// crappy blackjack v1

// i can't get anywhere with more complicated projects
// so i went all the way back to teenager-level shit
// and made something as simple as possible

// use this simple example and make it better

// this is a simple blackjack game

// rules:
// https://bicyclecards.com/how-to-play/blackjack/

// missing:
// - card faces
// - an actual deck
// - ace rules
// - dealer must stop at 17 or higher
// - ties are no win/loss
// - natural 21 is auto win unless dealer also has 21
// - splitting pairs
// - double down
// - insurance
