Because your column is tiled with blue and red dots and your row is tiled with a yellow dot, the question mark tile should have purple dots. This gives us enough information to solve the puzzle: because the row that the question mark tile is in has a one-dot tile and a four-dot tile, and its column has a two-dot tile, the tile of the question mark must have three dots in it.
We also know that the dots in this tile must be blue or red, because it shares a column with tiles that have purple and yellow dots. Because the row the tile is in already has a single point tile, and since the column has two and three point tiles, we know that the tile in the upper right corner must have four points. Each tile has between one and four dots that are blue, purple, red, or yellow.įor this puzzle, we can start with the mosaic in the upper right corner. Similarly, in each row and in each column there cannot be two tiles with dots of the same color.
In each row and in each column, two tiles cannot have the same number of points. These puzzles require you to determine the number and color of the dots that belong to the question mark tile by reducing the possible answers to one tile at a time.
