Following on from my Adventures in London post earlier check out this cool quiz I spotted in tube stations at the weekend.
You’ve got to find 75 tube stations cryptically hidden in the picture. Luckily there’s an online version you can take more time inspecting.
You can win different prizes depending on how many you find.
I found about 15 of the 75 before I had to get a tube map out! I’m on 42 now.
How many have you found?
