This crazy mash-up of RPG and color-matching puzzle is gorgeous, fun, and addictive. Destroy groups of blocks and rotate the puzzle grid to fight monsters by falling on them from above with your drill lance spinning. Bigger and better than the first Knightfall in every way, with a fleshed-out story, creative boss battles, and more ways to build your character, Knightfall 2 is what a sequel should be.

Puzzle Defence is a charming mash-up of the SameGame play mechanic with RPG elements. Scary, adorable monsters are attacking your castle, and the only way to defend yourself is to match them together, puzzle/strategy-style. You just want to hug this game and tousle its hair.

A mash-up of casual gameplay from the match-3 and RPG genres, Knightfall plays like a cross between Mr. Driller, Same Game and Puzzle Quest. It's a well-balanced and well-executed game with a fun story mode and an unlimited purgatory mode to keep you coming back for more. Achievements add to the addictive quality that Knightfall will bestow upon you.

Monolist, from Japanese developer (or possibly super-powered spy team) Polygon Gmen, is what you would get if you took classic Space Invaders gameplay, multiplied it by three, strained it through a net made of Arkanoid bonus drops, and then sprinkled in nine hundred million bullets. Like a recreational energy drink, it's cool, refreshing, burning sweet, and highly caffeinated.

Ball Drop One, produced by Finnish developer Ville Helin, is an interesting blend of pachinko and pinball. Drop your ball into the playing field, trying to rack up as many points as possible. If your ball hits a skull ball or stops moving, it explodes and the round ends. Simple enough, right?

When the head of the Weardd Academy's School for Responsible Reanimation mysteriously dies in a fire, the students blame each other and take up sides. They summon up the undead and dispatch them into battle. Welcome to Corpse Craft: Incident at Weardd Academy, a new zombie game from the makers of Whirled that mixes real time strategy with block clearing to create a unique new game experience.

With DragonStone, dev studio PlayPond bravely mashed a marble-grouping game with a shoot-em-up, spray-painted it with a medieval fantasy theme, and literally turned the whole thing on its head. The result is an exciting and perilously addictive experiment, with the friendly face and high production values of a casual game.

Trying to describe a game using splendiferous prose just seems so... right-brained-centric. How discriminatory! Thus, as a public service to all you left-brainers out there, I hereby present this mathematical description: Retroid = (Pong + Gravity - 1 player + Ball² + 3Enemy) * 4 modes + Bob.

Fall in, troops! It seems we've got ourselves another attack on our hands. Menacing spiders are descending from the skies, and it's up to our platoon of cannons to stop them! We've got to divide our forces to gather bullets on one side, and shoot down the spiders on the other side, so you'll need to divide your attention to win the battle!
