Baccarat offers three main bets, and their edges are far apart. The banker bet keeps a little over one percent after its commission, the player bet slightly more, and the tie bet, despite its generous payout, keeps around fourteen percent. Side bets at every table game work the same way: big payouts on unusual hands, funded by an edge that dwarfs the one on the main wager. Staying with the main bets is the simplest way to keep the cost of a session down.
Roulette shows the effect of rules more plainly than any other game. A wheel with one green zero keeps about 2.7 percent of every bet, and adding a second zero raises that to about 5.3 percent without changing a single payout. Some tables with one zero return half of an even money bet when the ball lands on zero, which halves the edge on those bets. The layout looks alike in every version, so the number of zeros is worth checking before the first chip.
The expected cost of play is the edge applied to the total amount staked, and the pace of a game decides how fast that total grows. A fast online table can deal several times more rounds per hour than a busy physical one, so a small edge applied quickly can cost more than a larger edge applied slowly. Multiplying the average stake by the rounds per hour and by the edge gives a fair estimate of what an hour at a given table is likely to cost.
