Area 51 Defense is a sci-fi-themed tower defence title that charges you with overcoming waves of invading enemy forces over 51 missions and two game modes: Campaign and Survival.

You can defend yourself against 14 different varieties of deadly enemy by constructing five unique types of tower.

These towers, which all have a special ability, can be upgraded 12 times. This, unsurprisingly, increases their usefulness.

Cyclone HD is a skill-based game that puts your eye-hand coordination to the test and tasks you with winning a progressive jackpot.

You do this by successfully catching a rotating light, which, naturally, becomes more challenging as you work your way through the game's levels.

If you do manage to nab yourself a jackpot worth screaming about, however, you can share news of your victory on both Facebook and Twitter.
