Things to keep in mind to improve your chances of winning
Monster Hi-Lo relies entirely on card prediction. If a mid-range card (such as 7) appears, the next card has a slightly higher chance of being Hi than Lo. If a very low card (such as 2 or 3) appears, the next card is more likely to be Hi.
Keep in mind, however, that each card is drawn independently and the result of a previous round does not affect the next round. So always bet responsibly and stay within your means.
