This is the standard apterous game, with three types of round.

Letters round: Letter tiles are arranged face-down into two piles, consonants and vowels. One player chooses a pile and the top tile from that pile is revealed. A selection of nine tiles is generated in this way, and must contain at least three vowels and four consonants. The clock is started and the players have a fixed amount of time (typically 30 seconds) to come up with the longest word from the available letters. Each letter may be used only as often as it appears in the selection.

After the thirty seconds is up, the players reveal their words. Only the player with the longest word scores points (or both players score if their words are the same length). One point is scored per letter, except for nine-lettered words, which score eighteen points. If a player offers an invalid word then they score no points.

Numbers round: Players are given a selection of six numbers and a random three-digit target number, and must combine the numbers in the selection using addition, subtraction, multiplication and division to get as close as possible to the target. Numbers can be used as many times as they appear in the selection, and it is not necessary to use all the numbers. Decimals and fractions are not allowed - only whole numbers may be used at any stage of the calculation.

One player chooses how many "large numbers" appear in the selection, which are then drawn at random from 25, 50, 75 and 100; the remaining spaces are taken by "small numbers", drawn at random from 1 to 10. (The same small number can appear twice in the same selection.)

Points are awarded for the closest solution, and again both players score if the solutions are equally close. 10 points are given for an exact answer, 7 points for a non-exact solution up to 5 from the target, and 5 points for a solution between 6 and 10 from the target. If neither player can get within 10, no points are awarded.

Conundrum: This round is a race to solve a nine-lettered anagram. The first player to buzz with the correct answer is awarded 10 points, and each player may guess only once.
