Suguru

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.

Futoshiki

What is Futoshiki?

Futoshiki is a funny logic puzzle game from Japan. In this game you need to fill all cells with numbers. Some cells can be filled initially, the rest is filled by the player. The game is very similar to the game 'Sudoku', but it has a difference. On the playing field, in addition to numbers, there may also be signs (more, less). The sign between two cells means that one number is greater than the other.A correctly filled square must satisfy the following three conditions:
1. The numbers in each line should not be repeated.
2. The numbers in each column should not be repeated.
3. If there are signs (arrows) on the field, then the condition must be met. (One number is smaller than the other).

Levels.

In the program you can choose 6 difficulty levels (4x4, 5x5, 6x6, 7x7, 8x8 and 9x9). The larger the square, the more difficult it is to go through. If you play Futoshiki for the first time, we recommend that you start with a 4x4 square. At each level of complexity you will be offered 2000 unique game levels. The higher the number the more difficult. (Level 2000 is the most complex).
How to play?

To change the value of a cell - first select it, and then click on the numbers at the bottom of the screen to put a number in the cell. You can put several numbers in one cell at once, but the level is considered passed, when in each cell there is only one number. If you want to remove a number from the cell, select it and click the corresponding number in the bottom of the screen.

Hexoku

Your goal is to fill all hexagons with numbers from 1 to 6. Some numbers are already filled. There are only two simple rules in the game:

• There can be only unique numbers in each hexagon (1, 2, 3, 4, 5, 6). Therefore, there cannot be two identical numbers in one hexagon.
• Two adjacent cells from different hexagons must have the same number.

That sounds easy, right? However, passing some levels can take a lot of time and effort.

We have created 3000 unique levels with varying degrees of difficulty in our application. If you are playing Hexoku for the first time, try the level “Novice”. Each difficulty level contains 500 unique levels. Where level 1 is the easiest and 500 is the most difficult. If you can easily solve the 500st level of one difficulty level, try the first level of the next level of difficulty.

Good luck!
