non-existing? if we mean the same ads (mainly the cartoonish knight with bluish-black hair, though I've seen a caveman variant from another game) the game does exist. I played it about ten years ago, back when their ads were still the puzzles you supposedly need an IQ of 300 to solve. (kudos for keeping up with the times, I suppose.) /s it's a gacha money-pump, but I don't think the developers are strictly guilty of false advertising: from memory, the game does include one minigame or another reproducing the ad's loop.
