The objective is to arrange the tiles in the center of the board to match the ones displayed along the game-area border. However, you move the tiles in groups of four or more by spinning them with a control located in the corner where four tiles touch. Similar to a 2D Rubik's Cube, Cyclanoid is harder than it looks since you must get the tiles aligned without disrupting your previous work. It also includes a built-in visual puzzle builder for creating your own games. The graphics are attractive, and MIDI-based music and crisp digital sound effects add to the fun. Plus, an automated demo shows the movement options of the more complex games. When you purchase, you'll get access to over 20 different puzzles, with various board sizes and skill levels.
