Game strategy terms and concepts

Blackjack strategies

Basic/Perfect Blackjack strategy Basic blackjack strategy rests on the mathematical fact that the odds of beating the dealer vary depending on the initial cards that each of you are holding. Essentially, it is just a set of rules that makes it easier to know how to respond to each of the blackjack hands you get, accounting for the dealer’s up card. When you learn basic blackjack strategy, you’ll have a set of tables that you will need to learn. They lay out the action you should take in each possible scenario. While there are 34 possible starting hands, there are only a few different responses you can have to them.

As the name suggests, basic strategy is only the beginning. The perfect blackjack strategy builds on the concepts to create a more refined set of instructions. It varies depending on the number of decks in the shoe and whether the dealer is instructed to stand or hit on soft 17. The more extensive list of combinations makes perfect blackjack harder to learn. Still, if you can do it correctly, it will help reduce the house edge below the 0.5% achievable with basic strategy.

Bet spread - The ratio of maximum to minimum bet (Blackjack).

Double Down - Doubling down means increasing your wager by two if you notice you have a strong hand and the dealer has a weak up card.

Hard/Soft Hands - A soft hand contains an ace since you can be more flexible with changing its value from 1 to 11 (and vice versa). Hard hands, on the other hand, don’t contain an ace.

Hit/Stand - Hitting means asking for another card from the dealer. On the other hand, standing means sticking with your cards. Generally, you hit when you have a weak hand, though exactly when also depends on what the dealer has.

Optimal strategy - A set of plays designed to make the player get the best returns from a casino game, mostly used in video poker and blackjack.

Perfect blackjack - The best possible hand in blackjack, consisting of an ace and a card with a value of 10.

Split - The option to bet your original amount again, splitting your two cards into two hands. While you should always split AA and 88, you should always stand on 1010.

Roulette strategies

Note: All games have a casino RTP or house edge, and roulette is no exception. These strategies don’t actually change this because the odds of a win are always the same. In theory, some of these strategies could help you offset losses by making larger and larger bets, but the table limits prevent this. You should see strategies as a fun way to add structure to your game, not as a way to make guaranteed wins.

Martingale - A strategy which says you should increase your bet after each loss by doubling and adding one unit.

Reverse Martingale The same as Martingale, but you double your wagers for wins and half them after each loss. It has the same pros and cons as it will hit the table limit in just a few rounds.

Labouchère - A more complex numbers-based strategy: To use it, you need to choose a sequence of numbers (they can be anything you want) and make a bet that is the sum of the first and last numbers in it. If you win, you remove the first and last positions from the sequence and start again, if you lose, you add the wager size to the end of the sequence.

Fibonacci - A Fibonacci sequence is one that spirals exponentially larger by adding the last two numbers in the sequence together. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233. In roulette, the Fibonacci strategy involves increasing your wagers in a Fibonacci sequence.

D’Alembert- With this strategy, if you start out with a €1 bet and lose, you’d increase it to €2, then €3, €4, and €5. If you then won, you’d just subtract €1, moving back down to €4, and then €3.

Inside bets - Bets on the inside section of the roulette layout, where the numbers are printed. These bets cover only individual numbers and small groups of numbers and pay out at relatively high odds.

Outside bets - Bets made on the outside part of the roulette table layout, generally covering large sections of the roulette wheel and paying out at lower odds. Many are even money bets, such as red/black or odd/even.
