Sometimes I play on more higher odds like 9900x because I know we have very smart chance of win, from my opinion best way to play on dice game to go with 2x, because it is all about our luck if we have our day than it is easy to make profit with such odds.
Smart chance to win using that 9999x? Are you joking? You can win it but you really need a lot of bankroll to spend, and although if you can win it you still cany recover what you loss before unless you dare to play using martingale may be 1.1 or 1.2 on loss until hit it may be you can get huge profit
