# Hushjack
<img src="assets/icon/hushjack.png" alt="" width="96" align="right">
A small pixel-art blackjack table for one player, written in Rust. It opens
straight into the game. A dealer hand-shuffles 6 decks the way a casino does,
you cut, and you play from the shoe for as long as you like.
## Download
Get the build for your system from the
[releases page](https://github.com/hugoocoto/blackjack/releases), unpack it and
run `hushjack`. The game is a single file.
- **Windows:** the game isn't signed, so SmartScreen may warn you. Click
*More info*, then *Run anyway*.
- **macOS:** the game isn't signed either, so macOS blocks it the first time.
Run `xattr -d com.apple.quarantine hushjack` in the unpacked folder, or
allow it in *System Settings → Privacy & Security*. The build works on
Apple Silicon and Intel Macs.
- **Linux:** x86_64 only. It needs ALSA (`libasound2`), which most desktops
already have. Run `./install.sh` in the unpacked folder to add it to your
menu (it installs into `~/.local`, no root needed; `./install.sh --uninstall`
removes it).
With Rust installed, you can also get it from [crates.io](https://crates.io/crates/hushjack):
```sh
cargo install hushjack
hushjack --install-desktop # optional: add it to your app menu (Linux)
```
`hushjack --uninstall-desktop` removes the menu entry again.
On Linux this needs the ALSA development files (`libasound2-dev` on
Debian/Ubuntu, `alsa-lib-devel` on Fedora, `alsa-lib` on Arch).
## Play
To build it yourself instead:
```sh
cargo run --release
```
To install your own build into `~/.local` with a menu entry, run
`cargo build --release` and then `packaging/linux/install.sh`.
| `Space` | Deal, stand, decline insurance, skip the shuffle |
| `H` `S` `D` `P` | Hit, stand, double, split |
| `I` / `N` | Take or decline insurance |
| `←` `→` or mouse wheel | Change your bet |
| `C` | Show or hide the strategy chart |
| `F` | Fullscreen |
| `Esc` | Quit |
You can also click every button. To cut, move the cut card with the mouse
or the arrow keys, then click.
## Rules
- 6 decks. Blackjack pays 3:2. The dealer stands on all 17s and peeks for
blackjack.
- You can double on any two cards, including after a split. You can split
up to 4 hands. Split aces get one card each.
- Insurance is offered when the dealer shows an Ace. It costs half your bet
and pays 2:1.
- There is no surrender.
- You start with 1000 credits. Your balance can go negative, and the game
never ends.
- The dealer's cut card sits about one deck from the end. When it comes
out, that hand is the last one, and then the dealer shuffles again.
The strategy chart (`C`) shows basic strategy for these rules. During your
turn, it marks the play for your hand.
## Requirements
Rust (stable). On Linux, sound needs ALSA.
