Number Slot Machine Javascript
- The Devil’s Number slot machine is a five-reel, 20-line game from Red Tiger Gaming. This company is behind some stunning-looking slot games including Wild Spartans and Lion Dance. But the visuals are a little more tame here, which is surprising, given the opportunity to fill the reels with animated demons and tortured souls.
- I am afraid that my javascript skill has a lot to do with the poor performance on mobile devices. I plan to release this slot machine program as an open source on gitHub soon in a few months. (I like to write a grunt JS script for the source code before releasing it to public.) About me I develop wordress theme most of the time.

At its 2000 opening, about 96% of these slot machines were coin-free, using vouchers as their preferred form of payout for wins over 200 credits. Wynn Las Vegas – Las Vegas, Nevada This $2.7 billion resort is home to 2,000 slot machines, which may seem like a startlingly small number when you consider the size of this place – then again.
Math
Math
is one of JavaScript's global or standard built-in objects, and can be used anywhere you can use JavaScript. It contains useful constants like π and Euler’s constant and functions such as floor()
, round()
, and ceil()
.
In this article, we'll look at examples of many of those functions. But first, let's learn more about the Math
object.
Example
The following example shows how to use the Math
object to write a function that calculates the area of a circle:
Math Max
Math.max()
is a function that returns the largest value from a list of numeric values passed as parameters. If a non-numeric value is passed as a parameter, Math.max()
will return NaN
.
An array of numeric values can be passed as a single parameter to Math.max()
using either spread (...)
or apply
. Either of these methods can, however, fail when the amount of array values gets too high.
Syntax
Parameters
Numbers, or limited array of numbers.
Return Value
The greatest of given numeric values, or NaN
if any given value is non-numeric.
Examples
Numbers As Parameters
Invalid Parameter
Array As Parameter, Using Spread(…)
Array As Parameter, Using Apply
Math Min
The Math.min() function returns the smallest of zero or more numbers.
You can pass it any number of arguments.
Math PI
Math.PI
is a static property of the Math object and is defined as the ratio of a circle’s circumference to its diameter. Pi is approximately 3.14149, and is often represented by the Greek letter π.

More Information:
Math Pow
Math.pow()
returns the value of a number to the power of another number.
Number Slot Machine Javascript Games
Syntax
Math.pow(base, exponent)
, where base
is the base number and exponent
is the number by which to raise the base
.
pow()
is a static method of Math
, therefore it is always called as Math.pow()
rather than as a method on another object.
Examples
Math Sqrt
The function Math.sqrt()
returns the square root of a number.
If a negative number is entered, NaN
is returned.
sqrt()
is a static method of Math
, therefore it is always called as Math.sqrt()
rather than as a method on another object.
Syntax
Math.sqrt(x)
, where x
is a number.
Examples
Math Trunc
Math.trunc()
is a method of the Math standard object that returns only the integer part of a given number by simply removing fractional units. This results in an overall rounding towards zero. Any input that is not a number will result in an output of NaN.
Careful: This method is an ECMAScript 2015 (ES6) feature and thus is not supported by older browsers.
Examples
Math Ceil
The Math.ceil()
is a method of the Math standard object that rounds a given number upwards to the next integer. Take note that for negative numbers this means that the number will get rounded “towards 0” instead of the number of greater absolute value (see examples).
Examples
Math Floor
Math.floor()
is a method of the Math standard object that rounds a given number downwards to the next integer. Take note that for negative numbers this means that the number will get rounded “away from 0” instead of to the number of smaller absolute value since Math.floor()
returns the largest integer less than or equal to the given number.
Examples
An application of math.floor: How to Create a JavaScript Slot Machine
For this exercise, we have to generate three random numbers using a specific formula and not the general one. Math.floor(Math.random() * (3 - 1 + 1)) + 1;

Example
Usage
Number Slot Machine Javascript W3schools
In mathematics, a number can be checked even or odd by checking the remainder of the division of the number by 2.
Note Do not confuse it with modulus%
does not work well with negative numbers.
