Do not draw to a four-card inside straight -- one in which the missing card is in the middle rather than on either end -- unless it includes at least three high cards. A four-card open straight is one that has space open at either end to complete the hand; for example, a hand of 4-5-6-7 can use either a 3 at one end or an 8 at the other to complete the straight. An inside straight has space in the middle that must be filled to complete the hand; 4-6-7-8 needs a 5 to become a straight. Open straights give the player a better chance, with twice as many cards available to fill the straight.
Video poker machines started to become commercially viable following the integration of a monitor that looks like a TV screen. This allowed players to enjoy a 100 percent computerized game. The first ever computerized video poker game was developed in the mid-1970s. It was very primitive compared to modern day video poker games but it was the first ever computerized video poker machine that paved the way for other video poker games. The popularity of these machines started to skyrocket when a company called SIRCOMA (Si Redd’s Coin Machines) introduced the video poker game, Draw Poker, in 1979. SIRCOMA is now one of the biggest gaming developers for land-based and online casinos, going by the name IGT (International Game Technology).

So, if you find that game that returns 100.5%, you would be actually earning about 100.4% with our charts - not too bad. Not many charts get much closer than 0.1% because they would have to be extremely long and complicated to explain the subtle differences in rare hands.
