Most slot machines forget you the moment you leave. A few keep something visible that the next player inherits, and those are the only machines where advantage play exists. The spin is still random. What changes is how much the next spin is worth, because a prize or feature sits closer than it does at a reset.
1. A counter that must trigger before a ceiling
The machine shows a number that climbs as symbols land and guarantees a feature before it reaches a stated maximum. Phoenix Link is an example: a phoenix counter must trigger Hold & Spin before it reaches 1888, and after a trigger it resets to a random lower value. The higher the counter when you sit down, the fewer spins you pay for before the forced trigger. The mechanics are in must-hit-by progressives explained.
2. Meters that climb with play
Some games run several meters at once and only some of them build. Buffalo Power Pay has Major and Mega free-game meters that grow, while its Mini and Minor are fixed and never change, so knowing which meter counts is half the skill. Buffalo Diamond uses green, blue and purple meters that advance at different rates depending on the bet level. Where a game does this, the bet level is part of the reading.
3. Coins banked toward a feature
5 Coin Frenzy shows how many coins have been collected toward Frenzy Mode on the bet pad, not on the reels. A machine sitting one coin short is worth more than a machine at zero, and a machine left mid-feature still has spins in it. The state is a small integer you can read in a second.
4. A board that grows as it is played
Buffalo Ascension adds to its ways-to-win count as it is played, and the larger count stays for the next player. A big board is stored value: you get it immediately without paying the spins that built it.
5. Feature meters built by earlier spins
Rich Little Piggies has three feature meters that build through landed coins: more free games, bigger prizes, extra wilds. The features trigger randomly, so a bigger meter is a bigger potential payout, not a more likely one. That distinction is the one beginners most often get wrong.
What a display can't tell you
Seeing state does not mean playing is a good idea. Whether a given reading is worth a spin depends on the denomination, the bet level and the machine's payback setting, which is why the exact thresholds live in the guides and the calculators, not in a rule of thumb. Even a favorable reading is an average over many sessions. Set a loss limit before you sit down (see slot bankroll and variance) and leave when the reading drops.

Frequently asked questions
Which slot machines carry state from one player to the next?
Machines that keep something visible between players: a counter that must trigger a feature before it reaches a ceiling, colored meters that climb with play, coins banked toward a feature, a ways-to-win board that grows as it is played, or feature meters built up by earlier spins. Most slot machines carry none of these.
Does a machine carrying state mean it is likely to win?
No. The spin is still random. State changes how much a spin is worth, because the prize or feature is closer than at a reset, so the average cost of playing falls. Any single session can still lose, and you must be 21 or older to play.
How do I tell whether a machine has state?
Look at the display, not the reels: a counter, a meter, a coin count or a number that persists. If the machine shows nothing that carries over, treat it as an ordinary slot, where past spins change nothing.
