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.

Okay, so I've been click baited several times, but this game is truth. Game plays as the ad shows. Really makes you think. Ponder a moment. Initially the game walks you through a guide on how to play. After that, you are on your own, but it is easy enough to understand. Then it throws a twist. Great game, love it. Well done.

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?

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.

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.
