It's now possible to paint pictures as pretty as any by Monet or van Gogh without even having to pick up a brush-just use your mind! Put those logic skills to use on these paint-doku puzzles from the mind-boggling geniuses at Conceptis Puzzles. Puzzle lovers start with blank canvases that have numbered rows and columns; these numbers are the key to determining which squares to shade in. When solvers have cracked the code, they'll have "painted" an octopus, Albert Einstein's portrait, a Brazilian carnival celebration, and more.
