The Sims 4 is the fourth main installment of the popular life simulation game series, The Sims. And just like its predecessors, it allows its players to control the life of Sims and the relationships they build in the game. This includes their physical attributes, their life goals, career choices, friends, partner in life, and just about anything one can think of.

Each Sims installment also comes with numerous expansion packs, game packs, and stuff packs that allow the player to further customize the life of their Sims. For The Sims 4 expansion packs, players are allowed to pursue new careers in social media or build their own retail store or restaurants, which wasn't available in the past franchise. For its game packs, players are not only allowed to go on vacation, but also create paranormal Sims!

However, what really makes every The Sims game a fun is all the things you can do with your Sims. With the touch of a few buttons, you can turn around the life of your Sims completely and watch them go ballistic or be absolutely horrified with the sudden changes. And that is exactly what this list is all about, trying the weirdest cheats you can do in the game and how to do it.

These are not just the favorite “motherlode” cheat or postponing their birthdays, so they can enjoy more time in each life stage. This includes stranger ones like forcing a Sim to get pregnant or instantly killing a Sim out of too much embarrassment. Just don’t forget to hit the save button before trying the cheat so you can quickly go back to their normal life after.

20 Make Everyone Immortal

The Sims 4 Sim Crying Over Dead Sim
  • Cheat: Death.toggle

Ah, immortality. Most of dream of it, but chances are no one will ever achieve it. Except, of course, when it comes to your Sims. They can exist and live forever, prosper for all eternity if you so choose. Sometimes, even the long lifespan option just isn't enough to complete all their aspirations and dreams.

That's why this cheat is pretty useful, and a bit extreme. It essentially prevents death in your game. The best part is that it will prevent any accidental deaths, but it's nice to know dying from old age is also now an impossibility.

19 Spawn A Random Friend For Your Sims

  • Cheat: relationship.create_friends_for_sim

If your Sim is utterly unlikable or just struggling hard to make any friends, you might feel tempted to just plop a friend down for them from the skies above. After all, why spend all the time and effort trying to please your neighbors when you can just automatically have a friend made for you?

Thanks to this cheat, a random Sim who's now friends with your Sim will spawn on the lot. It's a handy little tool that prevents you from having to make custom Sims from scratch and then manually grind their relationship level. With this, your Sim can have as many random friends as they'd like.

18 Become An Unstoppable Vampire

The Sims 4 Vampire Charming Sim
  • Cheat: bucks.lock_all_perks_for_bucks_type 40962 {simID} false

One of the greatest gameplay features introduced in The Sims 4 was vampires. The skill tree and special powers are very rewarding, and the gameplay can keep you engrossed within the game for a long time. Overall, there's very few cons to playing a vampire especially once you unlock powers that allow you to walk in sunlight.

However, with every strength becomes a weakness. Boring, right? Well, not to worry, because this cheat will let you get rid of your weaknesses while still keeping all of your vampire powers the same. Your Sim is now absolutely unstoppable.

17 Put A Curse On Any Sim

The Sims 4 Cursed Sim
  • Cheat: trait.equp_trait_curses_(cursename)
  • Curse Names: TouchyFeely, InfectiousLaughter, Repulsiveness, WildMagic, NightStalker, SweatyStench, FountainOfMagic, PunchableFace, HexOfDuelist

The Realm of Magic game pack introduced spells and spellcasters into the game, which really is a great way to bring more chaos into your Sim world. Curses in particular are a fun little addition that can make a Sim's life incredibly miserable. Better yet, curses don't just disappear on their own, they need to be removed with a specific way.

Curses act as traits in the game, so you can just use the trait cheat and add in "curses" after to specify the trait type. There's a total of nine different and equally horrible curses to choose from, so whatever misery you want to put your Sim through, there's plenty to choose from.

16 Make The Perfect Specimen

The Sims 4 Sims Hugging
  • Cheat: stats.set_stat lifeSkillStatistic_(lifeskillname) 100
  • Options: Empathy, Manners, Responsibility, ConflictResolution, EmotionalControl

Nobody's perfect, unless you choose to make them so. The greatest fun from the Parenthood game pack comes from being able to shape your Sims into the person they are through rigorous parenting and guidance. However, sometimes, it's just nice to have the perfect specimen.

Thanks to this cheat, you can turn any Sim into an absolute angel. They'll always have their manners and emotions in check, and feel for other Sims. They act responsibly as well. Or, if that sounds boring, you could also do the opposite, and turn them into unlikable monsters.

15 Completely Destroy The Relationship Of Two Sims

The Sims 4 Fight
  • Cheat: relationship.destroy {yoursimID} {targetsimID}
  • Get Sim ID Cheat: sims.get_sim_id_by_name (first name) (last name)

Relationships are a big part of the game, but in the always-happy world of Sims it can sometimes feel like there's a bit too much sunshine and too many rainbows. Thankfully, there's a few evil things you can do the spice things up on top of this cheat.

