This is all speculation, but still...
1st animation: We are presented to the Slot Machine Titan, which seems to fluctuate in mood depending on how the slots come up... Bipolar Disorder will give you n^3 possible states of mind. Good luck! :-P
2nd animation: we are introduced again to the concept of luck, this time regarding whether your coin reaches the bottom of the well or not. Curiosity and not a small amount of greed gets our ectoplasmic friend in quite a pickle!
3rd animation: We seem to be drawn back to the Titan, which seems to be malfunctioning... Surrounded by what appears to be a boneyard, one of our curious friends bides its time, not wishing to push its luck... while another is pulled out of the frame by what I can only call Death... and Death always gets its due.
Anyway, just my two cents. ;-)
