Welcome back again!
Task: Claim your daily bonus at least 10 times. (Does not have to be 10 in a row. Save before leaving to ensure credit is given.)
Task: Build a tracked ride primarily using the "Advanced editor".
Completion suggestion: Try using ALL basic track elements (chainlift, boosters [if available], and brakes) correctly to help count for credit or use only the "Advanced Editor"!
Reward: Spinning coaster
Task: Get at least $100,000 money. (Through any means possible, whether that means gaining it through the park, or purchasing it from the store.)
A worthy park!
Task: Get a park value of at least $200,000.
Completion suggestion: The Water alterator is the most expensive element in the game, (Unlocked with "Explore the world with swans!") therefore placing just 6 of these will increase your park value to over $200,000.
Task: Get a park value of at least $400,000.
Completion suggestion: The Water alterator is the most expensive element in the game, (Unlocked with "Explore the world with swans!") therefore placing just 12 of these will increase your park value to over $400,000.
Spin to win?!
Task: Build a spinning ride that can spin faster than 360deg/s. (Spinning rides include the spinning coaster, river rapids, and dark ride. There must be an entrance and exit on the ride. The ride must be ran through at least once on testing or open mode to get credit.)
Completion suggestion: Try creating a coaster that reaches the default height limit, then drops down using wide spiral down pieces ("More pieces" menu) to create a helix. Lower a large section of terrain for more spiral pieces. The spirals will cause the ride vehicle to spin rapidly when traveling on a straight section, and even faster when traveling on a turn opposite to the direction of the helix.
Nice and tidy!
Task: Have at least 100 visitors (value unconfirmed), 25 (value unconfirmed, achievable with 25) trash cans, and no trash in the park.
Explore the world with swans!
Task: Create a swan boats ride that goes around the perimeter of the park (1 block in) and open it. (This requires all park sections purchasable with in-game money unlocked. Turns can use the "Sharp turn" pieces but it is not imperative.)
Completion Suggestion: Build the ride underground or above the park.
Reward: Water alterator
The big picture!
Task (not developer confirmed): Build a square of 3 by 3 square borderless image panels and have each using a different image. Only works with the white image panels (which work like walls or fences), not the black ones (which are centered on the tile).
Task (not developer confirmed): Place four fire ball rides in a tower chain pattern.
Completion suggestion: Dig a 6x6 hole all the way to the lowest point on the map. Place a fire ball in the middle of the hole. Build an adjacent one around the center of the First fireball. Repeat this process until you have four in a chain formation (shown on the right). Note that in order to fit the four fire ball rides with the default height limit you must dig down, as four fireballs cannot fit starting from the ground. holding control in the spot you want the fireball allows you to move the fireball up with relative ease.
Use the T button to lift the ride 2m over the next one. Center the rides.
Reward: Light orb
Mega duck invasion!
Task: Place at least 100 mega ducks close together in a pond.
Have 100 mega ducks at least closed together.
Completion suggestion: Build a large pond and place the ducks, you can take as long as you wish.
For the extreme children!
Task (not developer confirmed): Create a junior coaster that reaches both the default height limit and the lowest possible depth with a minimum top speed of around 65km/h. (40 MPH)
Completion suggestion: First, use the terrain editor to dig a trench large enough for the coaster to go down to the lowest possible depth and come back up to ground level without touching the terrain. Once there, guide the coaster to a flat, open area where you can use chainlifts to bring it up to the height limit. Then, using the advanced editor, make the steepest drop allowed straight into the hole. The ride operations gamepass can make this easier to achieve. The ride has to be legacy, not improved.
Task (not developer confirmed): With 80+ guests in the park, prevent all of them being able to leave by blocking or deleting all paths to the exit. Achievement awarded when all current guests want to leave.
Completion suggestion: Deleting the single path in front of the exit will trap all current guests in the park. Alternatively, use any one way doorway to allow guests into your park, but not exit your park. Closing the rides along with increasing prices, or just closing the park, will encourage guests to leave.
Task (not developer confirmed): Kill ten guests on a ride at once (This requires a custom track ride that can have 10 or more guests on it at once that does not correctly complete a ride cycle).
Completion suggestion: Wait until your park has at least 80 guests. Make a continuous station about 50 cells long, putting the entrance at the far end from where the trains wait to be loaded, open the ride, and close all other rides in the park. The train cannot depart til all guests are seated, the length of the station makes it easy to get ten guests on the ride.
To the moon!
Task (not developer confirmed): Create a launched coaster that launches a car vertically upwards on a 90° incline (of which does not end) with a speed of least 190 km/h. The coaster then needs to be run through at least once and the cart must break.
Completion suggestion: Achieve high speeds with boosters. A 90° incline is achieved by using the smallest "up" piece, then the second "up" piece, and then the vertical "up" piece. The cart must break in order to get the achievement. The Ride Operations game pass will make achievement easier. (Note: This achievement requires at least the Flying coaster, therefore "The Park is growing" must be attained first.)
