The House always wins.
But sometimes it can take time.
The House has to be patient. Sometimes, people work out how to cheat The House. Sometimes people run from The House. And sometimes, just sometimes, people get lucky.
So The House has developed tricks. ‘Free Gifts’, attractive girls and guys, bright lights, loud noises, all of them to lure people in.
The House didn’t care about what went on inside it, as long as it didn’t drive people away. The House just wanted as many people inside it at all times.
So The House could take one at a time.
