Place a mine in some of the empty cells. A number in a cell indicates the number of mines in adjacent cells (including diagonals).
The rules were taken from here.
Insert a digit from 1 to N into each cell in the N by N grid so that no digit repeats in any row or column. Also, the number in the upper-left corner of a bold cage indicates the value of a mathematical operation (addition, subtraction, multiplication, division) applied successively to all digits in the cage, starting with the largest digit for subtraction and division (e.g. 1,2,4 with subtraction is a 1- clue as 4-2-1 = 1). The operation may or may not be given in the cage, but at least one of the four operations must apply. Digits can repeat within a cage.
The puzzle has a single solution.
Fill in the grid, so that each row and each column contain all of the numbers from 1 to 6. The numbers inside the grid represent skyscrapers of those heights. A number next to a row or column, indicates how many skyscrapers from that row or column can be seen from that position. Taller skyscrapers block the view of shorter skyscrapers that are located anywhere behind them. There is a unique solution to the puzzle.

Fill in the grid, so that each row and each column contain all of the numbers from 1 to 5. The numbers inside the grid represent skyscrapers of those heights. A number next to a row or column, indicates how many skyscrapers from that row or column can be seen from that position. Taller skyscrapers block the view of shorter skyscrapers that are located anywhere behind them. There is a unique solution to the puzzle.

Draw horizontal and vertical lines, starting in the cells with numbers, so that each empty cell (without a number in it) is used by exactly one line. Aside from their starting cells, lines cannot enter cells with numbers. Each number indicates how many cells are covered by lines starting in this cell, not counting the number cell itself. The puzzle has a single solution.

ציירו קווים אנכיים ואופקיים, שמתחילים במשבצות עם המספרים, כך שבכל תא ריק (ללא מספר) יעבור בדיוק קו אחד. קו לא יכול לעבור במשבצות שיש בהן מספרים, מלבד המשבצת שממנה התחיל. משבצת עם מספר מציינת כמה משבצות ריקות מכילות קו שיוצא ממנה, לא כולל את המשבצת הממוספרת עצמה. לחידה יש פתרון יחיד.

Rules:
Place the given shapes into the grid, so that they do not touch each other, not even diagonally. Shapes can be rotated and reflected. Each shape must be used exactly once. Each shape must lie completely in an outlined region, and each region must contain exactly one shape. (The shapes in the puzzle are the full set of twelve pentominoes.)
חוקים:
מקמו את הצורות בטבלה כך שהן לא תיגענה אחת בשנייה, גם לא באלכסון. ניתן לסובב ולשקף צורות. כל צורה צריכה להופיע בטבלה בדיוק פעם אחת. כל צורה צריכה להיות מוכלת לחלוטין בתוך איזור תחום אחד, וכל איזור תחום צריך להכיל בדיוק צורה אחת. (הצורות בחידה הן הקבוצה של כל 12 הפנטומינו-ים.)
Connect horizontally and vertically adjacent dots so that the lines form a single closed loop. The loop may not intersect with itself. Some of the squares have a number in them, representing how many of that square's four edges have a line drawn through them. The puzzle has a unique solution.
In the following puzzle, none of the numbers are correct. Each number is either higher by exactly one or lower by exactly one than the correct hint that should be written in its place (some numbers are higher, and others are lower).
חברו נקודות שכנות על ידי קווים אנכיים ואופקיים, כך שהקווים ייצרו לולאה סגורה אחת. הלולאה לא יכולה להצטלב עם עצמה. בחלק מהריבועים כתוב מספר שמציין דרך כמה צלעות של הריבוע עוברים קווים. יש לחידה פתרון יחיד.
בחידה הבאה, אף אחד מהמספרים לא נכון. כל מספר יהיה גדול בבדיוק 1 או קטן בבדיוק 1 מהרמז שאמור להיות במקומו (חלק מהמספרים גדולים יותר וחלק קטנים יותר).
