**The Challenges**

Five number puzzles are now posted each day, thus adding to our already vast collection of challenges. The daily categories are:

**The Main Challenge** – involving different types of number puzzle gathered from all parts of the globe, including many of our own creations, 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 Lagrange Challenge** – 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 our puzzlers have to try and arrive at that particular day’s target number using *Lagrange’s Theorem*.

**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. Can you find the possible answer(s)? Requires perseverance!

**The Target Challenge** – hardest of the challenges, puzzlers must insert the given numbers into the correct places 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 are desirable, but it also helps to think logically and have lots of patience.
