Stop calling it DICE.

[Kong Hey Pakboy]

I am amazed why it is called DICE gambling when it has nothing to with dice. RNG picks a number and thats all where is the dice in that. Normally  you have to choose in between 10000 numbers not like dice which has only six sides. Apart from that there is no visual animation corresponding to dice throw still there is picture of dice and it says ROLL, and I say LOL.

You may probably right and it's really sounds exaggerated that you need to choose between 1 and 10000 numbers in a dice game because commonly the number of sides of a dice is 6 sides and when you are playing a dice game in a casino they mostly used 2 dice.

Well, I have nothing to feel bad to do with it, by name this to dice. But if you literally think and compare it to the real dice you hold and you play physically it seems wrong so it's called dice because you can compare it to the dice because you can't predict what the number will appear when rolling this. This concept can only be replicated in the game of dice because of the mechanics of the game used by online or virtual casinos to make it popular with people playing virtual casinos, and I see no flaw in the way they use it because it's a tactic to get more people to play this simple game.

It's a good comment but when you play dice in real life you are absolutely free to roll as many dices you want.
Playing with 10 000 numbers as you say, is just virtually rolling 1 666 dices at a time.  
10 000 / 6 = 1 666

Try to search the complex term about dice not the easy one.

If you search about dice in google, the basic and common definition will show so that even average persons can understand what it is.
It's just like comparing the google definition into a book, there will be always a complex but precise definition on old books than google definitions.

Look on this Wikipedia definition, it says that the traditional dice is a cube, so meaning there are different kinds of dice too.

Dice may also have polyhedral or irregular shapes and may have faces marked with numerals or symbols instead of pips. Loaded dice are designed to favor some results over others for cheating or entertainment.

You do realise that almost every online game online is based on the concept of "RNG picks a number" and spits it out as your result right?

This is the same for blackjack, roulette, slots. How that RNG works out is different, but everything else is visualisation.

Shall we stop calling these blackjack/roulette, slots etc.?

Getting a digital visualisation of a 100,000-sided die shouldn't be a problem at all, if you ever become boss and insist on such things.

Now, if I put six 10-sided dice next to each other as a visualisation for you on a 0-100,000 "dice game", will you be satisfied?

No because you will get 1 000 000 numbers(000 000 to 999 999), not 100 000   Moreover OP was speaking about 10 000 numbers games like freebitcoin, not 100 000

There not only dice with six sides, there 12 dice, 8 dice, 24 dice and so on. Honest RNG is like a big, very big, n side dice and noone know for sure which "side" (or number) will fall. So you can imagine it as a big dice (so we naming it DICE). There no difference between 6 variant RNG and a simple DICE. They're the same

To be fair, I had the same question cause this game looks like a mixture of coin flip and Hi-Lo too.
There is 10-sided dice that has a form of pentagonal trapezohedron, so there are numbers from 0-9. When you play dice, you'll see that numbers are like:00.00 up to 99.99. So in this case imagine like you roll dice twice: 1. Rolled dice and got 3 and 4 (got 34.**) and then rolled another dice and got 7 and 3, so finally we got 34.73 by rolling dice twice.
I think this is the most appropriate explanation on question, why those games are called dice.
