Wikitrivia is a neat web game that draws from Wikipedia and Wikidata. You are presented a series of cards with a person, place, event and a verb like “born, died, ended”… You must then drag to the appropriate spot on a timeline below.
It lights up green if it is in correct place, or it moves there and turns red, and also displays the actual year. Once on the timeline, the card can be flipped for a summary and a link to the full article for more information.
I find it frustrating because I think I should do better. I also wonder if there’s a way to correct cards when they’re wrong. I’m pretty sure Colt Firearms didn’t start in 69 AD.
