You had better get your skates on, time is ticking! Detective level alone has 100 games and each game costs 25 keys. Yep, 2,500! keys will take you right through Detective to Virtuoso and the special avatar. You may not need or want to do that. Usually you can complete to the casket with the goodies by about 40% mark in Detective, give or take.

But to reach Detective, you have to do Novice, Amateur, Connoisseur and Sleuth. To be honest, cant remember how many games it takes. You move pretty quickly through the lower levels. They start off pretty cheap, 5 badges then 10, then 15 or whatever it is. And you collect incentives and level-up energy boosts along the way.

I suspect many players feel it is best not to repeatedly play the challenge room, preferring instead to intersperse with games in other rooms. Some folks gather keys by bingeplaying the cheaper premium rooms, however, which generally will give you more entry 'badges' in return for your energy spend than the non premium rooms do.

And also, some players feel it is best not to banish the challenge creatures all in one go either, and to try to keep at least a few pendants in the kitty until the end. I do it thay way, banish progressively.

And not every game pays you a pendant of course. Ya spends ya 25 keys and ya gets diddly! Prepare thyself for some frustration... Good luck!
