Declining Insurance: The Most Common Blackjack Mistake
The decision to take insurance in Blackjack, an optional side bet, is often driven by emotion rather than logic. This bet typically pays 2:1 if the dealer has Blackjack, but its house edge can be substantial. For instance, the Blackjack Surrender rule, which allows players to forfeit half their bet, improves RTP by approximately 0.08 percentage points. Accepting insurance, however, frequently increases the house advantage.
Consider the impact on your overall return. When insurance pays 2:1, it is a losing proposition against a dealer's Blackjack more often than not. This side bet effectively introduces a higher house edge compared to the main game. Unlike the beneficial effects of rules like Late Surrender (improving RTP by 0.08 p.p.), insurance often works against the player's long-term interests.
The consequence for players is a decrease in their potential return. While a successful insurance bet might seem like a win, its cost over time erodes your bankroll. This is especially true when compared to strategic decisions that positively influence the RTP. For example, the Baccarat Tie bet with a 9:1 payout, while still having a 4.84% house advantage, is more predictable than insurance's fluctuating odds.
37 vs. 38 Sectors: What the Double Zero Costs
The difference between European and American Roulette wheels, specifically the presence of a double zero, significantly impacts the house edge. A European Roulette wheel has 37 sectors (numbers 1-36 plus a single 0), resulting in a 2.70% house advantage. An American Roulette wheel adds a '00' sector, bringing the total to 38 sectors.
This additional sector on the American wheel directly doubles the house's advantage on all bets. For instance, the house edge on American Roulette stands at 5.26%, whereas on European Roulette it is 2.70%. This means that for every €100 wagered on American Roulette, the casino expects to retain €5.26, compared to €2.70 on its European counterpart.
The cost to the player is a lower RTP on all wagers. On American Roulette, the RTP is 94.74%, while on European Roulette, it is 97.30%. This disparity is substantial over many spins, making the single-zero wheel the demonstrably more favorable option for players seeking better odds on straight, split, or corner bets.
Straight, Split, and Corner: Three Terms Briefly Explained
In Roulette, these terms refer to specific types of inside bets, each with a different payout structure and probability. A 'Straight' bet is a wager on a single number, offering the highest payout. For example, a Straight bet on European Roulette pays 35:1.
A 'Split' bet covers two adjacent numbers on the betting layout, paying 17:1. A 'Corner' bet, also known as a 'Square' bet, covers four numbers that meet at a corner, paying 8:1. These bets are placed on the inner section of the Roulette layout.
The house edge remains consistent across all these inside bets on a standard European wheel (2.70%). On an American wheel, however, the introduction of the double zero increases this edge to 5.26% for Straight, Split, and Corner bets alike, significantly reducing the RTP for players.
Pass Line in Craps: Process in Four Steps
The Pass Line bet in Craps is a fundamental wager made on the Come Out roll. This initial roll determines the game's progression. If a 7 or 11 is rolled, the Pass Line bet wins immediately. If a 2, 3, or 12 is rolled, the Pass Line bet loses, with 12 often resulting in a 'push' (return of stake).
Should any other number (4, 5, 6, 8, 9, or 10) be rolled, that number becomes the 'point'. The game then continues with subsequent rolls. The objective for the Pass Line bettor is for the point number to be rolled again before a 7 appears.
The RTP for the Pass Line bet, which pays 1:1, is 98.64%, with a house advantage of 1.36%. This is slightly more favorable than the Don't Pass bet, which also pays 1:1 but has a push on a roll of 12, making it marginally better for the player in certain scenarios.
La Partage applies only to even money bets
The 'La Partage' rule in French Roulette is a player-friendly provision that significantly enhances the RTP on specific wagers. This rule applies exclusively to even-money bets, which include Red/Black, Odd/Even, and High/Low (1-18/19-36). When the ball lands on zero during a spin, half of the player's stake on these even-money bets is returned.
