Slot machines are devices that are operated using a lever or button to spin the reels and award credits if certain symbols line up. The symbols vary depending on the theme, but classics often include fruit, lucky sevens, and bells. Most have a specific theme, and bonus features are usually aligned with this theme. Some slot machines have more than one theme. To play them more efficiently, check out the pay tables on the game’s face.
The word “slot” is a contraction of the French slit. It is used to describe an interior opening of a copy desk where the chief copy editor sits. Slot is also used to describe the opening between the primaries of certain birds that maintain smooth airflow over their wings. It is an idiom that can be applied to either a guy or a girl. It is an apt description of many urban teenagers today.
The payback percentage of a slot machine is set by the manufacturer when the game is manufactured. To change the payout percentage, the manufacturer has to physically swap the slot machine’s software. Because the payout percentage is stored on an EPROM (electronic memory), this process is labor intensive and in some jurisdictions, it requires the presence of Gaming Control Board officials. But it’s not impossible to change the payout percentage of a slot machine.
