The purpose of this game is solve it without cheats or hints. It’s designed to help promote thinking patterns , and this company has ruined its design. ### 5/5 — Works a different part of your brain *2025-04-03, version 1.11* Fun… ### 2/5 — Great idea. Needs more design work *2024-10-02, version 1.11* I love the concept of this game but it feels unfinished design-wise. *The dots in the circles need to be removed. I don’t care if it is an original tile or not. Just fixing this would make it much much more playable. * The colors in the bottom left box need to grey out or disappear when you’ve placed all one color, just like in your regular sudoku game. * Grey scale colors need to be used instead of green to represent neutral things (like the box backgrounds of other like colors in the game.) You can replace the grey pieces in the game with another color like teal. It has the potential to be an awesome game! ### 4/5 — Great until ads *2024-06-06, version 1.10* This was a great game until the ads started to be animated. I’m done with ads. I’m willing to pay for an app that doesn’t have ads. ### 5/5 — LOVE this app *2023-12-11, version 1.9* This game works your mind AND is lots of FUN! Some of my favorite things about this app are the little dots that you can put in the boxes as a possibility if you’re not sure, that it automatically takes away the small dots when they are no longer possibilities, that if puts an X through the dot IF that color won’t work, and that there is an option to check your work for errors. ### 5/5 — Color Sudoku *2023-06-06, version 1.7* Boy Howdy has great games! Color Sudoku is a pretty and fun sudoku game. Their other sudoku games are great, too! I play them Often! ### 5/5 — I Love This App! *2023-02-18, version 1.7* I like that you can place little markers for possibles. It’s a great puzzle to do by myself or my grandkids. ### 5/5 — Different take on Sudoku. 👍🏻😃 *2022-10-08, version 1.6* I normally freak out with sudoku, numbers are not my thing.😱 However, I really like this colour sudoku it’s really cool and thought I’d download it and I’m glad I did. Challenging levels and great game. Helps my blonde brain too!! 😀 ### 5/5 — ColorSudoku *2021-10-28, version 1.6* Best game ever for all ages! ### 5/5 — Love your games *2020-10-19, version 1.5* Boy Howdy as some of the best, consistent and fun games around.
