Are you a pro gamer? A game enthusiast? A geek? If you are, you might have observed the use of random numbers in almost every game. A dice game is one of the finest examples of random number generation. Suppose you are playing this game with a machine online. You roll the dice and get any number between 1 and 6. Similarly, even the machines get their own random numbers. The numbers that we see on the screen while playing games (on the dice) are numbers that are generated randomly. How do these games generate random numbers continuously, you may ask?
An algorithm called the Random Number Generator (RNG) is used to produce numbers randomly in these games. RNG finds its significance in modern video games to determine which rare items you collect or the obstacles you come across.

It is also used in traditional games like poker, where the numbers decide the winner. Crafting working code in Python is crucial when it comes to RNG models. To enhance that, CasinoAlphaNZ’s analysis shows just how crucial it is to ensure flawless implementation. Even the tiniest error in the code can have catastrophic consequences, potentially reducing the chances of winning in games reliant on the RNG to a dismal zero. The implications are far worse for the establishments that run flawed and unmoderated random number generators. As these companies could face legal action if their flawed RNG code leads to skewed outcomes.
This underscores the vital role of rigorous testing, thorough debugging, and adherence to best practices in RNG coding to maintain both fairness and integrity within the gaming industry.
Let us learn more about these random number generators and the important Python module behind the Random Number Generators.
Exploring the Random Module
The random module is the Python module behind the random number generator(RNG) algorithm. Most of the RNG algorithms use the random module to generate pseudo-random numbers.
The random module can be imported into our environment with the help of this simple line of code.
import random
When using the random module for the random number generators, we need to be cautious about what functions to use and know the result of the usage.
To learn more about the functions of the random module, consider reading this post.
Let me simplify for you. The table below consists of the functions of the random module we can use to generate random numbers.
| Function | Syntax | Description |
| seed | random.seed() | Used to generate the same set of random numbers each time the algorithm is executed |
| randrange | random.randrange(start,stop[,step]) | Given a starting number(start), and the last number(stop), this function is used to generate random numbers with the specified increment(step) |
| randint | random.randint(a,b) | The randint function is used to produce a random integer in the range of a,b |
RNG – Generating Random Numbers
I hope you have understood the significance of RNGs and what they use at the foundational level, let us try to create a random number generator that generates random numbers within the given range.
We are going to use Tkinter, a GUI tool of Python to create an interface of the Random Number Generator algorithm. Follow the code given below.
import tkinter as tk
import random
interface = tk.Tk()
interface.title("Random Number Generator")
def genrandnum():
minval = int(minentry.get())
maxval = int(maxentry.get())
randnum = random.randint(minval, maxval)
res.config(text=f"Random Number: {randnum}")
minlabel = tk.Label(interface, text="Minimum Value:")
minlabel.pack()
minentry = tk.Entry(interface)
minentry.pack()
maxlabel = tk.Label(interface, text="Maximum Value:")
maxlabel.pack()
maxentry = tk.Entry(interface)
maxentry.pack()
res = tk.Label(interface, text="", pady=10)
res.pack()
genbutton = tk.Button(interface, text="Generate Random Number", command=genrandnum)
genbutton.pack()
interface.mainloop()
Lines 1 through 4 – We import the tkinter and random modules. Tkinter needs a window to display the output so we are creating one and also giving it a title.
Lines 5 through 9 – Here comes the main function- we take two values from the user (a minimum and a maximum value), pass them to the randint function, and generate a random number.
The next few lines are used to label the user’s inputs and create a button to generate random numbers. Here is a screengrab of the Tkinter window.
We also have a demo to help you use the RNG!
Wrap Up
That’s a wrap! I hope this tutorial was helpful in learning about the random number generator algorithms and their applications in various video games. In this comprehensive tutorial, we have observed various use cases of random numbers with the help of a few examples and explored the random module to understand the generation of random numbers.
We used this prior knowledge to develop RNG and made it interactive using Tkinter.
