This is a game where you need to place an event in the correct place in a timeline.
The timeline is created by the events you're placing.
Your timeline has started with
Play by clicking and dragging the new event from the right to the timeline on the left, ordered by year. Early (past) on top and new (today) at the bottom.
You have 7 minutes to get at least 15 correctly placed events.
If you place an event incorrectly you will be penalized 30 seconds.
The timer only runs when you have an event to place so you can take a break between them.
Each turn you chose between two categories (they can be the same).
