Coastle

Coastle takes the guess-and-compare format of games like Poeltl and applies it to roller coasters. Each day there is one mystery coaster, picked from a list its maker chose by hand. You type the name of any coaster, choose it from the list of coasters and parks, and the game lays out its stats in a row next to the answer's.

Each row has seven columns: country, manufacturer, seating type, number of inversions, height, length and top speed. A tile shows whether that value matches the answer or, for the numbers, whether the answer is higher or lower. After your third turn you can reveal the first letter of the coaster's name, and after your fifth the name of its park. You have six turns in all. The stats come from Captain Coaster's database, and the page warns that a few coasters have missing values.

The daily changes at midnight UTC. Once it is done you can copy your result or look at charts of your daily and endless records. Endless mode then serves random coasters, with a Harder Endless option in the settings and a metric units switch. It suits theme park fans who know their Intamin from their B&M and like a numbers puzzle more than a picture one.
