Tall Order is a trivia game about the size of things. You see one fact with its number, like the height of the Eiffel Tower. Then you guess whether the next one, say Big Ben, is higher or lower.
Get it right and that answer becomes the number to beat. The first questions are easy calls, and they get closer as your streak grows. Every few rounds the topic changes, from country populations to how fast a cheetah runs.
The daily game gives everyone the same ten questions, so you can compare scores. Numbers come from the UN, Wikipedia and Box Office Mojo. The game is free and supported by ads.
