Process
Players have two methods to influence aging speed:
- Adjust day length in game settings (shorter days = faster aging)
- Use life stage triggers like having children to progress generations
Why Life Stages Matter
Each phase unlocks unique:
- Social interactions
- Career opportunities
- Skill development options
- Appearance customization
- Life milestones and achievements
