There is actually a pretty cool clone of Svoja igra (russian jeopardy clone <https://ru.wikipedia.org/wiki/Своя_игра>) sigame <https://vladimirkhil.com/si/game> which is popular with russian streamers and is open source. It is available as a web and native application, and has an extensive library of packs (sets of questions, tho many of them are in russian).
