Scalene Software has announced that Concentrix has been released via Xbox Live Indie Games, priced 240 MS Points ($3.00 / 2,79€ / £2.04). Concentrix is a unique action puzzle game played on a circular game board. Blocks fall outward from the center toward the perimeter of the playing area. Players can manipulate the falling shapes by moving or rotating them. The game challenges players because matching some blocks may block other matches. The eight play modes feature varied game mechanics. Different shapes may fall, such as simple groups of blocks or more challenging ring-like shapes. The player may be striving to match color or position. Each mode plays differently and is a unique experience.
