Odd One Out: which one doesn't belong?
Odd One Out shows you four historical events at a time. Three of them happened in the same century, or later in the run the same decade. Find the fourth before the clock runs out.
How to play
- Read the four events and tap the one from a different time.
- For the first 10 questions the three share a century. After that they share a decade, and the odd one gets closer.
- You have 15 seconds for each question. A wrong tap or running out of time costs a heart, and three end the run.
- Get 10 right in a row to win back a lost heart.
- Every answer shows all four years, so you learn as you go. Share your score and see if your friends can beat it.
