Every day, I publish a new Sudoku that represents a significant historical event, a celebrity's birthday or anything else of interest that can be associated with the particular day. Did you miss a day? No worries. Here are the latest seven Sudokus of the Day. Want to solve even earlier ones? You can see ALL of them in play mode.
Tired of regular Sudokus? Variant Sudokus are Sudokus where one or more rules are added on top of the classic rule. This brings a lot of variety to the table. The easiest example for a Variant Sudoku would be a Diagonal Sudoku where the two diagonals are two additional regions, meaning they must contain the digits 1-9 exactly once.
Consecudoku is a fun Sudoku variant. In addition to the normal Sudoku rules, all cells that have a white dot between them must be consecutive (have a difference of 1). All cells without a white dot between them must NOT be consecutive.
Windoku is a Sudoku variant in which you have some extra (coloured) regions. Those additional regions must contain the digits 1-9 exactly once. The usual regions (rows, columns, boxed) are of course also still valid.
X-Sudoku (a.k.a. Diagonal Sudoku) is a Sudoku variant in which you there are two extra regions: the diagonals. Both diagonals' cells must contain the digits 1-9 exactly once.
Entropy Sudoku is a fun Sudoku variant where each 2x2 box in the finished grid must contain at least one low digit (1,2,3), one medium digit (4,5,6) and one high digit (7,8,9).
Do you need a Sudoku as a present for your significant other, your friends or maybe mother's day? Here are some Sudokus that they will probably enjoy! How do you choose the right Sudoku? Green is for beginners, yellow for intermediates, orange for regular Sudokus solvers and red is beyond what is encountered in magazines and Sudoku books.
