Location: India | Sorry guys for delaying things a bit too much. Got extra busy with work. Anyways Mock Test 15 puzzles are almost ready with the following list:
Will upload a proper Instruction Booklet tomorrow. In case of any confusion please post your queries here.
1] Mirror Sudoku:
R(m)C(n) = R(9-m)C(9-n) for all 4 corner boxes. In short box 1&9 and box 3&7 will have digits so that they form mirror image. (eg: R3C2 & R6C7 will have same digits)
2] Repeatable Extra Region:
There are two extra regions of 9 cells each but digits can repeat in those regions. Both the regions contains same set of numbers, same number of times.
eg: If one region contains 1,1,2,3,4,4,5,7,9 then the other region will also contain same numbers 1,1,2,3,4,4,5,7,9
3] Circles
There are several circles in the grid each passing through 4 cells. There are 4 digits entered on the circumference of each circle. These 4 digits should occur in the same 4 cells in the same order (meaning the circle can only be rotated).
It will be more clear once you see the example in the IB.
4] Knight Moves:
All same digits with knight step away are marked in the grid.
5] Diagonally Consecutive:
All diagonally adjacent cells which are consecutive are marked with a line.
6] Wrong Sky skyscraper:
Skyscraper rules apply. The digits outside the grid are +1 or -1 than the skyscrapers observed for that row or column.
7] Quad Max/Min:
http://www.sachsentext.de/en/maxquad1.htm
sudoku is similar to above variant but the dots will mean that the cell is either smallest or the largest amongst the 4 cells.
8] Equation Sudoku:
There are 9 alphabets in the grid, each representing one number. There are numbers given outside the grid which are sum of the digits of all alphabets in that row/column
9] BlackOut Sudoku:
My all time favourite. Each row/column/3x3 region contains one cell which is blacked out. Fill the grid such that no numbers repeat itself in 3x3 region/row/column. Check ISC2009 or fed-sudoku online variants for more.
10] ArrowPath Sudoku:
In a 3x3 box there are arrows in each cells. The arrows are such that 1 points to 2, 2 points to 3.... 8 points to 9 and 9 points back to 1 (in 3x3 box only)
11] Palindrome Sudoku:
ISC2010
12] There are 2 digits outside each row and column from both sides. (If 6,4 are outside digits to the left of row 3 then either R3C4=6 or R3C6=4.)
In case of any confusion please feel free to ask as the IB will take another day.
Also there might be a possiblity that 1 or 2 puzzles from above list might be replaced.
Cheers

Havn't understood "Descriptive Pair Sudoku", could someone please explain?
In the example, look at Row1. The left side hint is 26. That means In Row1, either 2 is at 6th position OR 6 is at 2nd position
i.e. either R1C6 is 2 OR R1C2 is 6
Is it clear now?

Sorry for an error in the instructions of mirror sudoku.
Correct instruction is R(m)C(n)=R(10-m)C(10-n)
I hope you will enjoy the puzzles. |
