In the upper left corner of the game screen is a pixel picture.

You need to build the same picture in the frame in the center of the screen, using the blocks available on the right side of the screen for this.

Unlike Tetris, blocks can only be placed on top of other blocks, not on empty cells.

The blocks are dragged with the mouse. And they can be rotated.

• 50+ pixel pictures of various sizes and themes (people, animals, fruits, things, devices, etc.).
  
• Each of the pictures has 6 game variations - that is, with different sets of blocks and different complexity. Thus, there are 300+ levels in the game.
  
• The "Mosaic Easy" difficulty mode is an ordinary 2D mosaic, even a child can solve it. This cannot be said for all other modes. The most difficult one is "3D Hard", which has a high combinatoriness and a hard shortage of blocks. This poses a serious intellectual challenge (but all levels in the game are guaranteed to be passable).
  
• The game is non-linear! Many levels have many correct solutions (block stacking sequences), and not just one, conceived by the author of the game.
