2 NANRO 80 POINTS Place numbers into some of the cells so that no x area is completely covered by numbers. All numbers in a region must equal to the number of numbers in that region. If two edge-adjacent cells are in different regions, they cannot contain the same number. Finally, the set of all cells containing numbers must occupy a single connected area TURNING FENCES 95 POINTS Draw a single closed loop by connecting dots horizontally and vertically. The numbers in the grid indicate the amount of turns taken on the four dots around it TOROIDAL SYSCRAPERS POINTS Enter a digit from 1 to 5 (1 to 4 in the example) into each white cell so that each row and column contains each number exactly once. Each digit in the grid represents the height of a building. Clues with arrows inside the grid indicate how many buildings can be "seen" when looking from that direction. The grid is considered to be toroidal, i.e. the rows and columns are wrapped around and visibility is assumed. Taller buildings block smaller ones from being seen

3 I I TENTS POINTS I I I Place a tent horizontally or vertically next to each tree. Tents do not touch each other, not even diagonally. I I I ARAF 0 POINTS Divide the grid into connected regions so that each of these regions contains exactly two numbers. The area of a region should be strictly between the two values given by the two numbers in that region RENBAN-FRAME SUDOU 85 POINTS Place digits from 1~9 in each blank cell so that every row, every column, and every outlined region has distinct digits. The shaded groups contain a set of consecutive digits. The number outside gives the sum of the first digits in that direction FILLOMINO POINTS Divide the grid into different regions along the gridlines. No two regions of the same size can touch each other by a side. Numbers in the grid indicate that this cell is part of a region of that size. A region can contain more than one given number. There can be regions without any given numbers

4 TRUE-FALSE SNAE 50 POINTS 5 5 Find a snake in the grid whose head and tail are given but its length is unknown. The snake cannot touch itself, not even diagonally. Numbers indicate the number of cells occupied by the snake that are pointed at by their arrow. The snake is allowed to occupy cells with clues. Clues that are occupied by the snake are all false, while the other clues are all true STAR BATTLE 40 POINTS Place the given number of stars in each row, column and thick bordered region so that stars do not touch each other, even diagonally. TAPA POINTS Shade in blank cells to form a single contiguous wall. There can be no x group of shaded cells. The clues indicate the length of shaded cell groups in the 8 cells around the clue cell. If there's more than one digit in the cell, the shaded groups have to be separated by at least one white cell. A? can stand for any number from 1-8. It is upto the solver to determine the value. 1 4?? 1 1 4?? 1

5 MASYU 0 POINTS Draw a single closed loop connecting the centers of cells horizontally and vertically. The loop doesn't touch or cross itself anywhere. The loop runs through all black and white circles. The loop turns in every black circle and goes straight through both adjacent squares. The loop goes straight through every white circle and turns in at least one of both adjacent squares. EASY AS ABC UNTOUCH POINTS A B C A B A B C A B A B C Place a letter from the given range (A~C in the example) in each cell, so that each letter occurs exactly once, in all rows and columns. Some cells will remain empty in each row and column. The letter outside the grid is the first letter seen from that direction. Same letters cannot touch even diagonally. B C A B A B C B C A A B C B UROTTO POINTS Shade some cells to form regions. The number in a circle gives the sum of the number of cells covered by the regions that are connected to it orthogonally. Regions may touch each other only diagonally. Cells with circles cannot be shaded and empty circles may have any number of shaded regions connected to them

6 SYSCRAPER PENTOMINO 80 POINTS 1 1 Place all 1 pentominos into the grid, they can be rotated and/or reflected but they cannot touch each other, not even diagonally. No pentomino can be placed onto black cells. For any row/column, a contiguous segment of N cells containing pentomino parts is considered to be a building of height N. Numbers outside the grid indicate the number of segments that are visible from that direction given that height definition. Buildings (segments) of length N block visibility of all other buildings (segments) of length N or below that are behind them. WORD NURIABE 40 POINTS Place the given words into the grid so that they are readable in horizontally and vertically consecutive cells. Different words do not touch each other by side but they can touch diagonally. The remaining cells form a single connected shape that cannot have any x area anywhere. One letter from each word is given. P Z W Word Puzzles Example P L W O R M E D A Z Z X U L E E P S 4 4 SNAE 5 POINTS Locate a snake in the grid, whose head and tail are given. The snake does not touch itself even at a point. Numbers outside the grid indicate lengths of snake segments in the corresponding direction.

7 CAVE 50 POINTS Draw a closed loop over the grid lines. The loop goes around all numbers. The numbers in the grid indicate how many cells inside the loop can be seen horizontally and vertically from that cell, including the cell itself SHAASHAA 90 POINTS Colour triangles in some squares so that the remaining white spaces are all shaped like rectangles. The triangles have to split a square into two equal size right angled triangles. The numbers in the black squares indicate how many of the four adjacent squares are to be coloured with a triangle
