I have seen this concept when I was in my elementary days and it reminds me of the good old days. But I don't think casinos have it as a profitable game. It's interesting but it needs polishment if ever they will add it to gambling games. It can only be a commision-based game but couldn't be as profitable as other games since it has another concept. I don't think adults these days will also pick it over famous gambling games.
Maybe it is not as popular with typical gambling games. Online casinos are just following the trend because that would give profit to their business. If they will add all of the gambling games there is, there might be downsides on their end which is why only a few if there are any, gambling site/s offer this gane to the players. However, numerous gambling sutes are appearing each in everyday. Also, they are improving as well as the old ones wherein they are moving closer to modernity.
Before, gambling games would only consist of cardgames, slotmachine, dice, and such, but you can see gambling platforms having games which are in line with online games or games which are catchy or not evident with traditional gambling so hopefully your demanded game will soon be listed to many gambling site in order for more people to also experience it.
The casino companies that are interested to add this kind games add it and still programme it to make profit. Just the settings and breaks of the game. Each level has it own bet or the player bet through the level with a specific amount of money or each level has it own amount to pay and play. There is a way the casino companies can do that play can pay and play the game. The players can win loss.
And also casino companies are to add games that are favorable to gamblers to attract more customers on the site.
