The developer of Gold Award-winning LostWinds 2: Winter of the Melodias, Frontier Developments, has just released a new iOS title called Coaster Crazy, which allows you to build your very own white-knuckle attractions.
Your overall aim in this RollerCoaster Tycoon-style simulation is to travel across the globe and build a variety of coasters that are wild, fast, and frantic enough to send shivers down the spines of the world's biggest g-force-loving adrenaline junkies.
You can create 3D coasters of all different shapes and sizes simply by dragging your finger along your device's display.
Your inventions can be wild modern masterpieces made from steel or rickety wooden deathtraps that look like they're about to collapse at any second. They just have to be fun to ride.
As you progress through Coaster Crazy, you'll gain access to new track pieces, coaster cars, and themed scenery, which you can use to spruce up your attractions and bag more cash and gems from your excited punters.
If you build a coaster that you're particularly proud of, by the way, you can upload it for the rest of the world to enjoy.
Coaster Crazy is a free download, but you can spend real-world cash on in-app purchases to speed up your progress. If you like.
