The classic 777 slot usually has three reels, but some variants have five. There are some games that have a single payline, while others have multiple paylines. Classic 777 slots use traditional slot machine symbols. Fruits include cherries, lemons, oranges, plums, watermelons, grapes, bells, bars, and the lucky number 7.

In most games, players select their bet size first and then adjust the cost per spin and the coin denomination. They place their bet, spin the reels, and the outcome depends on the combination of symbols. 

To win prizes, you must land matching symbols on the payline. There are different symbols with varying payouts, and the rarer symbols tend to pay out more. Some variants of Classic 777 slots may include special features to enhance gameplay. Combinations of symbols can trigger bonus rounds and mini-games, while wild symbols can substitute for other symbols.