This hilarious cheat is best used on Sims that are blood-related, best friends or even in a relationship. Upon the activation of the cheat, watch both Sims quickly have a change of heart and act as if they’re sworn enemies.

14 Instantly Kill Sims by Over Exhaustion, Electrocution Or Embarrassment

The Sims 4 Electrocution
  • Exhaustion Cheat: sims.add_buff buff_death_elderexhaustion_warning
  • Electrocution Cheat: sims.add_buff buff_death_electrocution_warning
  • Embarrassment Cheat: sims.add_buff buff_mortified

Just like in real life, Sims can die from accidents, hunger and old age. But did you know that a Sim can also die from too much work, getting electrocuted and even embarrassment? It might sound bizarre, but there are some pretty unique ways of dying in the game.

However, the keyword for over exhaustion can only be used on elders while the keyword electrocution will only work when the Sim repairs an electronic item after inputting the keyword. Of course, you can still do the classic death due to hunger that is triggered by using the keyword “sims.add_buff buff_motives_hunger_starving”.

13 Force A Sim to Give Birth To Multiple Children

The Sims 4 Pregnant Lady
  • Cheat: pregnancy.force_offspring_count (simID) (count)

Giving birth to twins or triplets is a must-experience in The Sims 4. However, wouldn’t it be more fun if your Sims could give birth to quadruplets or more? Good thing there is also a cheat for this and you have the option to choose how many children your Sim will give birth to. Just input the keyword “pregnancy.force_offspring_count (simID) (count)” and add the number of children you want the Sim to give birth to.

Just make sure the number of children you choose does not exceed the maximum number of members allowed in one household or you will experience stability issues. Each household can only have a maximum of eight members, so the Sim can give birth to as many as seven kids when they're alone in the household.

12 Make A Sim Into A Ghost

The Sims 4 Drowned Ghosts
  • Cheat: sims.add_buff Ghostly

Aside from making a Sim into a vampire (which we'll cover later), you can also temporarily change them into a ghost. This can be triggered by using the keyword “sims.add_buff Ghostly” in the cheat console. And if you’re looking for a bit more fun, you can also make the ghost Sim appear to be pregnant from the first to third trimester, and even do a fake birth. Unfortunately, no babies will be born using this cheat.

To activate these cheats, input “sims.add_buff Buff_Pregnancy_Trimester1”, “sims.add_buff Buff_Pregnancy_Trimester2” and “Sims.add_buff Buff_Pregnancy_Trimester3” to make the Sim pregnant from the first, second and third trimester, respectively. And to give the fake birth, input “sims.add_buff Buff_Pregnancy_InLabor” in the cheat console. The best thing about this cheat is that it’s only temporary, so you can bring the Sim back to their original form anytime.

11 Poison Your Sim

The Sims 4 Poisoned Sim
  • Cheat: traits.equip trait poison

If you have Jungle Adventure installed, you're in for a special treat. A new death type for introduced in the game pack: death by poison. If you need to quickly get rid of a Sim or would simply like to see someone suffer, simply punch in this cheat.

This cheat works similarly to the curses, meaning it's actually a trait given to the Sim in question. Just make sure to save your game before you watch your Sim collapse from deadly poisoning.

10 Instantly Turn Your Sim Into A Grand Master Vampire

The Sims 4 Vampire Burning In Sun
  • Cheat: stats.set_stat rankedStatistic_Occult_VampireXP 1486
  • Kill Vampire Cheat: traits.equip_trait Vampire_Sun

One of the weirdest things you can do in Sims 4 is to turn your Sim into a vampire. However, it’s not really as easy as you think because players need to do a series of tasks before they can reach the grandmaster level. The maximum level allows the Sim to unlock secret skills and abilities for vampire Sims, so it's really worth trying.

It's a good thing there’s also a cheat for that, so you don’t need to do all the work to get there. And if you ever get bored, you can also instantly kill the vampire Sim through the power of the sun with a cheat.

9 Make Your Sim Act Like A Maid Automatically

The Sims 4 Maid Doing Laundry
  • Cheat: sims.add_buff NPC_Maid
  • Remove Cheat: sims.remove_buff NPC_Maid

Hiring a maid in the game can be a bit expensive, particularly when you’re not using the “motherlode” cheat. But did you know that there’s a cheat that makes a Sim automatically behave as a maid? Upon using the cheat, the active Sim will automatically do anything that needs to be cleaned like doing the dishes, cleaning the bathroom, and just about anything that falls under the duties of a maid. And when there’s nothing left to do, the Sim goes back to their normal self.

This cheat is best used when you don’t have a maid and you’re about to throw a birthday party, wedding, or just have a few friends over. And once that’s all done, you can easily bring the Sim back to normal with the keyword “sims.remove_buff NPC_Maid” as if nothing ever changed.

