Simply SUDOKU....

I love to solve Sudoku, whenever and wherever I get to solve it. I always try to beat my own time limit. After solving the Classic types for around 10 years now, I moved on to solve different types of Sudoku giving a taste of different food to the brain. Here's a list of SUDOKUs I have solved so far. But I am still naive in this brain game. Try out some of these in your free time.

Jigsaw Sudoku: Fill the grid with the given jigsaw pieces. The grey cells already labeled in the grid cannot be moved. Jigsaw pieces cannot overlap with each other or the grey cells in the grid, and have to cover all white spaces in the grid. Then fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9.Jigsaw pieces can be rotated with the digits and their positions fixed, but cannot be turned over.

Dots- Kropki Sudoku:Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9. If there is a black dot between two neighboring cells, one of the digits is twice as large as the other. If there is a white dot between two neighboring cells, one of the digits is larger than the other by 1. Note that not all feasible pairs are labeled. Between the digits 1 and 2 there can be either a white or a black dot

Dots – Kropki calculative Sudoku:Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9. If there is a black dot between two neighboring cells, then the sum/product/difference/quotient of the two digits equals 10. If there is a white dot between two neighboring cells, then the sum/product/difference/quotient of the two digits equals 5. Note that not all feasible pairs are labeled.

Little Killer Sudoku: Fill in the grid so that every row, column and 3x3 box contains the digits 1 through 9. Numbers with arrows indicate the sum of the numbers along the diagonal in that direction.

Diagonal Skyscraper Sudoku: Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9. Digits on the exterior specify the number of digits visible in one of the two diagonal directions. The order of the two digits is not necessarily consistent with the order of the arrows. The digits on the four corners specify the number of digits visible along the four main diagonals. A digit blocks the view of any other smaller or equal digits.

Diagonal Consecutive Sudoku: Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9. All diagonally adjacent cells that differ by 1 have been connected by a slash.

Windmill Sudoku: Fill in the grid so that every row, column, and 3x3 box contains the digits 1 through 9. All cells connected by each grey broken line also contain digits 1 through 9.

Every puzzle has an answer, no matter how much time is takes to arrive at the solution. Same it is for the life journey.
