About this game

Suguru, also known as Tectonics or Number Blocks, was invented in Japan. These puzzles have very simple instructions, but a very wide range of difficulties, from easy to insanely complex.

Suguru is a great logic puzzle with two very simple rules. The cells in each puzzle grid are divided into groups, and each group contains the numbers from 1 to N, where N is the number of cells in the group. Thus, a group containing 5 cells will contain numbers from 1 to 5. The second rule is that no two adjacent cells, including diagonal, can contain the same number. Despite these two rules, some puzzles can be incredibly difficult to solve.

Don’t be fooled by the size of the grid, and Suguru’s apparent simplicity. This is a puzzle that can, at its most difficult, challenge the most experienced of solvers. Be warned, this is an addictive puzzle like no other, and a uniquely satisfying one.

In our application, we have created 6000 unique levels with varying degrees of difficulty. If you are playing Suguru for the first time, try the level “Novice”. Each difficulty level contains 1000 unique levels. Where level 1 is easiest and 1000 is the most difficult. If you can easily solve the 1000st level of one difficulty level, try the first level of the next level of difficulty.

Sep 25 Still great game. Can I pay & remove ads? I don't want all the games in a bundle right now. (Oct 2023: Great app! Thank you 😊 I'm enjoying the game and it's well set out and easy to access different levels. The placeholder mini numbers is very helpful. Could be quite nice to ✔️1} go almost straight to the next board when you complete one. Not tapping back to the Level selection but say have an Arrow to Start Next Board. 2} A different colour background option like blue?? 💙)

Yep, I like this app. Keep coming back to this, and their Futoshiki app for ease of use. Wonderful not to have to press a seperate icon to adding the smaller 'penciled in' numbers, you just add more numbers into the square and it turns the large single number into smaller numbers. Then when you remove all but one of the smaller numbers it turns the remaining one into a large number. So simple to use.

Fun game to figure out at first, except I had issues with puzzles like levels 2 and 3 of casual (I'm not sure if they're the same across all devices) but the puzzles were impossible. For example I'd have an unsolved group of 3 cells, that can have any number of 1, 2, or 3, with the only issue being, all 3 cells were adjacent and or diagonal too a 3, so although 3 is supposed to go in one of those cells, it is impossible, when testing it by putting 3 in each square all 3 said it was wrong.

If you think some level is impossible to solve, please contact me via support email with difficulty and level number, and I will send you solution for the level. BTW, all levels are solvable and have unique solution.
