The game of an increased level of complexity. Your score is equal the beginning of the game to some value, which depends on the sizes of a field and level of complexity. The game field represents four squares consisting of blocks of one type. In three seconds the blocks on a field mix up, and you can begin to play. It is necessary to you to restore source sort of a field. For this purpose it is necessary pressing on buttons placed on perimeter of a field, to move blocks. At pressing the button all appropriate line of blocks moves. The block, which is pushed out for bounds of a field is located on a released crate of a field. Each course reduces your score. If the counter becomes less than zero, the game comes to an end. On each round the fixed time lasts. If you have not placed blocks for this time, the game comes to an end. At transition the degree of hashing of blocks is increased by each new round. The degree of hashing also depends on the sizes of a field and level of complexity of the game. The hashing of blocks occurs in such a manner that always there is a way of their installation in a source state for the given number of courses. It is fair for all roundes, which number is less 42 ? 69, depending on the sizes of a field and level of complexity.
