WPC10 Sample Puzzles 

Star Tours

Spaceships travel among the stars (large circles with letters) and space stations (small circles) along on the lines shown. The distance between selected pairs of stars is shown below. Determine the name of each star.

Botein - Deneb  9 Vega - Meres  5 Furud - Rigel  4 Toliman - Botein  8 Atlas - Subra  11 Coxa - Polaris  6 Kuma - Atlas  4 Furud - Coxa 12 Polaris - Vega  5

The Star

Fill in the empty cells so that each of the given words appears in the star diagram. Words can appear in any of six directions. A theme answer will appear in the two framed regions; also a related word is hidden symmetrically in the diagram.

Spaceship

One of the three spaceships is the original plan; the other two are both poor copies, each differing from the original in exactly ten details. Which drawing is the original?

Asteroids

Place the ten asteroid names into the diagram. The numbers on the connecting lines indicate how many letters the two connected asteroids have in common. Letters that appear more than once in a name count individually as independent symbols; for example, CELUTA had GALENE have three letters in common, not four.

ALTONA CELUTA DENISE EUDORA GALENE KYPRIA MELETE SEMELE VIRTUS ZELIMA

Four Marksmen

Four Marksmen had a shooting competition with three shots per person. Each of the 12 shots fired scored a different number of points (from 1 to 13), and at the end of the competition all four marksmen had the same total score. The diagram shows the situation after the first three shots. What were the individual shot scores for each of the marksmen?

Time Warp

An event took exactly 131 seconds. The first picture of a 24-hour digital clock shows the time when the event began, the second one when it ended. However, there was a strange breakdown, and some parts of the display are not visible; the nature of the breakdown was different for the two times. What are the two times?

Ex:

Beeline

Draw a single closed loop along the lines of the honeycomb pattern. A number within a cell indicates the number of the sides of the cell that are part of the path.

Penthouses

Place the twelve penthouses (shaped like Pentominoes) into the grid so that they do not touch one another, not even diagonally. They can be rotated, but not reflected. The grid includes special key symbols (illustrated below) for positioning the penthouses.

Pentominoes:

Key Symbols:

Example for 5 selected penthouses (1, 2, 4, 6, 11):

Security System

A security system is accessible using a key card with 33 possible hole positions. However the "combination" that opens the lock looks at only 12 specific hole positions: any key with a subset of holes matching this unknown combination will open the lock. Of the 10 cards shows below, exactly two will open the lock. Which ones?

Pearls

Locate the pearls hidden among the shells. Each arrow points to exactly one pearl, and each pearl is pointed to by exactly one arrow. And in no case are pearls found in neighboring shells. 

Days

Enter the days of the week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday) into the grid below. They should be written sequentially, from left to right and top to bottom, jumping over the intervening black spaces. No square can be left blank, and each name is written in its entirety. The names can appear in any order, but each must appear at least once (some will appear more than once). The same letter cannot appear more than once in a row or column. Two letters are already placed in the grid.

Strange Dice

Determine the number and orientation of the pips on the last die so that the logic of the arrangement is maintained.

Corners

What is the missing shape?

Equation

Fill in the eight missing digits so that the equation is correct and uses each of the digits from 0 to 9.

Carousel

Fill in the missing numbers on the carousel so that the same rule applies to all connected circles.

Magnets

Locate the position and orientation of magnetic and non-magnetic plates in the grid below. Each magnetic plate has two halves with opposite polarity: positive (+) and negative (-). When two magnetic plates touch each other on edge, the adjacent halves must have opposite polarity. The non-magnetic plates have no polarity and can appear anywhere. The numbers of positive and negative charges in each row and column are indicated to the right and below the table. One plate has already been placed in the diagram.
