How Classic Slots Work
Classic slots are simple to play and work easily. You find wide variety in these games in terms of themes but the basic similarity is there in all: they come with 3 reels and have a very antiquated look about them. The classic slots you find at online casinos are usually copies of what you get at land-based casinos say, in land-based casinos in Vegas and other such gambling hotspots.
The way they work is simple. You sign up with the online casino and deposit funds for real money play. You zero in on the classic slots available here and click on the one you want to play. Choose your coin value and then place your wager by zeroing in on your coin size to avoid frustration and helplessness later. Aiding you in this decision is the paytable; it gives you a good idea of the advantages the different coin sizes come with.
Most classic slots have a single base game; there are no extra bonus rounds to spice things up. If at all any one of these has a bonus round it will have more than a single payline. The payouts for these games are not too high but they are fun to play.
What Are The Types of Free Slots?
You get different kinds of classic slots to try out when you are playing at an online casino.
The most commonly seen ones include:
-
Classic 3-reel slots with fixed jackpots
These games have 3 reels and a fixed jackpot. The number of coins allowed is also less, and they have a fixed jackpot as the title says. You have the liberty of playing with anywhere between 1 and 9 coins.
-
Classic 3-reel slots with progressive jackpot
These are classic 3-reel slots that come with a progressive jackpot that can completely change your life for the better. You can play for the progressive jackpot only if you qualify to win it. You stand the chance of winning the progressive jackpot only if you play Max Bets.
-
Classic 3-Reel slot that gives bonuses for playing maximum coins
These slots give you extra bonuses should you opt to play in Max Bet mode.
-
Classic slots with 4 reels
Also called wide area progressive slots (WAPS) and could have up to 4 reels. The first of these was developed by International Gaming Technology (IGT) back in the 1980s. Because there is a progressive jackpot attached, the chances of winning are less.
-
Classic slots with accumulator bonuses
Also called Variable State Slots, they pay out bonuses only if you land your bouquet of winning symbols or permutations and combinations of them in a bank. It is only post this that the bonus gets activated.

FAQs Concerning Classic Slots Bonuses
Classic slots tend to have only three reels. This is very similar to many video slots also, but just because a slot has three reels does not automatically make it a classic slot. Another way of identifying a classic slot is the symbols they use, many of which you will be familiar with, such as:
- A Ace
- K King
- Q Queen
- J Jack
- 10 10
Cherries- Liberty Bell
Lucky Number 7
All slots (including classic slots) have a predetermined RTP (Return to Player). This number determines the slots odds in the following way: the higher the RTP of a slot, the more likely it is that you’ll spin a winning combination. For example, if you wager £100 on a slot game with an RTP of 98%, you will win back, on average, £98. Our top pick of classic slots with a good RTP% (and great gameplay), includes the following:
| Rank | Slot Title | Software | RTP |
| 1. | Triple Profit | Playtech | 98.72% |
| 2. | Jungle Boogie | Playtech | 97.40& |
| 3. | Hot Shot | Bally | 97.15% |
| 4. | The Rat Pack | Microgaming | 97% |
| 5. | Diamond Mine Deluxe | RTG | 96.43% |
There are many software providers which excel when it comes to classic slots. However, it can be argued that classic slots games have been overtaken, convincingly, by video slots in terms of popularity. Nonetheless, the software provider, Playtech, has a number of classic slot games which are popular amongst players looking for a more traditional experience.
