Hmm, I think I may have been playing the wrong games all along.
Down the Chimney
Let's face it, this is just too low volatility for anything significant to happen. If you somehow get a 500x you're probably in max win territory. I also doubt the "Grand" has ever been won on this one. It will keep you alive for a while, but just keep an eye on your balance and you will see how it only gets eaten, very slowly, but steady.

I had high hopes for this one as it is a fairly intriguing slot with lots of neat features. But it goes into balance eating mode before long, and with a higher min bet than the others, any recovery will quickly start to feel insurmountable. Certainly doesn't help that the game needs frequent reloads which in turn sets the bet to 5x higher than the minimum. Something I got burned on the other night, when I reloaded, put on 100 auto, and went outside for a bit. Luckily something had hit in that time, if it hadn't I could easily have lost like 400x in just a couple of minutes. I had even warned about this early on in the contest, so you see how easy it is to forget. Very unnescessary design. @AlexBragg
Treat Yo' Elf
Only played it very briefly since I'm mainly on bonus funds. Got the feature once and it left me with no desire to play this game further.
Carts of Cash Xmas
This'll be the game where I make my final surge towards the top of the standings, and is also the game producing the altogether best hit so far in the contest! Disliked it at first but I've just enjoyed a real good hour or two of playing it, more than doubling my mortally wounded balance thanks to a very frequent rate of the respins feature. These respins have all kinds of neat potential, with things like collects, quadruple cells, or boosters. I've hit total wins just under 250x three times already and I think it might just have an 800x hidden somewhere in there, which I feel good about finding sometime before my balance runs out!
