"The Sims 4": Complete Guide to Create-A-Sim (Cas) Mode

Kenzie needed a quick escape from real-life pressures, and found "The Sims 4." She now enjoys playing, writing, and YouTubing the game.

Create-A-Sim (CAS)

To create a unique Sim, it all starts here.

How to Use Create-A-Sim (CAS)

Create-A-Sim (CAS) is where every game starts in The Sims 4. This mode is where you create your character(s) who will be your avatars in the game. To make your game as fun as possible, you'll want to create Sims with just the right look and personality to fit the kind of storyline you want to play. If you're new to CAS or have never given much thought to it before, here are some tips for making the most of this mode.

The CAS Screen

When you load a new game, you will be taken directly to the blue CAS screen so you can make your characters.

The first option you will have is to take a fun quiz so that the game can create a Sim for you. This is story mode, which can sometimes help to jump-start your creativity. For now, though, click the "no thanks" option, so you can learn to create a Sim from scratch.

The game will then throw a random starter Sim up on the screen. You can tweak this Sim a little, or completely transform them.

You Have to Have the Game to Play

Laying the Foundation

Choose features such as your Sim's gender, overall appearance, age, voice or walk style.

The Basics to Creating a Sim

The controls in the upper-left corner of the screen allow you to choose some basic details about your Sim. Let's go through these options.

Name: Click the line that says, "Hello, my name is..." to give your Sim a first and last name. If you prefer, you can click the die symbols to randomize the names.

Sex and Gender: Click the plumbob (diamond) symbol to reveal these options. Choose your Sim's sex (male/female), but it doesn't have to end there. The Sims 4 is a very inclusive game, allowing you to create Sims who are cisgender, transgender, androgynous, or you can blow gender expectations out of the water.

Click the three dots beneath the sex symbols, and you'll have the option to:

  • select whether your Sim has masculine or feminine features, or prefers masculine or feminine clothing styles (regardless of chosen sex).
  • decide if you want your Sim (of any sex or gender or style) to be able to impregnate other Sims, or get pregnant. This means either male or female Sims can impregnate others or get pregnant, based on your preference. If your Sim doesn't want children, you can click "neither."
  • You can also choose whether or not you want your Sim to be able to pee standing up, which is an amusing detail.

Age: Your Sim can start as a toddler, child, teen, young adult, adult, or elder. Babies cannot be created in CAS; they have to be given birth to in-game. Toddlers and children will require another Sim in the household to be a teen or older before you can start playing.

Walk Style: Click the right-hand square box in this menu to select your Sim's walk style. This can add a lot to your Sim's personality, and there are some very comical options as well.

Voice: The line with the candy, music symbol, bird, etc. is what you click for different voice styles. You can try out all the options. Use the slider to make the voice deeper or higher. Play around with this until you're satisfied.

Relations: The final box on this menu allows you to choose the relationship between your Sim and other Sims in the household. You won't be able to use this box until you add more Sims to the household, which we'll do in a bit.

Traits: Your Sim gets to start with up to three traits (children and toddlers only get one, and teens get two). Traits are what give your Sim personality. Click on the hexagons to see the different categories and review your options. Note, some traits automatically bar you from choosing others (for example, your Sim can't be flirty and unflirty simultaneously). If you prefer, you can click the die symbol and have your Sim's traits randomized.

Aspirations: Your Sim's aspirations will help define his or her goals in life. Throughout the game, you can change aspirations as much as you like, but the one you choose here will be important because it will give your Sim a bonus trait. Click on the hexagon and browse through the aspirations, paying attention to the bonus trait your Sim will get from it.

Make Your Sim Unique

Let's Make Your One-Of-A-Kind Sim

Start customizing your Sim by clicking their head. This click will bring you to a menu so that you can control all the details. Let's take a closer look at all the menu options:

Face: Choose a basic face shape for your skin, then use the sub-categories to alter the details. You can select things such as the slop of your Sim's forehead, the definition of his cheekbones, or the fullness of her lips. Select eye shape and color, eyebrow shape, and color, as well as little skin details such as scars, wrinkles, or beauty marks.

Hair: Select a style and color of hair for your Sim.

Facial Hair: This option appears below hair for male Sims only. You can choose from a variety of mustaches and bears, or have your Sim clean-shaven.

Detail Edit Mode: I'm skipping over to the left side of the screen because this is the best time to employ this part of the menu if you want to fully customize your Sim's features. Click this option and use your mouse to click and "grab" any part of your Sim's face you want to tweak. Make the nose longer, the chin more narrow, give the brows a steeper arch, or enlarge the eyes to give your Sim an innocent, doe-eyed look.

