Speaking of maths here is this great logic problem I got given at a summer school.

• You have ten wine glasses.
• You have 1000 bottles of wine, one of which contains deadly poison.
• You have ten cats as wine-testers.

You can pour as much or as little wine into each glass as you want, and you can combine any number of wines together in the same glass. The only rule is that all the cats must drink at the same time, and no cat can drink more than once.

How can you combine the wine so that you know definitively which of the bottles is poisonous? How can you show simply that such a solution is possible?

# Summer Boredom Blaster 11: More Logic Puzzles

In this new series of SOLARO blog entries, we are going to explore some fun, exciting, and easy ways to ensure that students keep learning through the summer.  Over the next few months, SOLARO is going to publish one fun activity per week, taken from our vast pool of resources, which are usually only available to SOLARO subscribers. We believe our content is superior to all other online learning resources on the Internet; therefore, we are so excited to be able to share a little bit with our blog readers.

So stay tuned and get your kids involved in some brain-stimulating activities that are sure to drag them away from the video games. (At least for a while!)

In our last blog post, we gave an introduction to GridWorksTM logic puzzles, and today, we’re going to take it one step further.

To recap, GridWorksTM puzzles are found on Puzzles.com, and each puzzle consists of a 3-by-3 grid containing 9 different tiles of three colours and three shapes.

Each puzzle comes with one or more clues that provide enough information to completely solve the puzzle. Positive clues are shown on a light-coloured background, and they show arrangements of tiles that must occur at least once in the puzzle.

Some puzzles also have clues that appear on a blue background. These are negative clues, and they show arrangements of tiles that cannot appear at all in the puzzle. You can read more about negative clues here.

Puzzle 63 has one positive clue and two negative clues.

The positive clue can be used to fill in most of the puzzle.

Clue 2 is a negative clue.

According to this clue, there can never be a green triangle in any square with two squares above it. This means that the green triangle cannot go in either square 7 or square 9. The only place for it to go is square 2.

According to negative clue 3, the yellow triangle cannot go in a square with two squares to the right of it.

This means that the yellow triangle must go into square 9. Square 7 will contain a blue circle, which is the last missing tile.

In puzzle 191, there are 3 positive clues and 2 negative clues.

Each of the three positive clues could appear in any of the three columns of the grid. For example, clue 1 could appear in the right-hand column, in the centre column, or in the left-hand column.

You need to use the negative clues to correctly order the positive ones.
If you put clue 2 to the right of clue 1, then negative clue 4 is violated.

Clue 2 cannot go to the left of clue 1 either.

This means that clues 1 and 2 cannot be adjacent, so clue 3 must be between them:

Negative clue 4 shows that a green shape is never found to the right of a blue shape. This means that there is only one possible way to arrange the positive clues.

Use the negative clues again to decide what needs to go in the remaining three empty squares.

Puzzle 193 does not have any positive clues at all. Five negative clues give all of the information that is needed to solve the puzzle.

To solve this puzzle, start by looking at the colour clues. According to clue 1, a yellow shape cannot be to the right of any other square.

This means that that all three yellow shapes must be along the left edge of the puzzle.

Clue 3 tells you that a green shape can never be located to the right of a yellow one.

This means that all of the green shapes must be along the right edge, and the blue shapes are in the middle.

Clue 4 shows that a circle can never be placed in a square that has another square diagonally above and to the right of it.

This means that the only squares that may contain a circle are squares 1, 2, 3, 6, and 9.

Squares 1 and 2 must be circles because there has to be a yellow circle and a blue circle. There is still no way to determine which of the three green squares will be a circle.

Clue 5 shows that a triangle can never be placed in a square that has another square diagonally below and to the left of it.

This means that the only squares that may contain triangles are squares 1, 4, 7, 8, and 9.

Squares 8 and 9 must be triangles because there has to be a green triangle and a blue triangle. There is still no way to determine which of the two remaining yellow squares will be a triangle.

Most of the odd-numbered puzzles can be solved using only positive and negative clues. The even-numbered puzzles may also contain clues that rotate or reflect. You can find more information on these kinds of clues here. There are more than 200 puzzles on the website, so that should be enough to blast your boredom for at least a couple of hours!

# The Most Intelligent Prince

A king wants his daughter to marry the smartest of 3 extremely intelligent young princes, and so the king’s wise men devised an intelligence test.

The princes are gathered into a room and seated, facing one another, and are shown 2 black hats and 3 white hats. They are blindfolded, and 1 hat is placed on each of their heads, with the remaining hats hidden in a different room.

The king tells them that the first prince to deduce the color of his hat without removing it or looking at it will marry his daughter. A wrong guess will mean death. The blindfolds are then removed.

You are one of the princes. You see 2 white hats on the other prince’s heads. After some time you realize that the other prince’s are unable to deduce the color of their hat, or are unwilling to guess. What color is your hat?

Note: You know that your competitors are very intelligent and want nothing more than to marry the princess. You also know that the king is a man of his word, and he has said that the test is a fair test of intelligence and bravery.

# Late for a Party Logic Puzzle

Welcome to our Friday Puzzle Time. It is our hope that you can use these puzzles in your classroom to liven up Friday afternoons and really instil a love of math and logic in your students.

Three hungry lynx and three chubby capybaras have a party to attend. The party is on the other side of a gorge. The only way across is a manual gondola with a maximum capacity of two animals. The lynx forgot to eat before the party, and their tummies start to growl. To prevent an unfortunate event, there can never be more lynx than capybara together on either side of the gorge.

How can the animals cross the gorge in five steps if the gondola has to be returned to the starting side manually?

Update: The solution to this puzzle will appear on Tuesday, 22 January. We have something special coming for Martin Luther King, Jr. Day on Monday. Don’t change that dial!
