after completed all goals ( the last goal is to build three businesses in town), then next task is to propose to a sim, and then engagement ring is given which you can purchase using simStone (30). Once the relationship is more mature, then POP the question, and now your sims are married!
Once you have married sims, now you can purchase baby crib for $10,000 or using simStone under "nursery", and wait around 35hr to get an infant sim.
Achieve a population milestone to receive 5LP, then delete an item to return to just under the milestone award. End the game using the Home button. Start the game again, and you can re-earn the LP award simply by buying another item. Repeat as often as you like.
shake your device for like 3-4 sec, then your sims will vomit. If the Sims only show nausea, give another 2-3 sec shake, it will definitely do the job.
Making a big purchase? Why not get a bonus luxury vehicle together!! Not only the Mansion is fully furnished with 2 bedrooms, 2 bathrooms, but it also comes with a 3-star car for your sim to drive.
Switch your language to anything else and exit & enter the plants, then you will see that the LP sprout is free.
NOTE: If you do this glitch a lot, you will get infinite items in your storage.
Enter the in-game store where you can purchase Simoleons and LP with your credit card. Exit the game by using the Home button on your iPhone while the game is still showing the "Connecting to the server" screen. Wait for at least 10 seconds, then start the game again. Be sure to cancel out of the store loading screen. Re-enter the in-game store and now everything should be free to purchase.
