Switching between numbers and colors feels like switching brain modes. It’s playful, dynamic, and somehow effortless. I never thought Sudoku could feel this fresh, especially with the hidden historical twist on the diagonal. Totally hooked.

The mix of numbers and colors is already fun, but what really surprised me was the opening riddle. Solving it and then spotting the date inside the grid felt like uncovering a secret. It’s Sudoku, but with a story.

What a surprise! I came for the Sudoku challenge, I stayed for everything else. The avatars evolving with your progress made me smile, and the difficulty curve is so well designed—I always feel just smart enough to push to the next level. And finding the hidden historical date in the diagonal? That was the cherry on top.

At first I thought: “Too complicated, I’ll never get it.” Five minutes later, I couldn’t put it down. The mix of logic and colors is surprisingly natural, and when you hit the riddle that hides a date, it feels like you’ve uncovered a secret message. Addictive!

Hello, I’ve done the grid. I hope it was right. It was fun to fill in both the numbers and the colours ! It adds an extra difficulty but I really liked it ! I don’t know how to save or send my grid so I just took a screenshot for you. Have a nice day.

SUDOKING is exactly the kind of upgrade Sudoku needed. Smarter, deeper, more playful. The 20 avatars give it charm, the 7 difficulty levels give it structure, and the hidden date riddles give it culture. It’s rare to find a game that mixes intellect and imagination this well. I’d happily pay double the subscription price.

Finally, a Sudoku with personality! I picked a female avatar, and watching her evolve step by step through the 7 levels made the whole experience feel like a journey. The colors and numbers force me to think in new ways, and the hidden date riddle gave me goosebumps when I solved it.

Classic Sudoku never hooked me. But SUDOKING? Totally different. The double grid (numbers + colors) makes every move meaningful, and the “only one number–color pair per grid” rule keeps the tension high. Add the avatars leveling up to royalty and a hidden historical message… this isn’t a puzzle, it’s a world.

Girish Sharma

For me, this is Sudoku leveled up. More strategy, more surprise, more satisfaction. The fact that each grid hides a historical reference makes me feel like I’m learning something while playing. I already do several a week… now it might become daily.
