11Overview22The Adult life stage is the prime working and family-building period of a Zoi's life in inZOI. It begins when a Zoi ages up from Young Adult and ends when they transition to Middle-Aged. At approximately 20 in-game days, the Adult stage is the longest single life stage outside the Senior stage and represents roughly ages 30 to 50 within the game's progression system. With full access to careers, relationships, pregnancy, marriage, and business ownership, Adult Zois can pursue any goal in the game without the temporary restrictions that affect younger or older life stages.44Adult is one of six life stages selectable in Create a Zoi, alongside Child, Teenager, Young Adult, Middle-Aged, and Senior. The other three stages (Newborn, Toddler, and Adolescent) are reachable only through gameplay aging.66Duration88The Adult stage lasts approximately 20 in-game days at default settings. By comparison, the Young Adult stage that precedes it lasts 9 days, and the Middle-Aged stage that follows lasts 16 days, making Adult the longest single non-Senior stage by a meaningful margin.1010At the default Length of Day setting of 48 real-world minutes per in-game day (introduced in the October 2025 Update), the Adult stage covers roughly 16 real-world hours of continuous gameplay. Players who use the alternative Length of Day options (96 minutes, 4 hours, or 24 hours per in-game day) can extend that real-time duration without changing the in-game day count.1313StageIn-Game DaysReal-Time at Default (48 min)Young Adult9approximately 7.2 hoursAdult20approximately 16 hoursMiddle-Aged16approximately 12.8 hoursSeniorup to 35approximately 28 hours maximum1515Career Access1616Adult Zois have unrestricted access to every career path in the game. Most jobs require Young Adult, Adult, or Middle-Aged status, so the Adult stage falls in the middle of the working life window without any age-related job restrictions.1818Career-related rules during the Adult stage:2020Idol Trainee retirement: The Idol Trainee career path retires when a Zoi ages up from Young Adult to Adult. Idol Trainees who have not transitioned to a regular career by the time they become Adults will lose their idol position. This is unique to the idol path; all other careers carry over normally.Career switching: Adults can quit and switch careers freely without the age-out penalty. New careers can be started at any time using the Career App on the Smartphone.Promotion progression: Adults can climb to the top rank of any career. The 20-day duration provides enough time to reach maximum rank in most rabbit-hole jobs and many active jobs, though high-skill careers (Pro Gamer, Lawyer, University Professor) often benefit from earlier skill investment during the Young Adult stage.Business ownership: Adults can purchase, build, and operate businesses across all 9 business types added in the v0.5.0 update.2222Family and Relationships2424The Adult stage is the most common stage for major family milestones.2626Marriage: Adults can propose, marry, and host weddings. The marriage and wedding system supports both same-sex and opposite-sex partnerships for player-created Zois.Pregnancy: Female Adults can become pregnant. Pregnancy lasts approximately 3 in-game days and ends with the birth of a Newborn.Adoption: Adults can adopt children through the in-game computer or laptop. The adoption system was added in the v0.2.0 (June 2025) update.Parenting: Adult Zois are typically the primary parents in a household. The Adult stage usually overlaps with their children's Toddler, Child, and Adolescent stages, making this the prime parenting window.Family expansion: Households can hold multiple generations during the Adult stage, with grandparents (Senior stage), parents (Adult/Middle-Aged), and children all coexisting.2828Skills and Hobbies3030Adult Zois have full access to every adult skill in the game. The 20-day duration provides ample time to reach high levels in multiple skills, especially for players who started skill development during the Young Adult stage.3232Skills that benefit most from the Adult stage's longer duration:3434High-tier creative skills like Art and Instruments that take longer to reach maximum levelCareer-supporting skills like Charm, Critical Thinking, and ProgrammingHobby skills like Gardening, Cooking, Baking, and Drink MixingCrime skill, capped at level 5, can be developed through criminal careers added in v0.5.03636Physical Appearance3838Adult Zois have the standard adult appearance with no special wrinkles, graying, or stamina penalties. Body shape continues to be affected by the body weight simulation system added in v0.2.0, which adjusts a Zoi's silhouette based on diet, exercise, and lifestyle. This means an Adult who consistently uses the gym and eats well will retain a fit appearance, while one who skips fitness routines may show weight gain.4040Unlike the Senior stage, where age-related appearance changes are applied automatically, the Adult appearance is fully customizable through Create a Zoi. Players can use the editor to adjust face, body, hair, and clothing for an Adult Zoi at any time during the stage.4242Needs Management4444All eight needs (Hunger, Hygiene, Sleep, Bathroom, Fun, Social, Recognition, Energy) operate at standard rates during the Adult stage. There are no stage-specific need decay modifiers, in contrast to the slower Energy recovery seen in the Senior stage.4646Personality traits and characteristics still influence individual need decay, but those modifiers are tied to the Zoi's trait selection rather than the Adult life stage itself. See the Needs article for the full list of needs and their gameplay effects.4848Aging Up5050Aging from Adult to Middle-Aged occurs automatically at the end of the 20-day duration unless aging has been disabled in the Simulation settings. Two pathways trigger the transition:5252Birthday celebration: If the player throws a birthday party with a cake, the Zoi can blow out candles to age up. This unlocks a brief celebratory moment with household members.Spending the birthday alone: If no party is held, the Zoi ages up naturally on their birthday. There is no penalty for skipping the party, though the celebratory interactions are missed.5454After aging up, the Zoi enters the Middle-Aged stage. The transition is instant: the Zoi's age category updates and any age-restricted interactions become available. There is no special cooldown or restriction immediately after aging up.5656Disabling Aging5858Players who want to keep a Zoi in the Adult stage indefinitely can disable aging through Game Options under Simulation. There are two separate toggles:6060Disable aging (My Zois): Stops aging only for Zois the player controls. NPCs continue to age normally.Disable aging (All Zois): Stops aging for every Zoi in the world, freezing the entire population at their current life stages.6262These settings can be changed at any time. A common pattern is to disable aging during the Adult stage when the Zoi is at the height of their career and family commitments, allowing players to enjoy the most active gameplay window without worrying about aging into the Middle-Aged or Senior stages.6464Creating an Adult in Character Creation6666The Adult life stage is one of six options available in Create a Zoi. When starting a new Zoi, players can pick Adult from the Profile section. A Zoi created as an Adult will begin gameplay at the start of the Adult stage with all 20 potential days ahead of them, plus the full 16 days of the Middle-Aged stage and up to 35 days of the Senior stage.6868Adult is the default and most popular starting stage for players who want to play through the full career, marriage, parenthood, and aging arc without spending real-time hours in the Young Adult or Teenager stages first.7070Tips7272The Adult stage is the longest non-Senior stage at 20 days. Use it as the main career and family-building window.Idol Trainees retire when transitioning to Adult. Plan a career switch before aging up if your Zoi is on the idol path.Pregnancy is most common during the Adult stage. The 20-day duration easily accommodates multiple pregnancies if desired.Skills started during Young Adult continue to level during Adult. The longer stage gives time to reach max level in several skills.Business ownership is a strong Adult goal. The 20-day stage provides enough runway to build a business that will provide income through the Senior stage.If you want to extend the Adult stage indefinitely, disable aging in Simulation settings. Re-enable aging when you are ready to transition to Middle-Aged.The body weight simulation system continues during Adult. Regular fitness activities help maintain Zoi appearance.All adult interactions, including all crime and the full social system, are available during this stage.7474See Also7676Life Stages lists every life stage with cumulative day counts.
