**Rules for Tapa**

**Play this puzzle on PUZ-PRE**

Enter numbers from 1 to 5 (from 1 to 6 in second puzzle) into white cells, so that no number appears more than once in every row or column. Number represents the height of skyscraper in the cell.

Number with arrow indicate how many skyscrapers are visible from that direction.

In this puzzle, the grid is toroidal.

Place the given fleet in the grid.

Numbers in the grid indicate the total amount of cells occupied by ship segments in that row and column.

Ships can't be placed on cells with numbers.

Place digits from 1 to 5 in some cells, so that no digit repeats in any row or column.

The numbers abobe the grid indicate the sums of consecutive digits in the correct order.

Shade in some cells. Shaded cells are not allowed to be orthogonally adjacent.

Draw a closed loop that passes through all the remaining cells.

A number in a region indicate the number of shaded cells in that region.

Some segments of the loop may be given.

LMI Sudoku test "Classics vs. Innovatives"

**Rule:**

Apply classic Sudoku rules.

Numbers on the top show the digits sandwiched by even numbers(i.e. digits whose vertically adjacent cells are both even) in the corresponding column in any order.

Numbers on the left show the digits sandwiched by even numbers in the corresponding row in any order.

All possible numbers are given. In partucular,no digits are sandwiched by even numbers in clueless rows/columns.

LMI test "Logirace"

**Rules:**

Draw a single closed loop passing through some cells in the grid.

This loop is snake-like, that means the loop cannot touch itself, not even diagonally.

Every 3rd square of the loop has a dot on it.

Numbers outside the grid reveal how many dots of the loop are in the corresponding row or column.

The squares marked X are not part of the snake.

LMI test "Logirace"

**Rules:**

Draw a single closed loop passing through all cells in the grid.

The loop cannot touch or cross itself.

It makes turn at black circle and goes straight at every white circle.

There are no loop segments on cells marked X.

Enter the digits from 1 to 3 into the diagram, so that every digit appears exactly twice in every row and every column.

The numbers are replaced with letters.

The same letters are the same digits and different letters are different digits.

The content of overlapped parts is common for both grids.

Rules are satisfied for each grid independently.

Place the given fleet into the grid.

Ships cannot touch each other even diagonally.

Digits outside show the number of cells occupied by the ships in the correspnding row or column.

Make some figures by drawing lines so that each figure goes through just one clue.

All the cells will be visited by lines.

Each clue shows how the lines of the figure upon it turns or connects without any rotation or reflection.

(The clues do NOT inply lengths of any part of the line)

Different figures do not share same cell.

No Numbers Loop was invented by Xevs.

**Rules:**

Draw a closed loop in the grid.

The loop can cross itself but otherwise never visits any point twice.

In any of two adjacent squares, the line segment can't form a number in any orientation. (listed below).

Numbers outside the grid shows how many clossings exist along the direction.

Some parts of the loop are already drawn for you, and the loop can't go through a segments with "X".
