The Sims Mobile: All About Households

One of the most important things to know about The Sims Mobile is that households do not work the same way as they do in The Sims 4.

When you start the game, you have two possible household slots for Sims, with two more being purchasable with SimCash. This might lead some players to think that you’re forced to spend real money to have a household of more than two Sims, but this is not true. Your Sims can have multiple children and grow large families even with just two household slots.

The household slots represent Sims that are playable by you, not necessarily Sims that live in the home. More than four Sims can live in the home at a time, but you can only directly control up to two of them. If you choose to spend SimCash, you can control up to four of them, but this is not necessary to play the game the way it was intended.

Here’s a breakdown of how household slots work when it comes to marriage and children:


When your Sim gets married, their spouse will move into the house with you. If you have a free household slot, you will have the option to make their spouse playable in the family portrait. Making your Sim’s spouse playable will use up a free household slot.

If you do not have any free household slots available when your Sim gets married, you will not be able to make their spouse playable, but they will still move into the home. Your Sim can still interact with them the same way they interact with any other Sim. You just cannot directly control the spouse’s actions.

The exception to this is marrying a Sim that is being played by another player. Read on to find out how relationships with other players’ Sims work.

TIP: After unlocking the second household slot, the game will prompt you to create a new Sim to move into the household as a playable Sim. This Sim will take up the second household slot. Many players prefer having their initial Sim marry this second Sim. Your second Sim is already playable and living in the house, so marrying them is the most straightforward choice.


Children cannot be made into playable Sims until they become adults, so even if you have an extra household slot free when you have a baby, you won’t be able to assign them that slot. This means you don’t need to have any available household slots in order to have children. It also means you can have more than two children if you’d like.

When a child becomes an adult, you’ll be able to promote them to a playable Sim through the family portrait. Promoting an adult child will take up a household slot and that child will become playable. If you have no available household slots for them, you will have to wait until your current Sims become elderly and retire in order to free up a household slot.

Extra adult children that you don’t want to make playable or have hanging around can be moved out, instead. If you have more than four children, you’ll have no choice but to move out some of them when they become adults, since you cannot have more than four playable Sims at a time.

Other Players’ Sims

Understanding how relationships with other players’ Sims work is very important. They don’t follow the same rules as NPC Sims do.

Your Sims can marry the Sims of other players, but since these Sims belong to another player, this means they will have to leave that player’s household to join yours. When you ask another player’s Sim to move in with you, the other player will receive a request, asking them if they would like to send their Sim to your household. If the other player accepts, the Sim will leave the house and they will lose control of the Sim. By asking another player’s Sim to move in with you, you are essentially asking that player to transfer ownership of that Sim to you.

If you accept a request to have your Sim move away to someone else’s household and have no other Sims left in your household, you’ll be taken to the CAS screen and see a notification informing you that a long lost cousin has come to live in the home. You will be able to customise this Sim to your liking just like any other Sim in your playable household.

TL;DR Version

All of that can seem confusing, so to break it all down more simply:

  1. Household slots are playable Sims, not necessarily Sims that live in the house.
  2. You can have more Sims living in the house than household slots.
  3. Your playable Sims can still interact with other Sims living in the house.
  4. Only adult Sims can become playable Sims.
  5. Other players’ Sims can be married and moved into your household, but keep in mind this means that the other player will lose control of their Sim.
