I made a GeoGuessr-like that asks you to guess where people are from based solely on hearing them read out a standardized passage in English. Many thanks to the GMU Speech Accent Archive for creating such a repository.
IIHGuessr
I set up a game that has you guess which among two Magic: The Gathering cards has the higher “improvement in hand” from a given best-of-one draft format. This is an imperfect proxy for card quality but I thought it could help some people drill a given format and also help them internalize general patterns about what makes a card strong in Limited.
