Type each word you find in the 'Enter Word' box and hit return. All the words you enter will appear in the box to the right. As you enter the words you will be given your running score as a percentage of the total possible number of words in the puzzle.

All words in the Concise Oxford English Dictionary are eligible with the following exceptions:

• Proper nouns (those with an initial capital letter);
• All plural nouns, plus plural pronouns and possessives;
• Third person singular verbs (those mostly ending with an 's');
• Hyphenated words, including prefixes and suffixes;
• Contractions, abbreviations and acronyms which use a capital letter or letters;
• Any words described as being vulgar slang;
• Variant spellings of the same word (where a more commonly accepted variant is also eligible);
• US variant spellings of words for which there is an English equivalent that appears in the dictionary (but not US words for which there is no English equivalent).

Forms of verbs (past tenses, past participles and present participles) and forms of adjectives (comparatives and superlatives) which are formed regularly are eligible even where they do not specifically appear in the dictionary.

How we score it

The par target is to discover 65% of the total possible words within 20 minutes. If you can attain that target you will score 200 points.

Your score will be increased or decreased by 20 points for every 5% of the words discovered above or below that par target. No points are awarded for finding fewer than 20% of the words.

If you wish to continue playing the game beyond the target time of 20 minutes your score will be reduced by 5% for every part minute you use. No points are awarded if you exceed a time of 40 minutes.

Examples

1. 58% of words discovered in less than 20 minutes: Score 160
2. 58% of words discovered in 22 mins 30 secs: Score 160 - 24 = 136
3. 72% of words discovered in less than 20 minutes: Score 220
4. 72% of words discovered in 21 mins 30 secs: Score 220 - 22 = 198
5. 36% of words discovered in less than 20 minutes: Score 80
6. 36% of words discovered in 20 mins 30 secs: Score 80 - 4 = 76