Hats: Give your Sim a hat, turban, costume mask, or other types of headgear.

Accessories: Customize your Sim with facial or ear piercings, necklaces, or glasses.

Make-up: Apply make-up to your Sims to complete his look.

360° Arrows: Grab and turn to see your Sim from all angels.

Style Your Sim

Move on to your Sim's body to shape it and clothe it as you like.

Give Your Sim Just the Right Style

When you're done customizing your Sim's features, click somewhere off your Sim on the blue screen to zoom out to the body menu. Here, you can customize your Sim's body type and begin deciding which fashions are just right for this character.

Let's look over this new menu:

Body: Lets you choose a basic body type/shape for your Sim.

Muscle and Weight Slider Bars: Lets you adjust your Sim's body shape.

Styled Looks: Choose from some pre-made outfits for your Sims.

Tops/Full Body/Bottoms/Accessories/Footwear: Choose individual items to dress your Sim.

Sub-categories: Narrow down the type of item you want. For example, in the "tops" menu, you can select from sub-categories of blouses, t-shirts, jackets, etc.

Outfit Types: Allows you to save and categorize your Sim's looks. You can create everyday looks, formal outfits, sporty styles, sleepwear, party outfits, swimwear, warm weather outfits, and cold-weather outfits. You can have up to five of each type of outfit.

Items with Swatches: You can see the item you are choosing, and if you click on it, you will open a small menu offering options for the different colors and/or patterns for which that item is available.

Filters: you can filter items by color, materials, outfit categories, styles, or even your favorite game packs. The only default filters are masculine or feminine, but by turning those off, you will get a greater variety of options with no limits.

"Sims Spark'd" CAS Challenge: Gender Not Required

Create an Entire Household

You can make a traditional family or a diverse group who barely know each other—it's all up to you.

Creating an Entire Household in Cas

While you can certainly start a game with just one Sim in your household, you might wish to add more. You can have up to eight Sims in a single household. Click the "Add a Sim" button on the bottom left corner to see the menu options.

Play with Genetics: Marked by the DNA symbol, this option generates a Sim that is a blood relative of other Sim(s) in the household. It'll give the Sims similar features. When the menu opens, the Sim pictured is the one of whom you are creating the relative, so choose whether you want to create that Sim's parent, sibling, or child.

If you're creating a child, it will give you the option to select someone else in the household as the other parent, or you can leave this option blank. If you're creating a sibling, you can opt to make him a twin to your Sim. When you're done, select the checkmark, and you can go on to customize that Sim if desired.

Add a Sim from the Gallery: Clicking the folder will open up the gallery so you can choose from Sims created by other Simmers, or choose a Sim saved in your library.

Add an Occult Sim: Click the creepy swirl to create an alien, vampire, mermaid, or spellcaster Sim. All but the Spellcasters have a second form—their occult form—which you can customize as well.

Add Pet: Allows you to create a pet for your household. Pets may be a cat, dog, fox, or raccoon. Pets count towards one of the eight household slots. You can also add blood relatives to your pets by clicking on them and clicking "Play with Genetics."

Add a New Sim: This is for when you want to add a non-related Sim at random to customize from scratch. This is a great way to create a spouse, BFF, or roommate.

Add a Sim via Story: Clicking the bottom storybook symbol allows you to start over with the story mode quiz and create a Sim that way.

Creating a Household

This is the "De La Cour" household, which can be found in the Sims 4 user gallery. They are a quirky, creative and fun family—very edgy—and dream of fame.

Remaining Menus

Tying It Up

As I mentioned previously, across the bottom of the screen you'll find arrows that allow you to undo and redo actions.

Randomize: You will also find a triangular arrow with a die symbol; if you click the triangle, it'll give you a checklist of features. Check or uncheck any you like and click the die to randomize these particular features.

Randomize from Gallery: The photograph symbol with the die on it will, when you click it, change the current Sim to a random Sim selected automatically from the user gallery.

Save Household: On the upper right corner of the screen, you'll see the folder symbol. This allows you to save your household to your library, or to the user gallery.

Open the Gallery: The photo symbol allows you to open the library and gallery so you can browse it and select Sims from it. The shortcut for this function is F4.

Notification Wall: The message icon is not necessary in this mode, but it's there if you want to take a peek mid-game.

Options Menu: three dots, when clicked on, will bring you to the game menu.

Play: When you're done creating Sims, click the checkmark on the bottom-right of the screen to enter the game. It will then allow you to find your family a place to live so you can start playing.

Make sure you're satisfied with your Sim at this point! Once you exit the CAS mode here, you will not be able to change your Sim's gender, voice, walk style, traits, age, or most of their features unless you use cheats.
