But very few of us have the opportunity to deal with gradations of color — a sense of order that works a different part of our brain. be well-rounded and balanced. enjoy beauty and not just black and white. go for Blendoku! ### 5/5 — Wonderful game! *2022-03-08, version 1.8.3* I love games like solitaire, logic games, crossword puzzles, etc. But Blenduko is the best game I’ve ever played. I have a disease that never lets me forget it. But when I play this game I forget everything that’s wrong with me. I can’t thank you enough for making this game. THANK YOU, THANK YOU, THANK YOU! ### 5/5 — Reddit Led Me Here *2022-01-08, version 1.8.3* A random Reddit comment mentioned Blendoku in passing, and I was curious, so I gave it a try! This is far more engaging than I thought it was going to be. I’m glad I found it. So far, there aren’t even many ads— I’ve encountered one in the past like 75 levels? Good stuff! ### 5/5 — Hey, I’m an impressed Artist! *2021-05-28, version 1.8.3* I love this game! I’m an artist. And this game tickles me right in my creative bits. Color theory for fun! Also, the app stopped working. I posted a review about it and no less then four hours later... it was fixed. So I’m revising my rating. Nice work devs. 5 stars for you. ### 5/5 — Yes yes yes *2021-05-11, version 1.8.3* Love it love it love it! Easy to use and makes you really think about color theory. The color blind mode is a really helpful feature even if you are not color blind; just flips it to different hues and makes you think differently. Nice time passer. ### 5/5 — Perfect! *2021-03-25, version 1.8.3* This game is the best! I went around the house trying to get my dads phone so I could play it until he let me download it on my iPad. I honestly have nothing bad to say about this game. Thank you for…making this game…exist. ### 4/5 — Fun and challenging *2019-05-09, version 1.8.3* I just downloaded this app yesterday and it’s pretty fun! My only complaint so far is that you only get 1 help every 12-24 hours (I forgot the specific time) If I cant figure out a level and already used a help, I have to wait at least half the day to solve that puzzle. The app does allow you to skip and come back later though, which is nice since it means I can continue playing. I also enjoy the colors that appear on the level select menu from a sensory perspective. ### 5/5 — Colorblind mode seems to work *2019-03-11, version 1.8.3* I love this game, but I figured my colorblind son wouldn't even be able to play. But wait, there's "colorblind mode" in the settings! Even though it looked the same to me, my son was able to play. Areas where I thought he'd have trouble, he did (choosing mid hues between orange fading to green and green fading to a reddish-purple), but not more than I'd expect a full color vision person to have. Good job! ### 5/5 — Blendoku *2018-06-19, version 1.8.3* I love all colors and I challenging games / so I thought I'd give your game a chance. It's interesting, at times I don't understand the order of the colors but all in all, I like the game. It's challenging in its own and I like it! Blendoku is quite different than most of these other games. Keeps you thinking and using your awareness and keenness to the various colors. I have the 2nd version and look very much forward to playing it as well. Now, if there was a way to draw and/or make shapes with all your colors - it'd be awesome!! Thanks!! ### 5/5 — Blendoku *2018-01-09, version 1.8.3* I find this game challenging, stimulating, and addictive! One puzzle may simply require going from dark to a light using one color much like a painter would add white to red which creates pink in lighter and lighter shades, while the next puzzle involves a more complicated split of two different colors that when blended would create yet another color in varying shades/hues.
