Letters rounds

This is played to Hyper rules, however the first, sixth and twelfth letters all must be used in the word declared. Scoring is done by Gevin rules, so 12-letter words are worth 12 points instead of 24.

Numbers rounds

This is also played to Hyper rules, however the first number selected (the last reading from left to right) must be used in the solution. Note that the solution is still valid even if the red number leads to a "dead end"; for example, if 2 were the red number and 4500 the target, 6 − 2 = 4, 3 × 10 × 150 = 4500 would be a valid solution.

Conundrums

13 letters are shown, from which one 12-letter word is available. This word is the answer.
