Electronic slots often malfunction. The amount that is displayed is lower than the actual amount. While this usually goes unnoticed, it can result in disputes between players and casinos. In 2010 in Colorado, two casinos reported inaccurate jackpots. The Colorado Gaming Commission investigated the machines and discovered software errors, which lowered the actual jackpot to a lower number. A payout percentage under a hundred is a win for the casino. However, there are some situations when a payout percentage can be changed without physical access to the slot machine.

The Slot in hockey is a rectangular area that extends toward the blue line. It is also used for the fourth position in the flying display. This type of slot is an invention of the Intel Corporation. The first slot was introduced in 1997. The next year, AMD came out with the Slot A version. However, the two slots were not compatible. Then, Intel released Slot 2 with a larger slot for the Pentium II processor. However, despite being a distinctly different style, slots are not commonly found on new computers. Instead, sockets are the more popular choice.
