At the time, the game paid a fixed cost of about 5 cents per spin. When the five trump cards were stopped in a row by a certain mechanism in the machine, the bar owner checked the poker genealogy and won prizes such as money, drinks, and cigars. It was done in a paid way. However, since this poker machine only held 10 cards per vertical reel, it used only 50 trump cards in total on 5 reels, excluding two cards of J♥ and 10♠, and as a result, 52 trump cards were used as a deck. There was a disadvantage that the exchange rate (RTP) was lower than that of general poker games.

In addition, since there was no cash slot or electricity connection as in the present, the shop owner directly received the money, and if the result of the game was an ace triple 온라인슬롯 genealogy, a drink, or a royal straight flush genealogy, a market price of 100. Dogs were paid as prizes. Nevertheless, this world's first slot machine, which was groundbreaking at the time in 1891, was a significant issue in New York, USA, and it was a must-have poker slot machine that bar owners wanted to have one to attract a lot of customers.

Another scenario when slots are removed, even if they are still working, is outdated. Examples of these types of cabinets are mechanical slots before digital cabinets. Mechanical slots are more of a novelty or decoration piece than a money maker for casinos.

To be clear, slots that accept coins or tokens are not removed from a casino immediately. These machines are upgraded with a bill acceptor to take paper money from the players. Rather than showering players with their winnings in coins, a printer provides you with tickets you can redeem for cash. On the other hand, slots that are incompatible with bill acceptors are removed from the gambling floor.

Why would casinos remove slots that do not accept paper bills? The answer is overhead reduction. It takes time, workforce, and counting equipment to tally all the coins and tokens from slot machines before the 2000s. There are also instances of coin jams among slot machines that bring down the daily revenue while increasing maintenance costs. It is also difficult for casinos to get accurate data on how much earnings they made from slots. With the introduction of a ticket system, casinos can do away with counting equipment and coin jams while receiving an accurate profit report on their slots.
