How to play
This is the slot machine in its oldest shape: three reels, one window, one payline across the middle. Each reel is a strip of 32 stops carrying sevens, triple bars, double bars, single bars, cherries and a lot of blank space. You start with 1,000 credits.
Pick a bet of 1, 2, 5, 10 or 20 credits and press Spin. The reels stop one after another from left to right, and whatever lines up on the middle row is checked against the pay table, which you can open on screen at any time. Every amount in it is a multiple of your bet, so a 200 for three sevens means 4,000 credits on a 20-credit spin. If several combinations fit the same line, only the biggest one is paid.
Pay table
| On the payline | Pays × bet | About one spin in |
|---|---|---|
| Seven, seven, seven | 200 | 4,096 |
| Triple bar on all three reels | 60 | 1,214 |
| Double bar on all three reels | 30 | 512 |
| Three cherries | 20 | 546 |
| Single bar on all three reels | 15 | 152 |
| Any mix of bars | 5 | 17 |
| Cherry, cherry on reels 1 and 2 | 5 | 57 |
| Cherry on reel 1 only | 2 | 7.3 |
Cherries are counted from the left. A cherry on the first reel pays on its own, whatever the other two show; a cherry on the middle or right reel with no cherry to its left pays nothing. “Any mix of bars” means each reel shows some kind of bar but they don’t all match, such as single, triple, double.
How often it pays, and where the return comes from
The frequencies above aren’t estimates. Because each reel lands on each of its 32 stops with equal chance, every one of the 32,768 possible results can be counted, and that count gives an exact return of 94.27%: over a very long run, every 100 credits bet comes back as about 94.27.
Some things the count shows that the pay table doesn’t:
- About one spin in 4.5 pays something. Most of those are small: a lone cherry or a mixed-bar line.
- Small wins carry the machine. The single cherry (about 27% of the return) and mixed bars (about 29%) together supply more than half of everything paid out. Three sevens, the headline prize, accounts for less than 5%.
- The reels aren’t identical. All three have 2 sevens, 3 triple bars, 4 double bars and 6 single bars, but the cherries thin out from left to right: 5 on the first reel, 4 on the second, 3 on the third. The blanks grow to match. That’s why three cherries (20×) is about as rare as three double bars (30×).
Strategy
A slot gives you exactly one decision: the bet size. Nothing you do changes where the reels stop, and every bet size has the same 94.27% return, so there’s no clever setting.
What bet size does change is the ride. At 1 credit a spin, 1,000 credits last a long time and a three-sevens hit is worth 200. At 20 credits a spin the same bankroll is 50 spins, and with a win only once every four or five spins, a cold patch can empty it fast. Since three sevens comes around once in about 4,096 spins on average, most sessions never see it at all, at any bet.
A few things are worth knowing because people often believe the opposite. A machine isn’t “due” after a long dry run; each spin is independent. Stopping after a win doesn’t lock in a better return. And there’s no point timing the spin button.
