About the suggested ideas, I doubt them, because there’s always a chance to add something unique. But about your own brand-new strategy, short answer, no. I don’t think it’s even possible to use strategies in casinos, where everything depends on randomness and algorithms. But playing in rolling slots app, I came up with some personal rules that help me control myself and partly the game process. Things like bankroll management, number and size of bets, emotional state, etc.
