The new color themes make it even more fun!! ### 1/5 — Update wrecked a fun game *2026-06-18* The update is terrible. Colors are pale and hard to distinguish one from another. No longer marks completed cell, rows and columns. And I can’t even play it on my iPad because it doesn’t fit on the screen. Go back to the way it was. I dpm’t care about having multiple players. ### 5/5 — Must Try Game *2026-03-29* I love this game it’s honestly so fun, low pressure, and relaxing. It’s fun to try doing sudoku without looking at numbers and being able to see how good I am at pattern recognition. It’s better than a lot of other popular games out there and I can play whenever, and test my skills with different levels. It’s very user friendly as well and I like the upbeat music and animation style. Definitely give this a try and pick it up again whenever you have time and it’s nice because you can always return to play it later! ### 5/5 — Great new game *2025-05-31* I found that Color Sudoku quickly became my go-to way to relax and clear my mind. I like to puzzle and this was a great new way to play. ### 5/5 — Highly Recommend! *2025-05-04* I really liked this new take on Sudoku! It’s a refreshing new way to play compared to the classic number-based puzzle, replacing digits with colors to challenge your pattern recognition instead of pure logic. The visuals are vibrant and make the experience feel more relaxed and artistic. It’s great for casual play, especially if you’re looking for a chill game to wind down with. Hardcore puzzle gamers will stay interested as the levels have varying difficulty. The controls are pretty smooth, and I really liked that the correct sequences are highlighted when correct! Overall, it’s a fun and creative spin on Sudoku that’s worth trying for a new kind of mental challenge. I’m definitely going to keep playing. ## Frequently asked questions about Sudoku ### What is Sudoku: Color?
