Craps, whether online or offline, is a game of chance. This applies even more accurately when played online because players can not control the strength with which they roll the dice. That said, one may try to come up with a playing strategy by choosing where they get into the game.
Forgoing the shooter role and waiting to bet when the game has already established a point is always a great strategy to bet with. It allows the player to avoid the mandatory bet that a shooter has to place, which in turn means that the winning edge is increased.
Again, players may opt to bet on a series of rolls rather than a single roll. Since all faces of the dice pair have an equal chance of coming up, betting on a series of rolls means that the desired results have a higher chance of occurring. However, this results in a lower payout because of the smaller odds.
Betting on number ranges is also more rewarding than placing a wager on a fixed outcome. This is where players bet on an outcome of, say, a total of 'between four and seven' or 'above five.' With such a risk spread, the probability of losses diminishes.