This mechanism directly reduces the house edge on these bets. For example, on European Roulette with La Partage, the RTP for even-money bets rises to 98.65%, lowering the house advantage to 1.35%. Without La Partage, the standard RTP for these bets on a European wheel is 97.30%, with a 2.70% house edge.
It is crucial to understand that La Partage does not extend to inside bets such as Straight, Split, or Corner bets. These wagers retain the standard house edge of 2.70% on a European wheel, even when La Partage is in effect. Therefore, players should strategically employ La Partage only on its designated even-money options.

Dozen 2:1: Twelve Numbers, One Third Coverage
The Dozen bet covers twelve numbers on the roulette table, representing one third of the playable field. This bet pays 2:1, meaning a €10 stake returns €20 in winnings plus the original stake. This bet has a house edge of 2.70% on French Roulette (without La Partage on inside bets) and 5.26% on American Roulette.
When playing French Roulette with a 2.70% house edge, a €100 bet per spin across all dozens would theoretically result in a €2.70 loss over the long term. French Roulette's 37 sectors offer a better RTP of 97.30% compared to American Roulette's 38 sectors and 94.74% RTP.
A €10 wager on a dozen in French Roulette offers a payout of €20 if successful, compared to €35 for a straight bet. While offering a lower potential return than a straight bet, it covers a larger portion of the wheel, impacting the frequency of wins.
Multihand Blackjack with Up to 5 Hands
Multihand Blackjack allows players to engage with up to five hands simultaneously, offering a dynamic gameplay experience. Each hand operates independently, allowing for varied betting strategies across the multiple concurrent games. This format can increase the overall wagering volume per round.
In a game featuring Blackjack with a 6:5 payout for a blackjack, the house edge stands at 1.85%, a significant increase from the traditional 3:2 payout. Playing with five hands means this edge is applied to each hand played, potentially amplifying losses if not managed carefully.
A player choosing to bet €10 on each of five hands in a 6:5 Blackjack game could wager a total of €50 per round. If a blackjack occurs on one hand, the payout would be €12, whereas a 3:2 payout would have yielded €15, illustrating the impact of rule variations.
Read Statistics of Last 500 Rounds Correctly
Observing the last 500 rounds of Baccarat can provide insight into recent trends, though it does not alter inherent probabilities. The Banker bet, with a 5% commission and an RTP of 98.94%, is generally considered the strongest wager. This edge is calculated after the commission is applied.
In Baccarat, the Banker bet has a house edge of 1.06% over 8 decks, while the Player bet carries a slightly higher edge of 1.24% due to the absence of commission. Both bets have a standard deviation of approximately 0.95, indicating relatively stable outcomes per round.
A Tie bet in Baccarat, paying 8:1, has a significantly higher house edge of 14.36%, making it a less favourable option compared to the Banker or Player bets. Even with an improved payout of 9:1, the Tie bet's RTP remains at 95.16%.
Three Roulette Variants, Three House Edges Compared
American Roulette, with its double zero (00), presents a house edge of 5.26%. This variant features 38 sectors on the wheel, encompassing numbers 1-36, 0, and 00, with standard payout ratios.
French Roulette offers a more favourable RTP of 97.30% and a house edge of 2.70% due to its single zero (0). However, when the La Partage rule is not applied to inside bets, the house edge remains at this European level for all wagers.
A comparison shows that European Roulette (RTP 97.30%, house edge 2.70%) is superior to American Roulette (RTP 94.74%, house edge 5.26%) for all bet types. The presence of the extra '00' sector in American Roulette effectively doubles the casino's advantage.
Sic Bo Pays from 1:1 to 180:1
Sic Bo offers a wide range of payouts, from a modest 1:1 for single number wins to an impressive 180:1 for specific triple combinations. The game's betting options allow players to choose stakes that align with their risk tolerance.
The 'Single Number' bet in Sic Bo provides the lowest house edge, starting at 7.87%, making it the most statistically favourable special bet available. Conversely, the 'Specific Double' bet carries the highest house edge at 18.52%, representing a significantly greater disadvantage for the player.