8 Have An Alien Infect Your Sim

The Sims 4 Infected Sim
  • Cheat: traits.equip_trait Infected

The Strangerville game pack not only brings you a mysterious story your Sim can follow to find out the truth about a local lab, but also the abundance of infected people. These possessed Sims will walk around Strangerville with a creepy frozen smile on their face and blabber all sorts of nonsense.

It's actually one of the creepiest features in the game, and the best part is that you can make any Sim infected with this cheat. If you ever wanted to play with a possessed Sim, now you have the opportunity. Pair it with some paranormal gameplay and magic, and you have a truly spooky world in your hands.

7 Make Your Sim Sick Or Act Weird

The Sims 4 Sick Sim
  • Cheat: sims.add_buff Giggly_mild / Sims.add_buff Giggly_severe
  • Cheat Options: Replace "giggly" with "itchy"

Once you get the Get to Work expansion pack for The Sims 4, you can use cheats that will make your Sim sick for some hours. This includes coughing, sneezing, being dazed, and a lot more. The good thing about these cheats is that they only last for two to three hours, so it doesn’t really make any permanent changes to your Sim.

And if you want to do something crazier, you can also make your Sim giggle and itch for three straight hours. Just imagine how funny it would be if you did that on their wedding day, or during a first date.

6 Turn Your Sim Into A Global Superstar In One Second

The Sims 4 Sim Signing Autograph
  • Cheat: testingcheats on, then click on a Sim while pressing SHIFT

Imagine becoming a superstar in a blink of an eye. It's possible, so long as you have Get Famous installed. Usually, you'd have to work hard for a Sim to become even remotely close to a global superstar rank. It takes immense amounts of grind and many gigs.

The better way is to just manually upgrading your Sim's fame rank. Make them the superstar they deserve to be, with five stars in just one second.

5 Bankrupt Your Sim

The Sims 4 Homeless Sim Sleeping On The Bench
  • Cheat: sims.modify_funds {+/- amount}

Almost every Simmer has probably already used the "motherlode" cheat to make their Sim very rich. With unlimited money, you can buy the biggest house and have as many cars as you like. But have you ever tried the cheat to make your Sim bankrupt? If you try the cheat "sims.modify_funds {+/- amount}," you can set the amount of Simeleons your Sim have, even at a negative value.

And if you want to be crueler, you can force their bills to be due and demote or get them fired from their work at the same time. To make the bills due instantly, just use the keyword “household.force_bills_due” and watch how your Sim slowly gets stressed with how much they need to pay.

4 Makes Friends With All The Sims, Including The Dead

The Sims 4 Group Of Sims
  • Cheat: relationships.introduce_sim_to_all_others

Improving the relationship of your Sim with other Sims is crucial for success in their careers. However, sometimes, the amount of work to do that is just too much, so you can just modify their relationship using a cheat for instant results.

But unbeknownst to many, there is also a cheat that will instantly make them friends with all the Sims in the game, including their ex, enemies and even the dead! Aside from having exceptional social skills, this will also result in a Sim crying over a dead Sim they have never met. As soon as you use it, you will see all your social relationship improve, whether they’re dead or alive.

3 Make Your Child Rebellious

The Sims 4 Rebellious Child
  • Cheat: traits.equip_trait ChildhoodPhase_Clingy
  • Cheat Options: PickyEater_A, Loud, Rebellious, Bear, MeanStreak, Distant

After getting the Parenthood expansion, you can activate different cheats that will alter the behavior of a kid or teen. This includes making them clingy, picky, loud, mean, distant, and even very rebellious! Each trait is completely different, so it’s worth trying each of them just for the experience.

One trait that’s worth trying is the rebellious one, as it really makes it hard for the parents to handle the kids. Keep in mind that the clingy and bear trait will not work for teens, while the distant trait doesn't work on children.

2 Add A Random Sim To The Household

The Sims 4 Household Photo
  • Cheat: relationship.add_bit {yoursimID} {targetsimID} {relationshipBit}
  • Relationship Options: romantic-Married, family_husband_wife, family_grandchild, family_son_daughter, family_brother_sister, family_grandparent, family_parent

Another weird cheat you need to try is adding a random Sim into your household. It can be a vampire, alien or any Sim you like. And that’s not all, you can even assign them to be related to anyone in the household. This includes being a spouse, grandchild, son or daughter, brother or sister, parent, or even a grandparent!

This means you can assign someone younger than your Sim to be their parent or grandparent, which would be a really funny scenario.

1 Increase The Chances Of Fire

The Sims 4 Sims On Fire
  • Cheat: sims.add_buff BurningLove / objects.gsi_create_obj 0x0000abd9
  • Remove Cheat: Sims.remove_buff BurningLove

Probably the craziest thing you can do in the game is to spawn fire to different Sims or things in the game. This includes making a Sim combust anytime and removing the default timeout after a recent fire incident so the fire just keeps happening. This means your Sim will spontaneously be on fire and can die if you don't have a shower nearby.

Another alternative is to randomly set fire to a spot close to your Sim that will not affect them or the objects near it. It's a way to see your Sim panic without risking their lives.
