Amazon’s usual protocol for a free app is to give people something that costs a dollar or maybe two at the most. Today, they’re doing something special – giving away a $5 app for free in Eufloria HD. This relaxing game has seen respectable releases on the PS3 and Steam, and can now be yours at no cost. If you’re not usually a fan of something that isn’t fast-paced, give this a shot. You have absolutely nothing to lose right now, so free up some space if you need to and try it out on your tablet or phone. When you’ve got it on with some ear buds in, it’s an easy way to kick back and relax.
