# bootjack
A bootable Blackjack written in 508 bytes.
## Limitations
This is a minimal blackjack so its single deck and missing bets, splits, etc.
I ran out of space to print scores per round, but blackjack isn't hard to calculate.
I also ran out of space for good prompts, so when its the player's turn:
`h=hit`, `q=quit`, and any other char is considered a stand.
The same type of logic exists for when the game is over. `q=quit` and any other
char is considered to be "play again".
## Running Locally
Build and run via QEMU with - `make qemu`
I also made a little C prototype in [c/](c/) that can be
run with - `gcc c/blackjack.c -Wall -o blackjack; ./blackjack`.
