The Blergs are a happy, adorable, square-shaped race of creatures with a problem: They've been infected with a disease that turns them into nasty, green Gerblins. Professor Blerg has created a potion that can cure the disease, but only you can decide who should get it. Give a dose to an infected Blerg and he'll be cured and removed from the board, along with all the other Blergs around him. But if a healthy Blerg takes it, he'll be instantly turned into a Gerblin and escape from your grasp.

Gerblins is a logic-puzzle game that's equal parts Minesweeper and Tetris, bundled with plenty of grinning cuteness, a catchy soundtrack and just a touch of Mr. Yuck.
