Problem 21 - Sudoku has a little brother. Its name is KAKURO
What is Kakuro?
Kakuro logic puzzle that is often referred to as a mathematical transliteration of the crossword. The original English name was Cross Sums but the Japanese name Kakuro, abbreviation of Japanese kasan kurosu, (加算クロス, addition cross) id the most popular name. The popularity of Kakuro in Japan is immense, second only to Sudoku.
Rules
Kakuro puzzles resemble crosswords which use numbers instead of words. The aim of the game is to fill all the blank squares in the grid with only the numbers 1-9 so that the numbers you enter add up to the corresponding clues.
each run of numbers (answer) can only contain each number once!

Problem 20 - Switches and Bulbs
Imagine you are in a room with 3 light switches. In an adjacent room there are 3 light bulbs (all are off at the moment), and each switch belongs to one of the bulbs. It is impossible to see from one room to another. How can you find out which light switch belongs to which light bulb, if you may enter the room with the light bulbs only once?
Problem 19 - Trick Donkeys
Sam Loyd' was a well known puzzle expert during the 19th century. His most famous puzzle was the "Trick Donkeys", firstly introduced in 1857. You must cut the drawing along the dotted lines and rearrange the three pieces so that the riders appear to be riding the donkeys.

Problem 18 - The Tower of Hanoi
The Tower of Hanoi or Towers of Hanoi is a mathematical game or puzzle. It consists of three pegs (sticks), and a number of disks of different sizes which can slide onto any peg. The puzzle starts with the disks neatly stacked in order of size on one peg, the smallest at the top, thus making a conical shape.
The goal is to move all the discs from the left peg to the right one, obeying the following rules:
* Only one disk may be moved at a time.
* Each move consists of taking the upper disk from one of the pegs and sliding it onto another peg, on top of the other disks that may already be present on that peg.
* No disk may be placed on top of a smaller disk.
History:
The puzzle was invented by the French mathematician Édouard Lucas in 1883. There is a legend about an Indian temple which contains a large room with three time-worn posts in it surrounded by 64 golden disks. The priests of Brahma, acting out the command of an ancient prophecy, have been moving these disks, in accordance with the rules of the puzzle. According to the legend, when the last move of the puzzle is completed, the world will end. The puzzle is therefore also known as the Tower of Brahma puzzle. It is not clear whether Lucas invented this legend or was inspired by it.
Your Mission:
Practice and understand the main principles using three and four disks.
The winner will be the student who will move all five disks from the left to the right peg.
Take a screen capture once you are done and send it to me (or else print it out).

Congratulations for figuring out the first sudoku puzzle.
Here is a new one … a bit more complicated …

Sudoku is a famous logic-based number placement puzzle.
The objective is to fill a 9×9 grid so that:
- each column contains the digits from 1 to 9, only one time each
- each row contains the digits from 1 to 9, only one time each
- each of the nine 3×3 boxes contains the digits from 1 to 9, only one time each
The puzzle setter provides a partially completed grid.
Here is the first Sudoku grid. We must fill it in. Remember in each column should be all the digits from 1 to 9, but also in each row and and 3x9 box.
Good Luck.

Problem 10
Habiba and Wafaa woke me up at 7.40am to be the first to give the answer. Unfortunately, both answers were wrong. Starting today, if you come before 7.45am you'll have to bring coffee to your favourite Maths teacher. Congratulations Fatma N. for finding the correct house!

Problem 7
Great job Wafaa & Manar ! Welcome to the club of the Maths Puzzle Masters (MPM club).
Tangram (Chinese: 七巧板; literally "seven boards of skill") is a very old Chinese dissection puzzle. It consists of seven pieces, called tans, which fit together to form a shape of some sort. The objective is to form a specific shape with seven pieces. The shape has to contain all the pieces, which may not overlap.
Here are the seven pieces.
Using these 7 pieces, we can make hundreds and hundreds of different shapes. Here is the first one I would like you to do.
To score one point you need to:
- make the seven pieces using quality paper or else cardboard.
- show me how to position the seven pieces to get the appropriate shape.
There will be several rounds for this problem. I would like more people to be involved with the maths Puzzles. Tangram is fun, you'll love it!
Problem 6
Congratulations Fatma for having found the answer and also for all the hard work. Fatma is now the leader of the puzzle competition, who will be the lucky winner?
Pentomino is a very famous puzzle game. It consists of twelve figures called pentominoes.
A standard pentomino puzzle is to tile a rectangular box with the pentominoes, i.e. cover it without overlap and without gaps. Each of the 12 pentominoes has an area of 5 unit squares, so the box must have an area of 60 units.
The winner will be the person who will come to class and who :
- will have made the 12 pentominos
- will be able to construct a rectangle 6 x 10
Have a look at the following file to know the shapes of the pentominoes.
This is a rather difficult puzzle, the winner will get 2 points this time.
Good Luck

Problem 5
A curious man arrives on the shore of Gluglu Island, in the middle of the Pacific Ocean. This island is unique in that it is inhabited by two tribes: the vegetarian truth tellers, who always tell the truth, and the cannibals who always lie. He makes his way from the shore until he meets a native who is standing at a fork in the road. One way leads to the cannibal's village, the other to the vegetarian's. She does not know from which tribe the native comes.
What one question can our curious explorer ask in order to establish which of the two roads leads to the vegetarian's village? His question must be non-compound ie not containing "and", "but", "or" etc…

Problem 4
Congratulations to Fatma who found the answer of problem which was rather difficult.
Here is the new problem:
Three friends have a nice meal together, and the bill is $25
The three friends pay $10 each, which the waiter gives to the Cashier
The Cashier hands back $5 to the Waiter
But the Waiter can't split $5 three ways, so he gives the friends one dollar each and keeps 2 dollars as a tip.
They all paid $10 and got $1 back. $10-$1 = $9
There were three of them 3 X $9 = $27
If they paid $27 and the waiter kept $2: $27+$2=$29
Where did the other dollar go? $30 - $1 = $29

Problem 1
Last vacation, my cousin came over to stay at my home. We made the most of her stay at my place… and I even earned a few chocolates.
Everyday, we would play a game of chess. Whoever lost the game owed a chocolate to the other. After the last game we played (that was the day she was to leave), we counted the number of games each of us had won and lost. Wow! I had won more than her. So, she handed me 16 chocolates… though she herself was the winner in 8 games.
How many days did my cousin spend at my place?
