What does a random category generator do?
A random category generator picks a category for a list game, such as "Fruits" or "Things with wheels", so nobody has to think one up. Our Random Category Generator draws from 160 original categories in eight themes and three difficulty levels, and the panel below the tool adds a random letter for each round.
A good category is the heart of any list game: players race to write things that fit it, often starting with a chosen letter. Draw a category, add a random letter, and a new round is ready in one click. Every category here is family-friendly, so the game works for children, students and adults alike.
How do you use the Random Category Generator?
You use the Random Category Generator by setting how many categories you want, choosing a theme or difficulty if you like, and pressing Generate.
- Set the number. Type 1 to 20 in the How many box; the default is 3.
- Pick filters. Choose a theme such as Animals & nature and a difficulty of Easy, Medium or Hard.
- Generate. Press Generate, then press New letter in the panel below for a starting letter.
- Save or share. Copy the categories, download a CSV, or copy a share link so another group can play the same set.
Draw several categories at once to build a full game sheet with one column per category.
How do you play Name, Place, Animal, Thing?
You play Name Place Animal Thing, and similar list games, by writing one answer per category that starts with the same letter. It is a favourite in schools and homes across South Asia and beyond.
- Set up. Each player takes paper and pencil and draws a column for each category.
- Pick a letter. Use the random letter panel.
- Race. Start a timer, often one or two minutes, and fill every column.
- Score. Give 10 points for unique answers, 5 when two players write the same answer, and 0 for a blank.
Swap the classic four columns for random categories from our list to keep the game fresh every round.
Which themes can you choose?
You can choose from eight themes, with 20 categories in each.
| Theme | Example categories |
|---|---|
| Food & drink | Fruits, Street foods, Pizza toppings |
| Animals & nature | Sea creatures, Flowers, Animals that hibernate |
| Places | Capital cities, Rooms in a house, Islands |
| Things & objects | Things with wheels, Things that come in pairs |
| People & jobs | Jobs, Famous inventors, Family members |
| School & learning | Shapes, Musical instruments, Words with double letters |
| Sports & games | Board games, Water sports, Olympic events |
| Fun & silly | Things that fly, Excuses for being late |
Food and animals themes are the easiest starting point. Places and objects test general knowledge, jobs and school themes build vocabulary, sports themes suit active groups, and the silly theme brings plenty of laughs.
How hard are the categories?
The categories come in three levels. Easy categories, such as Colours or Pets, suit younger players and short rounds. Medium categories, such as Things in a bathroom, need a little more thought.
Hard categories, such as Words with a silent letter or Things that open and close, challenge older students and adults. Mix the levels to give everyone a fair chance, or let younger players use Easy categories while adults play Hard ones in the same game.
The letter matters too: common letters like S, B and C are easier than rare ones, which is why the letter panel can skip Q, X and Z.
Where can you use random categories?
You can use random categories anywhere a quick game helps. Here are some ideas.
- School: start a classroom lesson with a two-minute round.
- Travel: play out loud on a car journey, with no paper needed.
- Parties: run a team round at a party or gathering.
- Home: make it part of a weekly family night.
- Learning: use it as a brain warm-up or vocabulary practice for ESL learners.
How does the generator pick categories?
The generator picks categories by filtering the 160 categories to those that match your settings and then drawing from that filtered pool with your browser's cryptographic random source, so every matching category has the same chance. Nothing is sent to a server.
The draw uses the Web Crypto API (crypto.getRandomValues, documented on MDN Web Docs) with rejection sampling, then a Fisher–Yates shuffle. Each press is independent, and one list never shows the same category twice unless you switch on "Allow repeats"; repeats across separate presses are normal.
Frequently asked questions
Is the Random Category Generator free?
Yes, it is free, with no account and unlimited use on phones, tablets and computers.
How many categories should a round have?
Four to six columns work well for one round: enough to be a challenge, short enough to finish before the timer, whatever the letter.
Why skip Q, X and Z?
Very few words start with Q, X or Z, so rounds with them are much harder; the switch lets you include them for an extra challenge.
Can I use it in class?
Yes. Teachers use it as a quick warm-up or a vocabulary game.
