Games, rules and the arithmetic behind them

Section

Rules Desk

Short entries stating one published rule convention each, with the arithmetic that follows from it.

Rule entry

Dealer stands on soft seventeen

A single line on the felt, and one of the larger arithmetic differences between two otherwise identical blackjack tables.

A soft hand is one containing an ace counted as eleven. A soft seventeen is therefore an ace with a six, or an ace with cards totalling six, and it cannot be broken by drawing one more card.

Rule entry

House edge is arithmetic, not luck

The edge on a wheel is a property of the gap between the number of pockets and the payout offered on hitting one.

House edge is not a force acting on a session and it is not a description of how a night went. It is a subtraction, and it can be carried out in a line.

Standing entries

Conventions in brief

  • Blackjack

    The felt states whether the dealer stands or draws on a soft seventeen; the two are different games.

  • Roulette

    A single-zero ring holds thirty-seven pockets and a double-zero ring holds thirty-eight, at the same payout.

  • Baccarat

    Banker wins carry a stated commission, printed with the rest of the table terms.

  • Blackjack

    Surrender, where a table offers it at all, returns half a wager against the dealer’s up card.

  • Reel games

    A paytable states combinations and multipliers; the reel strips that set their frequency are not published.

  • Craps

    The puck records the round: dark face up for a come-out roll, light face up on an established point.
