A new brick puzzle inspired by the famous Einstein's riddle. You have a rectangular board and you need to arrange all tiles, so that all of them fit. The tiles are one, two or more columns wide. Drag a tile and drop it on the board.

Every color must only appear once in every row. The same color may appear multiple times per column. There are easy (3x3), normal (3x5 and 4x4), difficult (5x5) and very difficult (6x6) puzzles.You can get a hint, if you get stuck.
