Video Slot Machines

The video slot machine is a more recent innovation, with no moving parts at all – instead a graphical representation of one appears on screen. Since the player is essentially playing a computer game, the manufacturers are able to offer more interactive elements, such as advanced bonus games and advanced video graphics.

In addition, because there are no mechanical constraints on the design of video slot machines, most display five reels rather than three. This greatly expands the number of possibilities: a machine can have 50 or more symbols on a reel, giving odds as high as 300 million to 1 against – enough for even the largest jackpot. As there are so many combinations given by five reels, the manufacturers do not need to weight the payout symbols although some may still do so. Instead, higher paying symbols will typically appear only once or twice on each reel, while more common symbols, earning a more frequent payout, will appear many times.

Video slot machines typically encourage the player to play multiple 'lines', so rather than simply taking the middle of the three symbols displayed on each reel, a line could go from top left to bottom right, or any of the other patterns specified by the manufacturer. As each symbol is equally likely, there is no difficulty for the manufacturer in allowing the player to take any or all of the possible lines on offer – the long-term return to player will be the same. The difference for the player is that the more lines he plays the more likely he is to get paid on a given spin – though of course he is betting more in the first place.

To avoid the feeling that the player's money is simply ebbing away whereas a payout of 100 credits on a single line machine would be 100 bets, and the player would feel they had made a substantial win, on a 20 line machine, it would only be 5 bets and would not seem significant, manufacturers commonly offer bonus games, which can return many times their bet. The player is encouraged to keep playing to reach the bonus: even if he is losing, the bonus game could allow him to win back his losses.

Poker Texas Holdem Hi-Low Split

Texas Holdem Hi-Low Split

Texas Hold-em is a community card poker game that is played with a standard 52-card deck. The game starts to the left of the dealer button. The blind bet(s) are made from the position(s) left of the dealer button and are forced bets which must be made before the cards are dealt.

Two cards (hole cards) are dealt to each player, one at a time, face down, in rotation. This is followed by the first round of betting. A player may check, bet, call, raise or fold. Three cards (the flop) are then dealt face up in the middle of the table as community cards (board cards) and the second round of betting occurs. The fourth community card is dealt face up (the turn), followed by the third round of betting. The final community card (the river) is dealt face up and followed by the fourth (final) round of betting.

At showdown, a player must use a combination of exactly two hole cards in their hand and three of the five community cards from the board to determine their best five-card high and five-card low poker hand. The highest and qualifying lowest (8 or better) five-card poker hands split the pot. If no low hand qualifies with an 8 or better, the highest five-card poker hand wins the entire pot. In the event of a tie, the portion of the pot that was tied will be equally split.
