Imangi Studios resurrects their smash-hit iOS arcade game with this bigger, badder, and altogether better installment that keeps all the action you loved and buffs it up with an improved look and more. Once again, you've stolen a forbidden idol from a dangerous temple and have to run for your life, but with new locales, obstacles, power-ups, abilities, and much more in your way (including one very big, very angry monkey) you have your work cut out for you.

GYRO is a simple game of reflex-based color matching created by Submachine Factory. It's one of those games that are perfect for short bursts of play, providing ample amounts of challenge to train your reaction times and hand-eye coordination. Simply drag and rotate the circle on the screen (or use the bar at the bottom for fine control), moving it so its three color slices catch the appropriately colored particles floating in from outside. Capture more and you'll increase your score multiplier, but get one wrong and it resets. Now your only goal is this: score as many points as you possibly can!

When sliding through a blocky two color world, keep one thing in mind: Space is Key. Actually, if you're playing this painfully challenging arcade game on your iOS device, that title isn't as true. With the browser versions of Space is Key and Space is Key 2, all you do is tap the [spacebar] to jump, hence the name. On a touch screen there is no spacebar, so instead, your finger is key. That's a bit of an awkward title for a game, though, so instead of brain thinking, we'll game playing!

The revolution is here, and it's pink, furry, and packing heat! In this action-packed iOS platformer, players control Belle, a multiarmed gun-weilding alien, in her quest to free her kind from slavery. Making your way safely through the frantic, dangerous levels will require mastery of the tricky controls, but Project 83113 is a beautifully made and fun blast while it lasts.

ZONR, from the master if bite-sized iOS games Klick Tock, will engage you for longer than you'll care to admit. The simple reflex game is focused on quick recognition skills, challenging you to act fast, act decisively, and recover from your mistakes without hesitation. Stressful? Never! More fun than it ought to be? You bet!
