Honestly i feel the same way because I'm fan of sports gambling and at the same time is slots, when i try to play prediction gambling that's the time that the opponent makes a gameplay and manage to win the game unlike the highest potential of winning the game, and base on the slot games theres no prediction right there so more easier to play the hardest prediction is an algorithm game or an actual game
Well you cannot predict the outcome of a slots. Even if you break the algorithm of it, you will find that the result is random. Though I thinking if there is anyone who happen to break a slots algorithm and be able to sync with it resulting in a win for the overall gambling session, I bet there is no one had done that.
