Table Games at Elon: The Small Rules That Move the Odds
Roulette, blackjack, baccarat and casino poker have fixed, well-known maths, which makes them the easiest games in any lobby to evaluate yourself. The trick is that tables carrying the same name can run different rules, and those differences change the house edge more than any betting system ever could. This page lists the variants to look for, whether you play software tables or the live versions covered in the live casino guide.
Roulette: count the zeros
A single-zero wheel has 37 pockets; a wheel with zero and double zero has 38. Because winning bets pay as if zeros did not exist, the extra pocket is pure house edge: about 2.70% on a single-zero wheel and about 5.26% with a double zero. Some single-zero tables add a rule that returns half of an even-money bet, or holds it for the next spin, when zero lands — which reduces the edge on those bets. Check the table name and the rules screen; the wheel layout is usually visible before you bet.
Blackjack: the rules on the felt
| Rule | Better for the player | Worse for the player |
|---|---|---|
| Payout for a natural | 3:2 | 6:5 (adds about 1.4 points to the edge) |
| Dealer on soft 17 | Stands | Hits |
| Doubling | On any two cards, including after a split | Only on certain totals |
| Number of decks | Fewer | More |
Basic strategy — the mathematically best action for each hand against each dealer card — is published widely and can be learned from a chart. Side bets are separate wagers with their own, usually much higher, house edge; read their payout table before adding them.
Baccarat: commission and ties
Baccarat leaves you three choices: Player, Banker or Tie. Banker wins slightly more often, which is why a commission (traditionally 5%) is taken from Banker wins; "no-commission" tables replace that with a reduced payout on certain Banker wins instead. The Tie bet pays generously but carries a far larger house edge than the two main bets. Check which version the table uses and what the Tie pays.
Casino poker against the dealer
In casino hold'em-style and stud-style games you play your hand against the dealer, not other players. Look for three rules: whether the dealer must "qualify" with a minimum hand for your raise to be paid, how the ante is paid when the dealer does not qualify, and the bonus paytable for strong hands. Correct play is a simple fold-or-raise decision that can be learned from a strategy chart.
Software tables or live tables?
Software tables use a random number generator, have no round timer and often allow lower stakes, which suits learning. Live tables use real equipment on camera and run on a fixed clock. The maths of a given rule set is the same either way; what differs is the pace and the minimum stake. Whichever you choose, the checks are the same: the casino's licence in the regulator's register, a named studio and a complete rules screen.
Responsible play at the tables
No betting system — doubling after losses, fixed progressions or pattern tracking — changes the house edge; progressions only make losses larger and faster. Use a flat stake that fits your budget, decide a time limit in advance and stop when either limit is reached. The responsible gambling page covers deposit limits, time-outs and free support.