A wager on 'Any Triple' in Sic Bo offers a payout of 30:1, with a corresponding house edge of 13.89%. This payout structure reflects the lower probability of this outcome occurring compared to simpler bets like 'Single Number'.
6 Decks vs. 8 Decks in House Edge
The Blackjack game variation utilizing six decks exhibits a house edge of 1.85%. This figure is derived from the casino's advantage when the payout for a blackjack is set at 6:5, a common modification from the standard 3:2 payout.
Compared to Blackjack played with eight decks, where the house edge is 1.24% with a 5% commission on Banker wins and a 1:1 payout for Player, the six-deck game with a 6:5 payout presents a notably higher disadvantage. This difference of 0.61 percentage points significantly impacts player returns over time.
For a player betting 10 EUR on a six-deck game with a 6:5 payout, a blackjack would yield 12 EUR. In contrast, a standard 3:2 payout on the same 10 EUR bet would result in 15 EUR, illustrating the financial consequence of this rule variation on player winnings.
When is Splitting Aces and Eights Sensible?
Splitting Aces in Blackjack, as part of a classic ruleset, is a strategy that can significantly alter the player's advantage. While specific RTP figures for this rule are not detailed, the act of splitting is generally beneficial as it allows for potentially two strong starting hands.
Conversely, splitting eights in Blackjack is often recommended due to the inherent weakness of a starting hand totaling 16. By splitting, the player aims to improve their chances of forming two hands with a higher likelihood of winning against the dealer's upcard.
The impact of rules like 'Late Surrender' on Blackjack RTP is noted as a modifier, potentially improving it by 0.08 percentage points. This rule allows players to forfeit half their bet after the dealer checks for blackjack, a distinct advantage not directly tied to splitting specific cards but to overall game strategy.
37 vs. 38 Sectors: One Zero Difference
European Roulette, featuring 37 sectors including a single zero, offers a house edge of 2.70%. This is calculated based on payouts designed for 36 sectors, meaning every bet type, without exception, carries this inherent advantage for the casino.
American Roulette, with its 38 sectors due to the addition of a double zero (00), doubles the casino's advantage. Despite having the same payout structure as European Roulette, the extra sector increases the house edge to 5.26%.
For instance, a 'Straight' bet on European Roulette pays 35:1, while on American Roulette, the odds remain the same. The increased number of sectors on the American wheel, from 37 to 38, directly impacts the probability of winning any given bet.
Video Poker 9/6: What the Two Numbers Mean
The '9/6' designation in Jacks or Better Video Poker refers to the payout ratios for specific hands. Specifically, a Full House pays 9 coins for every coin wagered, and a Flush pays 6 coins for every coin wagered, assuming a one-coin bet.
This particular 'Full Pay' version of Jacks or Better boasts a Return to Player (RTP) of 99.54%, with a corresponding house edge of 0.46%. Optimal strategy is crucial for achieving this RTP, especially when placing the maximum bet of five coins for the Royal Flush bonus.
The standard deviation for this video poker variant is 4.42, indicating the level of variability in results. A Royal Flush, when playing the maximum five coins, offers a payout of 4000 coins, significantly higher than the 800 coins paid for a Royal Flush with fewer coins wagered.
100 EUR bet, 50 rounds: the expected value
When placing a 100 EUR bet in a game with a 98.64% RTP, such as Craps 'Don't Pass', the expected loss over 50 rounds can be calculated. The house edge of 1.36% indicates the average percentage the casino expects to retain from all wagers over the long term.
For a 100 EUR bet per round over 50 rounds, the total wagered amount is 5,000 EUR. With a 1.36% house edge, the expected loss across these 50 rounds would be approximately 68 EUR (5,000 EUR * 0.0136).
This expected value represents a theoretical long-run average, meaning actual results in 50 rounds can vary significantly. For example, French Roulette with La Partage rule, offering a 1.35% house edge, would yield a slightly lower expected loss of approximately 67.50 EUR on the same 5,000 EUR wagered.
