Nudge may look like a bit of a brute, but that's all show. All the little blue guy really wants is to keep his beloved balloons safe. Personally, if we wanted to keep our balloons out of harm's way, we wouldn't leave them lying around mazes with moving blocks and walking mines, but that's just us. Help Nudge across 40 challenging levels in this charming and devious little puzzler!

Atomic Cicada brings us another original puzzle game, with a light math flavor, and an atmosphere somewhere between "excessively subdued and calming" and "horror film waiting to happen". Whether the game is trying to imply an ominous black cloud puzzle OF DOOM! or just a strange twisting of "relax" spelled backwards is completely up to you.

A gorgeous puzzle game with an impeccable user interface, Minim sets the standard for browser-based casual games. Minimize molecules to nothingness by combining atoms with digits on them, according to a few simple rules. Despite the references to chemistry and some light math, Minim isn't an educational game. It's more like a comforting hug followed by a knuckle sandwich.

Grid is a moody, deliberate puzzle game from two-man development team Atomic Cicada. Your job is to rotate the available tiles so that every space has power and none of your tiles have any unconnected ends. The catch is that you can only rotate a tile if it already has power flowing through it, which bumps Grid up a few notches on the thoughtfulness index.
