Circulate

This colorful, unique puzzle game offers a number of stimulating brain-twisters. The basic gist of Circulate is this: you must rotate a sphere to rearrange similar-colored balls so they re all in one place. Each time you solve a puzzle, you re awarded a number of points that allow you to skip over easier levels. Every level has a different-themed board with pleasant graphics, and if you choose to play in full-screen mode, you ll see vibrant, psychedelic colors morphing in the background. While you can t configure the game to play with your keyboard, you can adjust the volume of the music and sound effects, decide whether the cursor should flash, and determine how quickly the sphere should rotate. Puzzle fans who like variety should at least take a look at Circulate.
