The original puzzle with vague rules (largely due to the fact that they never explained), and the ability to simultaneously play up to four people (in the absence of living their opponents quite successfully replaces the computer). On the playing field located thirteen gray columns, which players will fill in turn making moves. Each participant is given a four-square-block, each distinguished by a color and pattern depicted within them. You are required to choose one of the blocks and put it in any of the columns. The next block will be put on top of the previous one - and so on, until the column is over space. Instead spent issued a new block, with a random combination of pattern and color. To win you need to score more points than the opponent. Points are awarded on a rather tricky scheme, but operates one basic rule - the bigger your unit is similar in color and pattern on the blocks around, the more points will be given for it. For example, if you put a square on a blank space, then nothing will earn. And if there is one square of the same color, then the reward will be 15 points. If there will be more single-color squares, then the result will increase. And if you're lucky and the same will not only color but also pattern, the number of points obtained could easily pass for a hundred. Strategic element is enhanced by the fact that each player is known not only for its own set of squares, but also blocks issued for opponents hands. With proper care it allows you to control the game and eventually get an advantage. Naturally, no one stops to deny the enemy the best combination, putting their units on them prepared positions. Among other interesting opportunities present team game, and, as in the single-player mode, you can play in a pair with a person or a computer. Moves still committed to the queue, but in this mode, two players are working on a common pool of points.
