Quadoku Solitaire

Oct 3, 2018

If you're not going anywhere for a few minutes, these quick-solve puzzles can exercise your mind without too much stress.
This App is a hybrid of Shidoku and Solitaire. Shidoku is like a beginner version of Sudoku, with only a 4x4 grid instead of the more complex 9x9. By itself, it is not so interesting, but using playing cards increases the difficulty and improves the visual experience.
