Welcome to part 2 of the Jurassic Park Builder iPhone game guide. Click here to go back to part 1.

After you build roads to complete missions and you no longer need them, you can delete them just as easily. To do this, click on the Roads icon in the lower right corner. Then, in the lower left corner you will see a “Remove” icon. Tap on that one, and then start tapping on the roads that you want to remove. Watch them disappear right before your eyes after you do this.

There are a ton of missions in this game that relate to simply moving dinosaur pens and other buildings around, which make for easy money, but what do you do if you do not want to mess up the order that your buildings are already in? Simply tap on the dinosaur pen or other building, press the ‘move’ button, and then without moving the building in question, hit “accept” and the game will act as if a move has been completed, thus allowing you to complete those missions.

If the harbors stop letting you collect from them for any reason, first, make sure they don’t need to be upgraded. If they do, then upgrade them. If not, then zoom in and tap on them up close, because sometimes the game has a hard time detecting taps on small objects. If that still doesn’t make anything happen, look at the updates section in your app store and see if there are updates available for the game. If not, then try to tap them again just to make sure, and if that still doesn’t work, then delete the app, download it again, and restart it.

If the game won’t let you expand without spending Bucks on it, then you need to complete more missions. Once enough missions are complete, then you will be able to unlock the expansion and buy it using regular coins.
