- Refill sanity meter quicker
In the basement of the hotel, turn to your right. Go down the hall and enter the door at the end of the hall and you will be in a freezer. A piece of meat will be hanging from the ceiling. Go up to it and punch it. Your sanity meter will refill faster than normal.

- Rat Cave
When you go in City Hall, do not bother building the 'Rat Cave'. Tristan Legend will build it at no charge with additional progress in the game; however if you do build it, it will cost 3,000 Simoleons.

- Walk slowly
Set the Nintendo DS system time ten minutes behind. Then, go back into the game. Somebody will call and say that you are an alien, and you will be able to walk very slowly. Take a shower to make the effects wear off.

- SSX 3 reference
Go to the shop in Strangetown. When you enter the shop, go to the left side where you see boxes on a shelf. Look closely to see the box art from SSX 3.

- Getting things finished quicker
To get things done quicker, change the internal clock on your DS system. This trick works well if you want to get rooms built faster. Instead of waiting the normal eight hours, just set your clock ahead eight hours. If you need money get guests to stay, set clock forward the desired number of hours or days.

- Sink into floor
Notice: Save the game before attempting this trick. Go into Jebidiah J. Jerky's room, located in Saloon near the restroom. Run into the corner where the orange toolbox is found and keep running to sink into the floor. Notice: Do not save the game after this happens.

- Free milkshake
Go to the part of town where all the cows are found. Go up to the cows, not the bull, and tip it over. After tipping it over and it is lying down, select 'Milk' to get a milkshake. If you just milk the cow without tipping it, you will get plain milk. You can sell it for 2 Simoleons at the store, drink it, or give it away as a gift.

- Mummified Alien
Go into the Desert with your Metal Detector. Find the crashed space ship and use your Metal Detector in that area. You should get a Mummified Alien, worth 375 Simoleons.

- Fast Social
Notice: Save the game before attempting this trick. This trick can only be done if you have Optem Alfred living in your penthouse, and if you have every room built (including the Bovine Shrine). Set the Nintendo DS system date to October 31 (Halloween) of the next year. Rebegin the system and begin the game. You should have several messages. One of them should be the cashier at your hotel. He will say that a friendly ghost came to the hotel. If you do not get this message, change the date to one year in the future again and rebegin. Check for the ghost in these locations: Art Gallery, Mamma Hogg's Saloon, Hotel Lobby, Atrium, and Basement. When you see him, go to a person nearby and do a Social with him or her (Impress, Calm Down, etc.) while close to the ghost. He will watch and make the Social go faster. When the mini-game is done, you will now make the social go faster for every person you socialize with. Go up to the ghost. To the right side of the screen you will see the words ' Mood neutral' and there will be two selections which are 'xxx Ofix mood social xxx' and 'Give gift'. Select the first option. Notice: If you select 'Give gift' your Sim will enter the Wight Abyss and not be able to get out. Your interaction with anything will not show up. Do not enter any doors or the game will freeze. Instead, reset the Nintendo DS and you will begin where you saved, but will still speed up interactions. The game will also be odd and you will find new people. Notice: Repeating the process may delete your saved game file.

- Stop wires from getting chewed
In order to have the mole or worm stop chewing on the wires, spray it with water several times.

- Additional aliens
To get more aliens on your save, set the system clock forward by one minute. Load your saved game and walk around for a minute. Save the game, then set system clock back to real time. The bellhop should say that you are a time traveler and that the aliens have launched a full scale attack. When you see the clock, touch it or you will lose all your sanity.

- Increase stats
When you get your Hotel score to 100% and obtain at least four stars for your Hotel goals, go to the computer in your room and check out all stats to get an outfit. You can do this a total of three times, but afterwards your stats will keep getting raised. Also, you must have a good relationship with Mama Hogg and the Goth chick.
