Yes, running a combination of talimans and playing premium rooms will yield the most keys for the event challenge. Or running a SOV and going to the more expensive premium rooms can yield 8 per visit. That is generally how I finish up at the end. But, you seem to get the idea. You can message one of the players who did finish quickly, on their wall, and maybe they can offer another tip.
