The real edge of every game.
RTP (Return To Player) tells you how much a game gives back long term. The house edge is the opposite: how much it keeps. These numbers are mathematical, public and non-negotiable. Knowing which is high and which is low is the difference between betting with judgement and not.
Blackjack
Blackjack (estrategia basica)
RTP
99.50%
Edge
+0.50%
Volatility
Low
With basic strategy memorised (decision table by hand and dealer card), the edge drops to 0.5%. WITHOUT it, the edge rises easily to 3-5%. The strategy is public and free.
Blackjack Switch
RTP
99.13%
Edge
+0.87%
Volatility
Medium
Variant with two hands where you can swap the second card. Edge slightly worse than base blackjack with optimal strategy.
Video poker
Deuces Wild (full pay)
RTP
100.76%
Edge
-0.76%
Volatility
High
In its full-pay version the theoretical RTP is above 100%, meaning the player holds the mathematical edge. Almost impossible to find on current online casinos; reduced versions sit at 96-98% RTP.
Double Bonus Poker (10/7)
RTP
100.17%
Edge
-0.17%
Volatility
High
Full-pay 10/7 version of Double Bonus. Theoretical RTP above 100% (with optimal strategy). Almost impossible to find on Spanish casinos — paytables tend to be 9/7 or worse (RTP <99%).
Jacks or Better (9/6)
RTP
99.54%
Edge
+0.46%
Volatility
Medium
The most player-friendly video poker, in its 9/6 version (pays 9 for full house and 6 for flush). With optimal strategy, RTP is 99.54%. The 8/5 or 7/5 versions are a trap.
Joker Wild
RTP
98.60%
Edge
+1.40%
Volatility
Medium
Video poker with 53 cards (52 plus a Joker as wild). RTP 98.6% with optimal strategy in the Kings or Better version. Different strategy from Jacks or Better, harder to memorise.
Roulette
Ruleta francesa (con La Partage)
RTP
98.65%
Edge
+1.35%
Volatility
Medium
European wheel plus the La Partage rule: on even/odd, red/black and other even-money bets, if zero hits you recover half the stake. Edge drops to 1.35%. The best roulette you can find.
Ruleta europea
RTP
97.30%
Edge
+2.70%
Volatility
Medium
A single zero pocket (green). House edge is fixed at 2.7% on any bet. Strategy is irrelevant: long term you lose 2.7% of total stake.
Ruleta americana
RTP
94.74%
Edge
+5.26%
Volatility
Medium
Adds a 00 to the European wheel. The edge rises to 5.26%, almost double. If you have the choice, NEVER play the American version.
Baccarat
Baccarat (apuesta a Banker)
RTP
98.94%
Edge
+1.06%
Volatility
Low

Baccarat (apuesta a Player)
RTP
98.76%
Edge
+1.24%
Volatility
Low
Second-best baccarat bet after Banker. Pays 1:1 with no commission. Edge slightly worse than Banker (1.24% vs 1.06%) but emotionally simpler.
Dice / Craps
Craps (Pass Line + odds 5x)
RTP
99.67%
Edge
+0.33%
Volatility
Medium
With Pass Line plus maximum Free Odds (5x stake), the total edge drops to ~0.33%. It is the lowest-edge bet in the entire casino. Other Craps bets are far worse (Field 5.56%, Any 7 16.67%).
Craps - apuesta Field
RTP
94.44%
Edge
+5.56%
Volatility
High
The so-called simple Craps bet because you only need one roll. But the edge is 5.56% — 17 times worse than Pass Line with odds. Skip it.

Edge
+0.50%
Volatility
Low
Live streamed dealer. Same rules as base blackjack — edge ~0.5% with strategy. The side bets (Perfect Pairs, 21+3) carry a much worse edge (3-7%) — skip them.
