This is one of the puzzles I sent to superrabbit for last year's Secret Santa.
A larger 20x20 version can be found here.
If you like pencil puzzle hybrid puzzles, give it a go! :)

RULES:
Draw a non-branching, non-overlapping loop along the edges of the cells. In each quadrant of the grid, the clues of two different genres need to be satisfied.

Line of Sight (left column): Clues represent the length of the first straight line segment seen in the indicated direction. A questionmark marks any length larger than 0.

Slitherlink (right column): Clues represent the number of edges drawn surrounding the clue.

Masyu (top row): The loop must pass through every circle. The loop must turn on black circles and travel straight through the next vertex on either side. The loop must go straight through white circles and turn at at least one of the vertices on either side.

Tapa-like Loop (bottom row): Clues represent the numbers of consecutive vertices occupied by the loop each time it enters the (up to) eight vertices surrounding the clue. The loop may not pass through a clue. Questionmarks mark any length.


Below is a 6x6 example, which is also a nice puzzle.
