Coastle
What is Coastle?
Coastle is a daily guessing game where players try to identify a mystery rollercoaster. Each day a new coaster is selected from a hand-picked list, and players have six attempts to guess it using clues about its attributes.
How to play Coastle
Type a coaster name into the search box and select the coaster or park you want to guess. After each guess, tiles indicate whether the answer is higher or lower than your guess for certain attributes, or if they match. Hints become available after turns 3 and 5.
Tips & strategy
- Use the higher/lower comparisons to narrow down the coaster's height, speed, length, and other numeric attributes.
- Pay attention to non-numeric clues like country, manufacturer, seating, and inversions to eliminate possibilities.
- Save your hints for later turns when you have fewer options left.
- Since the list is hand-picked and biased, consider well-known or popular coasters first.
- If you're stuck, think of coasters from major parks like Islands of Adventure or Phantasialand.
