As an Android user, one of the best perks is the Amazon Free Paid App of the Day.

Everyday, Amazon offers a paid Android app for free. Even better: these apps aren’t like the many useless apps that are usually free in the Android Market, but many times they are actually really good apps and games. In the past, they have offered apps like Guitar Hero, Plants vs Zombies, and Doodle Jump– apps that usually cost from $1-$10 — for free. In fact, today, they are offering the game 3D Bio Ball HD for free. It’s a twist on the classic game Labyrinth where you guide a ball around a maze to a target.

So how can you get these apps? Instructions after the break.
