# 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
Play it in your browser at <https://hugoocoto.github.io/blackjack/>, or 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).
- **Android:** install `hushjack-android.apk` (allow installing from unknown
sources when asked). It plays in landscape with touch. The records board
and the card back choice aren't saved there yet.
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 and setup |
| `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 |
| `B` | Change the card back |
| `F` | Fullscreen |
| `Esc` | Leave: shows the records board; `Esc` again quits |
You can also click every button. To cut, move the cut card with the mouse
or the arrow keys, then click.
When you leave, the records board shows your best and roughest sessions. If
this one makes it, type your initials and press `Enter`. The board and your
card back are kept in `~/.local/share/hushjack` (Linux),
`~/Library/Application Support/hushjack` (macOS) or `%APPDATA%\hushjack`
(Windows). In the browser, `Esc` does nothing and nothing is kept.
Two wins in a row set the betting spot on fire, and it grows with every win.
## 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.
