LEGOLAND is an educational game that shows how to build a good park. You get the job as a park manager at a LEGOLAND Park. Professor Voltage creates a time machine, and when showing it to all the other park employees, the time machine breaks and the park blows up. As park manager you, the loudspeaker man Johnathon Ablebody, and Professor Voltage have to rebuild the park and make it better than before.
Johnathon will give you five tutorial levels to show you the main aspects for a good park, after you've finished all of them you will have to pass twelve levels. In these levels you will have four themes LEGOLAND, Wild West, Castle and Adventure to pick for attractions and scenery you will have to build around your park. The park will need to have enough of everything: shops, scenery, rides, food stores and, most importantly, a power station to give everything power. In the beginning you have ten chances to pass an appraisal by the main park inspector and ten minutes in between each appraisal, though you get fewer appraisals in later levels. The park also has gardeners and mechanics to water plants and fix rides needed for repairing.
The game also features a free play game, where their are no appraisals to pass, infinite money and you can design the park anyway you want. There are also clips showing what the LEGOLAND amusement parks in California, Windsor and Billund are like.
