The Main Challenge
If you allocate each letter of the English alphabet a numerical value as follows: A=1 B=2 C=3 . . . Z=26, the value of the word ‘CAT’ would be 24, simply calculated by doing 3+1+20.
Following this rule, what is the value of the word ‘PUZZLED‘?
The 7puzzle Challenge
The playing board of the 7puzzle game is a 7-by-7 grid containing 49 different numbers, ranging from 2 up to 84.

The Roll3Dice Challenge
From six of the seven groups of numbers below, it is possible to make today’s target number of 4 when each number in the group is used once and + – × ÷ is available:
- 1 1 2
- 1 2 4
- 1 4 5
- 2 4 4
- 3 3 3
- 4 4 5
- 5 6 6
Which is the only group that CANNOT make 4?
The Mathematically Possible Challenge
Using 4, 5 and 10 once each, with + – × ÷ available, which FOUR numbers is it possible to make from the list below?
6 12 18 24 30 36 42 48 54 60
#6TimesTable
The Target Challenge
Can you arrive at 4 by inserting 1, 3, 5 and 7 into the gaps on each line?
- (◯+◯)–(◯+◯) = 4
- (◯+◯)÷(◯×◯) = 4
- √(◯×◯–◯×◯) = 4
- (◯–◯)×(◯–◯) = 4
- (◯²×◯+◯)÷◯ = 4 (there are 2 ways)
