Rule 1: You have to make a map with at least one inverted rollercoaster. This inverted rollercoaster has to be of the inverted rollercoaster type, so not a compact inverted coaster and no inverted vertical shuttle. You are allowed to do crazy stuff with it, like making a launched version or make a dueling version. You are allowed to change the track type, but the trains have to be the 4-across inverted coaster trains.
Rule 2: The deadline for this contest will be on Wednesday the 26th of June, 2019!
Rule 3: In this round, you are not allowed to use custom scenery and objects. You are only allowed to use objects from the base game and its expansions. There's one exception in this round: You are allowed to use a custom palette! You can either use one you found somewhere or you can make your own. I have made a tutorial on custom palettes you might want to check out. https://www.youtube.com/watch?v=2epMQ_6tU1s
Rule 4: Maximum map size for this round is 40x40 tiles.
Rule 5: You are allowed to put 3 extra functioning tracked rides, like a car ride, river rapids, mini golf or an extra inverted coaster, and 3 extra functioning rides with a base, like a launched freefall, a merry go round or a maze. With a functioning ride, i mean that the ride is either Opened or in Test mode.
Rule 6: You are allowed to put unlimited amounts of trackitecture. These trackitecture rides all have to be closed.
Rule 7: The most important rule: Have fun!
