Payline, wild, scatter, free spins — and the terms most often used loosely.

Most slot vocabulary is English borrowed into Thai and passed along, and a few terms get used loosely enough to become misconceptions. This page collects the ones you will actually meet.

TermWhat it means
ReelOne vertical strip of symbols. Classic games have three; video slots usually five.
PaylineA path across the reels that a winning combination has to follow. Some games have one, some hundreds.
WildA symbol that stands in for others to complete a combination. What it can replace is stated in the paytable.
ScatterA symbol that counts wherever it lands rather than along a payline, and usually triggers a bonus.
Free spinsRounds awarded by a game feature. They are part of the game, not a promotion, and carry the game's own conditions.
Bonus roundA separate screen or mode entered when a condition is met.
StakeWhat you commit to a single round. The only figure you set yourself.
PaytableThe game's own information screen: which combinations pay and what the specials do.
VolatilityA descriptive term for how a game tends to pay — smaller and more often, or larger and more rarely. It is a description, never a prediction.
RNGThe random number generator that decides each round independently of the last.

Terms people use loosely

"Pays easily" — conversational, not a measurable property of a game. The nearest real concept is volatility, which describes a pattern of paying and says nothing about the next round.

"A good time of day" — technically nothing. Time is not an input to the calculation.

"A system" — when rounds are independent, the order you press or the way you size a stake cannot change an outcome.

This site publishes no volatility rating or payout figure for any game, because no such data has been confirmed for publication. The game's own information screen is the reliable source.
