Just sharing some of my other puzzles. Let me know what you think.

Hidato

Had done a few of these puzzles, but never really found them challenging. Then found a bunch I did like, as they were a bit challenging. So I made one myself. Touch puzzle, but I really enjoy how it turned out logicwise.

Rules:
Draw a path of consecutive numbers in the grid from 1-81. The path can go horizontally, vertically and diagonally. There can only be one number per square. Some of the numbers have been given. Figure out the path.

Here's a second puzzle type. It's a mix between LITS and Sudoku.

LITSudoku Jigsaw

Place the digits 1-6 in each row, column and jigsaw piece.
This puzzle is also a LITS puzzle. In each Jigsaw piece, 4 connecting cells are to be coloured in the shape of a tetromino. All tetrominos are connected and will form one polyomino. Tetrominos of the same shape can't touch, rotations/reflections are considered the same shape. Nowhere will there be an area of 2x2 coloured cells.
Each tetromino will contain the digits 1-4.

LITSudoku

Place the digits 1-9 in each row, column and 3x3 area.
This puzzle is also a LITS puzzle. In each 3x3 area, 4 connecting cells are to be coloured in the shape of a tetromino. All tetrominos are connected and will form one polyomino. Tetrominos of the same shape can't touch, rotations/reflections are considered the same shape. Nowhere will there be an area of 2x2 coloured cells.
Each tetromino will only contain odd digits.
Grey coloured cells are part of a tetromino.

Okay, my LITS description is a bit awkward. It's like normal LITS.

Hope you enjoy them

Hah, I just did the LITSudoku Jigsaw and it was really weird having to go through all of these rules. I'm sure one can make really tough puzzles by combining genres but at one point it's probably just not fun anymore...

There aren't any different rules from normal LITS. Basically it's like odd/even sudoku except odd cells(1-4 for the Jigsaw) are defined by LITS pieces.

It's not really meant as a new genre, just a one time twist. Liked how it turned out myself.

I recently stumbled upon Gareth Moore's blog. I don't know if he's on here or not but he has some whacked out puzzles. I still haven't solved his toroidal numberlink (where lines can pass through the puzzle walls and come out from the other side).

Here's another one.

Killer Sudoku

You guys know the drill.

Rules: 1-9 in every row, column and marked 3x3 area. The numbers indicate the sums of the cells of each coloured cage. No repeats within each coloured cage.

Here's a new puzzle by me. I'm not sure if the combination of the 2 has ever been done before. I can't remember ever seeing it. If it has been done before, feel free to correct me.

Outside Skyscraper Sudoku

Fill the grid with the digits 1-9 so they appear once in every row column and marked 3 by 3 area. Outside the grid are pairs of clues. Of each pair one clue is an Outside Sudoku clue and one is a Skyscraper Sudoku clue. The Outside Sudoku clues indicate that the digit appears in one of the first 3 cells of that row or column from that side. The Skyscraper Sudoku clues indicate how many digits are visible from that side. Smaller digits hide behind larger digits.

Hope you enjoy it.

This time some puzzles types from the Fifth World Sudoku Championship

Dragon Sudoku

Fill the grid with the digits 1-9 so they appear once in every row column and marked 3 by 3 area. Each 9 "sees" exactly 8 other distinct numbers. They see in all four directions until they hit a wall.

http://www.worldpuzzle.org/wiki/index.php/Dragon_Sudoku

Hexagon Sudoku

Fill the grid with the digits 1-9 so they appear once in every row column and marked 3 by 3 area. Digits do not repeat along any of the three directions in which the hexagonal cells share edges.

http://www.worldpuzzle.org/wiki/index.php/Hexagon_Sudoku

Just One Cell Sudoku

This puzzle has multiple solutions for the entire grid, but there is at least one empty cell that will contain the same digit for all solutions. You are to locate and clearly identify just one digit that can be placed into the grid with absolute certainty. No digit may appear more than once in any row, column or marked 3 by 3 area.

Enjoy

Again three types that featured on the Fifth World Sudoku Championship

Sudo-Kurve

Place the digits 1-9 once in each of the five 3 by 3 boxes and 10 bent "rows" (indicated by light curved lines). All "rows" contain exactly 9 cells.

http://www.worldpuzzle.org/wiki/index.php/Sudo-Kurve

Deficit Sudoku

Place the numbers 1-9 in each row and column. Each number appears at most once in each region but might not appear in all regions.

http://www.worldpuzzle.org/wiki/index.php/Deficit_Sudoku

Arrow Sudoku

Place the numbers 1-9 in each row, column and marked 3 by 3 area. The digits in each circled cell must equal the sum of all the digits along the arrow's path; digits can repeat within an arrow.

http://www.worldpuzzle.org/wiki/index.php/Arrow_Sudoku

Never really hear much back about these puzzles, but I hope people actually solve and enjoy them.

Enjoy

Last three types that featured on the Fifth World Sudoku Championship

Outside sudoku

Place the digits 1-9 once in each row, column and marked 3 by 3 area. The clues outside the puzzle indicate this digit will appear in one of the first 3 cells in that row or column from that side.

http://www.worldpuzzle.org/wiki/index.php/Outside_Sudoku

S as in Sudoku

Place the numbers 1-9 in each row, column and marked 3 by 3 area. The letters in the grid can be any digit in which this letter appears in their given English spelling.

http://www.worldpuzzle.org/wiki/index.php/S_as_in_Sudoku

Tripple Quadruple Sudoku

Place the numbers 1-9 in each row, column and marked 3 by 3 area. This puzzle consist of 4 linked puzzles. Each puzzle has three shaded regions. Each region will exactly correspond with one of the three shaded regions in each of the other three puzzles.

http://www.worldpuzzle.org/wiki/index.php/File:Triplequadruple-example.png

For anyone who actually looks and solves these puzzles, enjoy

Okay, here is another simple variation on a variant. Again haven't seen this like this before. I have seen Frame sudokus where you get the sums of the first 3 digits from the outside in each row and column. Also have seen puzzles where they varied the amount of digits.

for this one I have changed it a little though. In this puzzle I won't tell you how many digits will add to the sum. That is for you to figure out. You'll just know that if you add the digits from that side, some amount will add to the given sum.

Because Frame Sudoku always mark till what point the digits add to the sum, I've called this type Frameless Sudoku as there is no frame marking the length of the sums.

Frameless Sudoku

Place the digits 1-9 once in every row, column and marked 3x3 area. The clues on the outside are the sums of the first digits you see from that side. The amount of digits is not set. It can be as low as 1 digit and as high as 9 digits. They can differ from sum to sum.

Hope the rules are clear to everyone. any questions about it, just let me know.

Anyways, enjoy this puzzle. I'm happy with how it turned out.

FrameLess Sudoku : The concept is very nice. The rules are simple, but the puzzle type is very interesting.

Thanks. At first I wasn't sure this would work, because the options for sums increase a lot. But once I got a solid opening built in, I noticed how much freedom you still had with the sums.

A little while back I designed a few of these again. I still like the idea. Haven't seen it used anywhere by anyone else.

Frameless Sudoku

Place the digits 1-6 once in every row, column and marked 2x3 area. The clues on the outside are the sums of the first digits you see from that side. The amount of digits is not set. It can be as low as 1 digit and as high as 9 digits. They can differ from sum to sum.

Even for it's small size, it's pretty interesting. I could have only given one sum for each row and column as they are all split up into 2 sums. But I don't really like to leave out clues that are technically given.

Worked in a whole different opening in this one. Might take a while to find.

Hope you enjoy hem, they're not the easiest, but still happy with how they turned out.
