What is a ‘Sequence’?
In casino games which use playing cards, a ‘sequence’ is a run of consecutive cards. The term usually applies to a ‘straight’ – a five card hand in which a series of numbers is present, such as 2-3-4-5-6 or 8-9-10-J-Q. ‘Sequence’ can also refer to any pattern of events in a gambling game, such as with a sequence of free slot spins or a sequence of bingo numbers.
The term sequence means ‘one thing after another’, and it is usually applied to numbers or to events that happen in succession. Sequences are very important in the gambling industry, where almost all games are based on mathematical systems. ‘Sequence’ has different meanings depending on the game being played.
For example, a ‘sequence’ in roulette means a string of numbers which have been called recently and which are usually displayed at the table. In fixed odds betting, a ‘sequence’ of bets is a string of consecutive bets which may or may not form part of an accumulator. In slots play, spins often fall in ‘sequences’, especially in bonus rounds.
In poker, ‘sequence’ refers to a ‘straight’, which is a five-card hand containing a set of consecutive numbers. The card values are usually ranked from 2-A, so the lowest straight available is a 2-3-4-5-6 hand and the highest is a 10-J-Q-K-A hand (‘ace high straight’ when offsuit, and a ‘royal flush‘ when suited). The ‘sequence’ can also apply to reversed number strings in lowball games – when the rules are flipped, A-2-3-4-5 becomes the most desirable straight to hold (also known as a ‘wheel’ or a ‘wheel hand’). A player might say that they held a sequence, drew a sequence or that they sought to make a sequence, and even that they won the pot through a sequence.
