This weekend Logic Masters India will host my puzzle test called hybrids.

It consists of 24 puzzles. They come in sets of 4. Each set has 2 familiar or less familiar puzzle types and 2 hybrids, which combine ideas from both puzzles into one. There's both easy and hard puzzles in there, so something for everyone to enjoy. If you can spare 2 hours this weekend, please participate.

I had a look at the variations.Pentopia looks great! I am scared about sea battle though I have no idea how that can be solved.

I would appreciate if someone can provide a general approach to sea battle .This variant could involve various logic ways to solve. Interesting,but scary

I'm posting the leftovers here now. Most were rejected for being too difficult, others were just second options. Will be posting them per genre.

This corral was considered too hard after testing. It's not the easiest have to admit, but one of the first harder ones I tried to make.

Corral

Draw a loop around all the numbers in the grid. The loop runs over the gridlines. Each number represents the amount of cells that can be seen from that cell, NOT including the cell itself.

NOTE: Normal corral includes the cell itself.

Enjoy.

Here are the leftover Worm Sudokus. They are both 1-9. I tried to make them 1-9 but couldn't get the difficulty down far enough to put them in the test. So don't think of these 2 puzzles too lightly.

Worm Sudoku

Place the digits 1-9 once in each row and column. Also draw 9 worms size 9 in the grid. Worms consist of a path or horizontally and vertically adjacent cells from head to tail. All cells are used. Worms can touch themselves. The heads and tails are indicated by the given digits. Each worm contains the digits 1-9 exactly once.

These are all around the same difficulty as in the test. One of the smaller puzzles actually has all the same clues. I thought it was a nice one, but preferred having something that actually required the logic deductions from the clue matching in the puzzles.

Outside Skyscraper Sudoku

Enter each digit from 1-9 in each row, column and marked 3x3 area. The pairs outside consist of one outside sudoku and one skyscraper clue, for you to determine which is which. An outside sudoku clue indicates that that clue appears in the first 3x3 area from that side. Each skyscraper clue indicates how many skyscrapers are visible from that side.

Here's some more Sea Battles for the ones who liked these. The 2 small ones are the harder than the one on the test. Especially the second one is relatively tricky for its size. The big one is a bit more complicated than the actual test puzzle.

Sea Battle

Place the given fleet in the grid so that in every row, column and boldly marked area exactly 2 ships appear. Ships don't touch each other, not even diagonally. Ships may cross over bold lines.

Sorry that the one picture might be a bit big. I can make a smaller one if someone would like it.

Here's 2 more pentopia puzzles. The big one was my bigger test puzzle to see how the puzzles turn out. It was also the reason I went for an unknown number of pentas because the puzzle was really nice but not all pieces were used. So then i tested it on a smaller size and that worked too, so I knew I had a nice puzzle type.

Pentopia

Place a number of different pentas in the grid; not all of them have to be placed. The pieces can't touch, not even diagonally. The pieces may be rotated and/or reflected. The lines in the grid indicate in what direction(s) the closest pentas are when looking from that square. Squares with lines can't contain pentas.
