Fairway Solitaire HD

Combine solitaire and a golf course, and you have exactly what this strangely addictive casual card game amounts to. Additional club upgrades and "hazard" challenges add some spice to each card layout, which acts as a "hole" on a course that gets scored like a regular golf game. Fairway Solitaire -- like many App Store freebies, lately -- charges an additional $2.99 for a ton of courses, but the free version's got eight courses plus a tutorial that offers plenty of replay value.
