The firm took part in a $22m financing round for Plain Vanilla, which also received repeat backing from Tencent Holdings.
QuizUp has racked up more than five million users since its release last month, with each user spending an average of half an hour per day using the app.
Sequoia Capital partner Roelof Botha said, “The level of engagement in QuizUp is stunning.
“Thor and his team struck the perfect balance of human interaction and gameplay to create an experience that is resonating with millions of gamers around the world.
“We’re thrilled to support Plain Vanilla’s continued growth and can’t wait for all that’s to come in the new year.”
Last month Andreessen Horowitz re-upped its investment in mobile games developer TinyCo by joining a $20m financing round led by Pinnacle Ventures.
TinyCo previously picked up $18m from Andreessen Horowitz and angel investors Ron Conway and Keith Rabois in 2011.
It said the latest funding would be used to hire extra design and production staff to push for higher quality in mobile game development.
