Numbers Round

• Six, face-down, numbered tiles are selected from twenty-four shuffled tiles.
• The tiles are arranged into two groups: Large Numbers and Small Numbers.
• There are four numbers in the big set { 25 , 50 , 75 , 100 }
• There are twenty numbers in the small set, two each of the numbers 1-10
• One contestant selects as many numbers as desired (unseen) from the large set (between none and all four), and the balance are pulled from the small set to make six numbers in total.
• A random three-digit target number is then chosen by a computer.
• The contestants are given 30 seconds to get as close as possible to the chosen target by using just the four basic arithmetic operators + - × ÷ (and brackets)
• Not all the digits need to be used.
• Concatenation of digits is not allowed (You can’t use a “2” and “2” to make “22”).
• At no intermediate step in the process can the current running total become negative or involve a fraction.
• Each numbered tile can only be used once in the calculation.

Numbers Scoring

• 10 points are awarded for correctly getting the exact solution.
• 7 points are awarded for getting within 5 of the required solution.
• 5 points are awarded for getting within 10 of the required solution.

Letters Round

• The contestant in control chooses between two stacks of letter tiles, one containing vowels and the other consonants.
• This is done nine times, and the final grouping must contain at least three vowels and four consonants.
• The contestants then have 30 seconds to form the longest single word they can, using the nine revealed letters; no letter may be used more often than it appears in the selection.
• The frequencies of the letters within each stack are weighted according to their frequency in natural English, in the same manner as Scrabble. For example, there are many Ns and Rs in the consonant stack, but only one Q
• Any word which appears in the Oxford Dictionary of English is valid,[48] as well as accepted forms of them that may not be explicitly listed. Examples:
• Common nouns and their plurals
• Verbs and their inflections (e.g. "escape," "escaped," "escaping")
• Comparative and superlative forms of adjectives (if the adjective is more than one syllable, the form must be explicitly listed)
• Plurals of foods specified as mass nouns that may be ordered in restaurants (e.g. "pastas" as in, "I'll have two pastas")
• Words that are not allowed include:
• Capitalised words, including proper nouns (e.g. "Jane" or "London")
• Hyphenated terms
• Words that are never used alone (e.g. "gefilte"; only used as part of "gefilte fish")
• American spellings of words (e.g. "flavour" and "signalled" are allowed, but "flavor" and "signaled" are not)

Letters Scoring

• The contestant with the longer word scores one point per letter, or 18 points if they have used all nine.
