This gives us sufficient information to solve the puzzle: Because the row that the question mark tile is in has a tile with one dot and a tile with four dots and its column has a tile with two dots, the question mark tile has to have three dots on it. Because the row that tile is in already has a tile with a single dot on it, and because the column has tiles with both two and three dots on them, we know that the tile in the top right corner must have four dots we also know that the dots on this tile must be either blue or red, as it shares a column with tiles that have purple and yellow dots on them. Each tile has between one and four dots that are either blue, purple, red, or yellow.įor this puzzle, we can start with the tile in the top-right corner. Similarly, in each row and in each column no two tiles can have dots of the same color. In each row and in each column no two tiles can have the same number of dots. These puzzles require you to determine the number and color of dots that belong in the tile with the question mark on it by reducing the possible answers one tile at a time.
