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.

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.

Nice little game if you like Suguru. No video ads only a small banner. Thanks. I've had a Suguru book before where you can find a way to determine every block, one after the other. Here sometimes the only way to fill up the square is to get a random missing number and go with that, than if it will be wrong later, go back and try a different number. Still very strategic and fun. 4*

V good version of suguru, with a tonne of puzzles at all difficulty levels. Using it could be smoother though — there's no way to check if your answers are right short of finishing the puzzle, and although you can write in numbers as tentative options, there's no way to write *just* a 1 in the corner of a cell, only two or more numbers. If you're looking for a minimalistic, 100% free version of suguru with near-infinite puzzles, this is the game for you.
