Singles

In Singles there must be at most one number of the same value in each row and column. Your goal is to figure out (with help of logical deduction) which numbers should be marked. The puzzles can be solved in a step-by-step manner, and you should never have to guess. Singles is free and contains 128 puzzles in 4 different sizes, from 5x5 to 8x8. The game includes both a Swedish and an English version.
