About game
The application features 2,500 levels of varying difficulty. It includes both classic Sudoku and a multitude of multi-Sudoku variations, such as Samurai Sudoku, Triplets, Sohei, Butterfly, Tudoku, and others. Multi-Sudoku is a puzzle composed of several interconnected classic Sudoku grids, sharing common cells. Typically, on the intermediate and advanced levels, it is not possible to solve the individual component Sudokus separately; you must solve the entire puzzle as a whole. By revealing numbers in one Sudoku, new possibilities for eliminating candidates in others emerge.
How to play
Each individual 9x9 Sudoku grid must satisfy the condition of uniqueness for digits - in columns, rows, and each of the 3x3 squares, every digit should appear only once. Some numbers are already pre-set. You need to fill in the missing digits using logic.
In the cells, you can place and remove candidate numbers that you have identified as valid for that cell. According to the rules, invalid candidates are automatically removed.
On touchscreen devices, you can use your fingers to place digits and adjust the field size. On desktop, you can zoom using the scroll, place digits with the mouse, or use the keyboard. There are numerous settings that allow you to customize the gaming process according to your preferences. For example, you can customize the background, highlighting, enable automatic candidate calculation, adjust the behavior of the virtual keyboard, and much more.
