**The Challenges**

We have a vast collection of number puzzles, five of which are posted each day, and the majority are our very own creations.

There are seven categories you will see throughout the year:

**The Main Challenge** – involving different types of number puzzle gathered from all parts of the globe and will vary in content and difficulty from one day to the next.

**The 7puzzle Challenge** – linked to our signature puzzle board game, this is generally the easiest of the five daily number puzzles. Great for younger or less-confident students in improving their knowledge of mathematical terminology.

**The Roll3Dice Challenge** *(DAYS 1 to 10)* – puzzlers will be given seven groups of three numbers which replicate the rolling of three dice. The numbers in six of these groups will be able to arrive at the target number, but your task is to find the impossible group!

**The Lagrange Challenge** *(DAYS 11 to 250)* – named after the French-Italian mathematician who proved that every positive whole number can be made from adding together up to four square numbers. A medium-difficulty challenge where puzzlers must arrive at that particular day’s target number using his theorem.

**The Factors Challenge** *(DAYS 251 to 366)* – again related to that particular day’s number, puzzlers have to find which numbers listed, if any, are factors of the number in question (it will divide exactly into it). Good practice for ‘bus-stop’ division, and great to test some of the mathematical tricks available to find whether our number is a multiple of 2, 3, 4, 5 …

**The Mathematically Possible Challenge** – based on our best-selling arithmetic board game and designed to encourage creative number work. Challenges are also at the medium level of difficulty, but may take the longest time to solve. Requires perseverance to find the possible answers!

**The Target Challenge** – hardest of the challenges, puzzlers must insert the given numbers into the correct gaps to arrive at the day’s target number. Can sometimes be tricky but will satisfy greatly when solved. A knowledge of BIDMAS, indices and estimation is desirable, but it will also help to think logically.
