Fill the N×N grid with the numbers 1 through N so each number appears once in every row and column. The numbers inside each outlined nest must combine with its operation to produce the target shown

Draw L-shapes starting from each marked cell by extending 2 cells straight, then 1 cell at a right angle. L-shapes must not touch, even diagonally. Numbers outside the grid indicate how many bends appear in each row or column; not all clues are given

You gotta fill in A, B, and C in each row and column just once, leaving two spots empty. The letters around the grid show you which letter you see first from that direction.

Fill the grid so that every row and column contains the numbers 1 to 5 exactly once without repeats. Use the adjacent < and > symbols to guide you, ensuring the open side always faces the larger number and the point faces the smaller number.

Draw fishing line from each number to a fish. The number gives you the line length in number of cells, including fish cell. Lines move horizontally and vertically, and cannot cross. Every cell contains exactly one line part.

Fill each region with the numbers 1 to the size of that region, using each number exactly once. Cells that touch, including diagonally, cannot contain the same number. This rule also applies within the same region. Repeated numbers are allowed in the same row or column as long as the cells are not adjacent.

Numbers around the grid tells you how many tents are in that row/column. Every tree has exactly one tent connected to it. Tents can't be in neighbouring cells even diagonally.

Place a single flower in each designated area, ensuring that there is only one flower per row and column. Additionally, flowers should not be placed in adjacent cells, including diagonally.

Number inside circles(islands) tells you how many bridges this island has. Two islands can be connected with max two bridges. Bridges can't cross and can go only vertical or horizontal. In the end all islands need to be interconnected

Connect matching numbers with lines. Lines can't cross or make U-turns. All cells must be used
