Most people like betting and even more like winning. You can do both of them and you can see how by watching this video. You will always win the bets unless your opponent is very clever or already know them. Con artists know all of them so you can’t beat them at their own game. Also keep in mind that if you bet a round of drinks with your friends is fun but betting money with strangers could end up badly.

Another easy one in the sub-category Find the numbers which is similar to the previous one. The first seven numbers are given and you are asked to find the next one. More than one ways can lead you to the correct result but it is not required to provide how you figured it out. There are not assumptions to take into consideration. Everyone lies but numbers don’t. If you find the answer leave a comment and I will let you know if it is correct or not.
A simple challenge to keep you active in the Find the numbers sub-category. I have received some complaints that most of the challenges are difficult so I have decided to put some easier ones. It is a famous sequence but don’t search for the answer if you want to work out your brain. I have put more numbers in the sequence to make it easier to figure it out. The goal here is to find the next number of the sequence. Find the number, leave a comment with the answer and I will let you know if your answer is correct. I can’t put an easier challenge than this because then it is now a challenge, it is a question. The point is to stress your brain.
This is the third challenge with the title “Find the numbers”. It requires both basic math knowledge and logic (or programming skills for brute force if you are too lazy to find the answer). Using all digits from 1 to 9, only once, you have to find the two numbers that give the highest product. For example 123456 * 789 = 97406784. In your answer you should include both numbers and their product and I will let you know if it is correct. Like all other challenges, if you find the answer post it in a comment and not by using the contact form. It is easier to check it and give you credit for it.
Previous ciphers are easier than this one but easy is not challenge. I suggest that you try yo decipher previous ciphers before this one to get an idea what is going on. Don’t send me email with the answer, just leave a comment. I try to encode small messages to make it a bit easier for you. This will keep you busy and I will not post more ciphers until at least three of you find the answer. Do you know that with exercise you can increase your IQ by about 35%? Force your brain to work harder and achieve greater mind fitness.
There are two kinds of people, the ones who like numbers and the ones who hate numbers. This challenge is for those who like numbers. This one will keep you busy for some time. Try to find the 10 digit number X0X1X2X3X4X5X6X7X8X9 so that the each X shows the times its number appears in the 10 digit number. X0 shows how many times 0 appears in the number, X3 shows how many times 3 appears in the number and so on. The difficulty of this is about 60/100 so let me know if you like it and if you want more difficult problems. After you find it, post it in a comment.
I like ciphers and I decided to give you one more. It is easier than the first cipher but every cipher has its own beauty. As an answer I like you to give me only one word and not the entire deciphered text. You will understand which one after you decipher the message. You don’t need to know which cipher this is in order to decipher the message. Enough with the introduction, the encrypted message is the following. Tell me the word you believe is the answer in a comment.
A friend of mine tried to challenge me yesterday with this one but I can say that it can be barely called a challenge. It took me less than a minute to figure it out and make him very disappointed. Don’t worry, you don’t have to be a mathematician to solve this. If you find the answer post it and I will let you know if it was the correct one. Also, if you have a difficult problem, cipher or puzzle you are very welcome to contact me and if I like it I will post it in my challenges. You don’t even need to have the solution and even if you have it don’t give it to me. I like to be challenged so challenge me.
A wise man whispers a number to each of his three apprentices, Alice, Bob and Carol. All numbers are integers larger than zero. Wise man tells to them that the sum of their numbers is 14 and ask them in order if they know all three numbers. Alice responds that she does not know the numbers but she knows that Bob and Carol have different numbers. Bob responds that he does not know but, even before hearing Alice response, he knew that all of them have different number. After hearing both responses, Carol says that she knows all three numbers. Which numbers have the three apprentices?
