Slot Machine

This slot machine is written in Vue (Vue 3 using their options API), Typescript and PostCSS with Vite as our build and dev tool. It includes a bot which allows for getting an idea of your chances without having to do any probability math. The code was originally written during a long trip in the car, as a playfull experiment and an attempt to inspire my kids, which it failed to do. Feel free to use, play with or fork this project. A live demo lives at https://slotmachine.hofmeijer.me.

Running the Slotbot 🤖

• The slot-machine can be run by a bot by setting the slotbot queryParam to true: <url>?slotbot=true.
• When you want the bot to briefly stop when locking or winning add the aditional show param: <url>?slotbot=true&show=true.
• Check the browsers developer console for the results.

The code for the bot can be found in src/mixins/slot-bot.ts. Here you can change the way the bot locks reels (defaults to all doubles except for lemons), change the number of sets it will run (BOT_SET_COUNT) and the number of spins per set (BOT_SPIN_COUNT).

You can also change your chances by changing the value of each symbol (src/symbol-data.ts) or by changing their count in each reel (src/utilities/get-symbol-composition.ts).

Standard Vue Info

Recommended IDE Setup

VSCode + Volar (and disable Vetur) + TypeScript Vue Plugin (Volar).

Type Support for .vue Imports in TS

TypeScript cannot handle type information for .vue imports by default, so we replace the tsc CLI with vue-tsc for type checking. In editors, we need TypeScript Vue Plugin (Volar) to make the TypeScript language service aware of .vue types.

If the standalone TypeScript plugin doesn't feel fast enough to you, Volar has also implemented a Take Over Mode that is more performant. You can enable it by the following steps:

1. Disable the built-in TypeScript Extension
   1. Run Extensions: Show Built-in Extensions from VSCode's command palette
   2. Find TypeScript and JavaScript Language Features, right click and select Disable (Workspace)
2. Reload the VSCode window by running Developer: Reload Window from the command palette.
