I absolutely love head-scratching puzzle games, and Minim fits the bill. Gameplay is simple: you match connected molecules by number, making them disappear until you clear the board. The levels themselves are not so simple. Once you make it past the basic learning-the-ropes intro levels, you'll find your rotating the board and resetting the puzzle, trying to find the one move that will unravel the whole thing.

As the game progresses, new twists appear in the game. There are blue connections that let you swap adjacent molecules, addition and subtraction molecules that change the numbers on the board, and other monkey wrenches that generally make the puzzle harder. Minim may require minimal skill to play, but it requires some creativity to beat.
