Slot machine payout calculation I want to create a 5 reels slot machine calculation system and I'm not sure what approach to take. I understand that there is a lot of math within it, especially if I want the machine to be enjoyable. For a single machine, it is working fine, but my machine having 2 cores and I want to make available more cores. So I decided to join 3 more machines and now all 4 machines are connected using LAN. I am able to access the other machines using IP address in web browser also. In cases of more complex software, ports were achieved by first designing and implementing a one off virtual machine, then simply porting the virtual machine to the different platforms. See ScummVM, Z-machine, Another World, etc. Surely that threw away some notion of efficiency.
Create an extremely biased, web-based slot machine game.
Features
- Faux-panoramic reel animations (without
<canvas>) - Support for single/multi-line reels and pay-lines.
- Pseudo-random selections by configured weight.
- Configurable RNG (to make it less biased)
- Easy to set-up and customize.

Dependencies
Installation
Install the package into your project using NPM, or download the sources.
Node Js Windows
Alternative
To add to an existing React project you can install this package using YARN.
Usage
There are two ways you can use this package. One is by including the JavaScript/CSS sources directly. The other is by importing the module into your component.
Script include
After you build the distribution sources the set-up is fairly simple..
Module import
If your using a modern framework like Aurelia, Angular, React, or Vue
HTML markup
Reels configuration
Outside of a reel image source, symbols must contain the following:
| Key | Description | Type |
|---|---|---|
| title | Name of the strip symbol | String |
| position | Symbol center (in pixels) calculated from the strip top | Number |
| weight | Selection weight (>1 increases odds) | Number |
Example
Methods
Game options
Customization and overriding defaults can be done using the following options:
| Option | Description | Type | Default |
|---|---|---|---|
| reelHeight | Reel background image height (in pixels) | Number | 1320 |
| reelWidth | Reel background image width. | Number | 200 |
| reelOffset | Reel background image vertical offset. | Number | 20 |
| slotYAxis | Slot vertical axis rotation (in degrees). | Number | 0 |
| animSpeed | Slot animation speed (in milliseconds) | Number | 1000 |
| rngFunc | Custom RNG between 0 (inclusive) and 1 (exclusive) | Function | Math.random() |
Customizing symbols
Download Node Js
Creating a custom strip is fairly easy. What is most important is that each symbol, whether an image or blank space, contains a vertical position that can be measured by calculating the symbol center (in pixels) from the strip top. A Photoshop example has been provided with this package for reference.
