How to play Odd One Out
- Four cards are shown, and each one is the odd one out for its own reason.
- Tap a label, then the card it describes. Each card needs exactly one label.
- Watch out for traps: some labels fit two cards or none, so they belong to nobody.
- Press Check. You get two tries per board; after that, the answer is shown.
- A game has 5 boards.
Tips
- For each label, count how many cards it fits. Only labels that fit exactly one card are reasons.
- Start with the most obvious difference, then look for subtler ones.
- On Numbers, think even and odd, multiples, primes and perfect squares.
- On Words, look at the first letter, double letters and word length.
About Odd One Out
Odd One Out turns a classic puzzle on its head: instead of one intruder, every card is different in its own way. It trains careful observation and the habit of checking an idea against every option.
Five levels cover shapes (color, size, outline, tilt), numbers (even, prime, square, multiples), English words (letters and length) and a mix of everything. Every board is generated, so you will rarely see the same one twice.
Points and badges
Finishing a game of Odd One Out earns points for your level. Four badges are waiting in this game, from bronze to diamond: each one says what to do and adds bonus points.
Questions
Why are some labels left over?
They are traps: each one fits several cards, or none, so it is not the reason any single card stands out.
What happens if I get it wrong twice?
The four right answers are shown, then the next board starts.
Which level is the hardest?
Numbers and Words ask for the most thinking; Mix keeps you guessing by switching between all of them.
