Countdown Strategy Guide: Letters, Numbers and the Conundrum

Countdown has been on British television since 1982, and its format is beautifully simple: letters rounds, numbers rounds, and a final nine-letter Conundrum, each against a 30-second clock. Whether you play along from the sofa or practise seriously, a little method goes a long way. This guide goes deeper than the quick tips on our Countdown solver page, with worked examples you can follow step by step.

The letters round

Picking your letters

The contestant choosing the letters calls "vowel" or "consonant" nine times, and the selection must include at least three vowels and at least four consonants. Within those limits, the most common choices among strong players are three or four vowels. Four vowels and five consonants gives a flexible mix; three vowels and six consonants can produce longer words if the consonants are friendly ones such as R, S, T, N and L.

Five vowels is rarely a good idea. Vowels are easy to place in short words but run out of partners quickly, and an awkward vowel such as U or a second I can sink a long word.

Bank a word, then build

Use the first few seconds to find any solid word of five or six letters and hold it in your head. Everything after that is a bonus. Many players lose points not because they could not find a long word, but because they chased one and ended up declaring nothing.

Look for endings first

Endings are the fastest route to long words. As soon as the letters appear, check for:

  • -ING: set I, N and G aside and look for a stem in the remaining six letters.
  • -ED and -ER: very common, and they turn short verbs into longer words.
  • -EST, -IER, -ION and -TION: less common, but they produce seven- and eight-letter words.

A worked example

Suppose the letters are G R A D I E N T S: three vowels (A, I, E) and six consonants.

  1. Spot -ING. The remaining letters R, A, D, E, T, S give TRADING (7 letters) immediately.
  2. Now notice that R, E, T, S, I, N and A are all there. Those seven letters are famously productive. Adding the D gives STRAINED (8 letters).
  3. With a full eight-letter word in hand, check whether the last letter fits. Adding G to STRAINED gives GRADIENTS, a full nine-letter word worth 18 points.

The route matters as much as the answer: bank a seven, notice a familiar group of letters, then try to extend.

The numbers round

Choosing your numbers

Contestants choose six numbers from four large ones (25, 50, 75 and 100) and twenty small ones (two each of 1 to 10), and a random three-digit target appears. One large and five small, or two large and four small, are the most popular choices because they give both reach and fine control. Six small numbers looks friendly but often makes big targets hard to reach.

A three-step method

  1. Find an anchor. Look for a multiple of a large number that lands close to the target.
  2. Build the multiplier from the small numbers if the one you need is not on the board.
  3. Adjust with the numbers left over, by adding or subtracting the difference.

Worked example 1

Numbers: 75, 50, 8, 5, 3, 1. Target: 617.

  1. Anchor: 75 + 50 = 125, and 125 × 5 = 625. That is just 8 above the target.
  2. Adjust: 625 − 8 = 617. Done.

Overshooting and subtracting back is often easier than trying to land exactly from below.

Worked example 2

Numbers: 100, 25, 9, 6, 4, 2. Target: 831.

  1. Anchor: 100 − 25 = 75. Seventy-five is a useful number because 75 × 11 = 825, which is close to 831.
  2. Build the multiplier: there is no 11 on the board, but 9 + 2 = 11.
  3. So: 75 × 11 = 825.
  4. Adjust: 825 + 6 = 831. Done, and the 4 was not even needed.

When the exact answer will not come

Being within 5 of the target still scores 7 points, and within 10 scores 5. If the clock is running out, lock in your closest result rather than abandoning it for a solution you might not finish. Scoring something is always better than scoring nothing.

The Conundrum

Every game ends with the Conundrum: a nine-letter word, scrambled, worth 10 points to whoever buzzes in first with the answer. A few habits help:

  • Look for endings such as -ING, -TION, -MENT, -NESS and -ABLE first. Nine-letter words very often have one.
  • Ignore the decoy. The scrambled letters are usually arranged to look like other words. Try to see the letters as a set, not as the words they appear to spell.
  • Try common beginnings such as RE-, UN-, IN-, DIS- and PRE- once you have spotted an ending.

How to practise

The fastest way to improve is to review your rounds. After you play along, put the letters or numbers into our Countdown solver and see what you missed. Over time you will start to recognise the same helpful letter groups and number patterns without thinking.
