Success Story is a fast-paced time-management title in which you have to flip burgers, salt fries, and serve desserts for a variety of famished customers.

In fact, there are more than 149 different recipes to master, 12 different burger components to slap together, and ten different restaurants for you to work in.

And in case you didn't already have enough on your plate (see what we did there?), there are ten boss characters that you'll have to defeat across a variety of mini-games.

HighFlyer DeathDefyer (i4) sees you strap on your trusty jetpack and set off across non-linear levels to discover rare treasures and new islands.

During this voyage of discovery, you'll encounter giant beasts and lethal deathtraps, and advance a story told through more than 100 pages of a comic book.

There are two playable characters to choose from, and a tasty 41 Game Center achievements to unlock.

Elf Defense is an extremely colourful (and extremely good-looking) tower defence title that pits you against more than 100 different enemies.

Luckily, you have your own selection of soldiers to help you out - all of which pack unique abilities. Plus, you can collect formidable mercenary warriors to bolster your army.

There's even an in-game shop from which you can purchase items and upgrades. These should help you defeat your foes. Don't blame me if they don't, though.
