Today's list is once again entirely made up of games, but there are a few high profile ones that have never been free before. We also have a game that is available for free in both its iPhone and iPad form.
Addicus ($1.99 -> Free): A math-based puzzle game that will have you frantically tapping mushrooms.
In the top left-hand corner of the screen is a number and color that you must match before time expires. The playing field consists of mushrooms of different colors with numbers on top that you must tap to add up to the required number. If the number in the top left-hand corner is white, you can use any of the mushrooms, otherwise it must be mushrooms of the specific color. If you tap the wrong color, add up the wrong amount, or run out of time the game is over.
Addicus features an endless number of levels, the ability to gain multipliers and combos, and OpenFeint integration.
Addicus is available for free today only (5/21).
BioDefense ($1.99 -> Free): A game that features a mix of RTS and tower defense.
In the game you are required to defend your base from attacking zombies by placing floodlights to brighten up the playing field so you can actually see your foes and then utilize your towers to take them out. You will also need to collect resources in order to upgrade your defenses by capping toxic pools.
The game features 10 missions, survival mode, six enemy types with different behaviors, and OpenFeint integration.
BioDefense is available for free today only (5/21).
Jet Ball ($4.99 -> Free): An
Arkanoid-like brick breaker.
Your standard brick breaker with solid controls and great graphics. In the game you control your paddle via a small circle beneath it. You are able to fire the ball and any of the power-ups you collect by tapping anywhere above the paddle. The idea, of course, is to clear the level of all objects without missing the ball.
The game features 65 levels, three levels of difficulty, tons of different power-ups and types of bricks, and OpenFeint integration.
Jet Ball is available for free today only (5/21).
CosmoBlast ($.99 -> Free): A puzzle game with expanding and exploding planets.
This one requires you to remove all planets from the board by making them expand and explode. A single tap will expand a planet while using up one move. If a planet is red, the next tap will make it explode, sending off bursts of energy in all directions. If the energy hits another planet, that planet will expand as well or explode if it is red. By strategically exploding planets you can remove others from the board without using up moves. Run out of moves and the game is over.
The game features three levels of difficulty, power-ups, and online leaderboards.
CosmoBlast is available for free for a limited time.
Devil Invasion ($.99 -> Free): An RPG matching game where you must defend your castle.
The game is kind of like a less complicated version of
Puzzle Quest. You must match three or more like colored pieces via hexagonal movements in order to gain mana and the ability use one of your powers, or match like action pieces to instantly attack. As long as you defeat the oncoming forces, you can move on to the next level and use your points to upgrade your attacks.
The game features tons of different upgradeable spells and OpenFeint integration.

BioDefense HD ($2.99 -> Free): Just like its iPhone counterpart detailed above except the camera is zoomed out much further to take advantage of the extra screen real estate.
