The image below makes me flash back then days when I do use to play mortal Kombat game.
However, I am looking 15-20 kicks, as most time when playing with two users it takes more than but, for system were it's automated it may be less than that as the system could looks for the easiest way of reducing the kick to lesser counts.
Note: this comment is based on my experience on the said game mentioned above.
Who wouldn't? Some of us here grow on that era wherein that games are part of us growing up. And we have seen movies about this kind of games so it's sort of nostalgia to see this in a casino like Spinly.
And then is why this casino might separates itself from the rest. Their vibe is different, retro style UI and feel. And again, most of the gamblers can relate to it as we grow on that era. So it's a good design and smart one by the people behind this casino. It's like they are giving gamblers a interaction without actually doing it.
