You need to sign in before playing. Each account gets its first 3 lives free through the ending. Creating a character, being reborn or continuing as a child each counts as a new life; reloading or resuming a save does not. From life 4 onward, free play stops at age 30. A one-time $9 Full Game Pass unlocks play beyond 30 for this and future lives, with no subscription. Character saving is also available during free play.Read the full guide

Compare the available careers’ requirements and income with your expenses, debt and family commitments. Read the financial effects of each decision instead of choosing by salary alone.

Pay attention to health changes and the risks described in each event. Some opportunities cost health as well as money. Illness and accidents can end a life early, even if you have made careful choices. Review the event history for what happened in this life; there is no guaranteed lifespan.Read the full guide

At the ending, use the continue-as-a-child option when a child is available. The new character has their own life, influenced by family background and the previous generation. The inheritance calculation accounts for the estate, heirs and inheritance events; it does not transfer all parental money directly at birth. Starting a separate character is a different option.Read the full guide

Check your connection and login, then try online saving again. Local progress that has not synced cannot be recovered from another device. If a conflict appears, load the online version or keep the local progress in a separate slot.Read the full guide
