Running .exe flash games on a Mac?

hello everyone,

i have searched quite a lot for this and i'm at an end of ideas where to look.
here's the thing. i own a computer but in my house there is also a mac i can use.
i do this when i cant use my PC unless i want to wake everybody up.
thus in the evening/night i crawl behind my mac where nobody is disturbed by me.
however, i have a few flash games (i.e. Adventures of anise, Beyond, MitsukoX) which cannot run on a Mac... or can they?
is there a way to run these kind of .exe games without using anything that requires me to emulate an entire Windows OS?
i tried winebottler and CrossOver. winebottler took away sound and Crossover couldnt even run them (needed an installer or something).
isnt there some magical program which converts .exe into .app?
I expect that the answer is a solid "No."
but nonetheless i wanted to try asking everybody here.

Best Regards.
