In multi-sudoku, several ordinary 9x9 sudoku puzzles are combined into one, connecting with each other by a different number of common cells.
As a rule, it is impossible to solve each of the Sudokus separately.
Regular Sudokus are also published in the section
Left click/tap - iterate through numbers with preliminary focusing. Right click - reverse enumeration. You can make notes in each cell by inserting up to 20 numbers and other symbols.

The "/" (slash) key on the keyboard - puts possible candidates in an empty cell.
