★★★★★ Robin Rolt · Jun 27, 2026

Fun and challenging logic puzzle. No timer, no "wrong guess" limitation, easy to restart a level if you get stuck, reasonable ad level. This one is a keeper.

★★★★★ Marianne Heynsdyk · Jun 18, 2026

Love this puzzle game, it's really satisfying to. Solve a grid l. it's a perfect balance of difficulty sometimes you have to think but not to a point it becomes frustrating. I love there's a zen mode as well. This game deserves more love and regonition, it's beautiful made and the puzzles are really fun and relaxing to solve.

★★★★★ Selah Solis · Sep 3, 2026

One of the best puzzle games I've ever played. Addictive. I love Shikoku with all my heart. One of my newer interests that I now get to share with all my friends. I downloaded it about a week or two ago, and I'm already past level 160. Simple, neat, and just the right amount of color. My love for strategy games has blossomed thanks to games like Shikoku, and Sudoku. If you like this game, you should also check out other games like Ken Ken, Kakuro, and Futoshiki. I play this when I can't sleep. ❤️

★★☆☆☆ Michael G · Aug 2, 2026

So there are "?" tiles that can represent any number. For many levels, these still end up being constrained, leading to one valid solution, which is great. But then there were levels with multiple potential valid solutions. It required guess-and-check to find the one solution the game was looking for. Then, I ran into level 104, which is *awful*. It has so many possible valid solutions that even guess-and-check is unrealistic. A logic game without a single logical solution is poorly designed.

This is a copy of another game called Almanac, this game was made 3 days ago, Almanac was released NOVEMBER 2025, The style, the gameplay, EVEN THE STREAK DESIGN is the same. CAN THIS GAME EVEN BE ORIGINAL?

★★☆☆☆ Smilley85 · Jun 22, 2026

While the game functionally runs, it expects you to solve it in just the way it "deems correct". If there are multiple ways to complete a level, it won't proceed until you found the intended one. On the other hand, you can cheese levels with locked numbers, as the locks will only spring if you selected the "correct" solution. One minor bug: locks become invisible if you restart a level after unlocking them. Other than that, it's just your run-of-the-mill clone puzzler you expect it to be.
