How to play: Blok Us is played on a square board divided into 20 rows and 20 columns. There are game tiles organized into 21 shapes in each of four colors. Game tiles are based on free polyominoes of from one to five squares. The first piece played of each color is placed in left-bottom corner of the board. Each new piece played must be placed so that it touches at least one piece of the same color, with only corner-to-corner contact allowed—edges cannot touch. However, edge-to-edge contact is allowed when two pieces of different color are involved. When a player cannot place a piece, he or she passes, and play continues as normal. The game ends when no one can place a piece. Features: - No Annoying Popup Ads - Strong AI in Short Time - Beautiful Graphic - Continue Your Game after Break - Top Score List
