7bd Slots — Classic to Jackpot, all types of slots in one place

Slot games are not purely about luck — knowing which type of game suits your budget and preference makes for a much better experience. From hundreds of titles by PG Soft, JILI, and Pragmatic Play to the complex mechanics of the Megaways engine — this guide covers everything in plain language.

Four types of slots — how each one works

Slot games are not built from a single template. Each type has different mechanics, a different payout structure, and a different feel. The four main types and their differences are explained below.

Classic Slots

Three reels and simple paylines — this design is still popular today. Straightforward fruit and bar symbols, very few bonus features, but gameplay is direct and easy to follow.

Simple Fast rounds

Video Slots

Five or more reels, multiple paylines, and rich animations. Packed with free spins, multipliers, and bonus rounds, these games make up the mainstream of today's slot market. Titles like Fortune Tiger and Gates of Olympus fall into this category.

Bonus features Theme-rich

Megaways Slots

An engine developed by Big Time Gaming — each reel's height changes on every spin, so the number of ways to win is different each time. In Bonanza Megaways or Extra Chilli Megaways, there can sometimes be hundreds of thousands of ways.

Variable ways to win High volatility

Jackpot Slots

A small portion of each bet goes into a central pool. In progressive jackpot games, this pool can grow very large. There is potential for a big prize, but regular payouts are comparatively smaller.

How to choose the right slot

Finding the right game for yourself among hundreds of titles can feel a little overwhelming. Keeping three things in mind makes the decision much simpler.

Volatility

High-volatility games pay out less often but can pay larger amounts when they do — Wanted Dead or a Wild and San Quentin xWays are in this category. Low-volatility games give frequent small wins. Choose volatility based on your session budget and patience.

Theme and Mechanics

If you enjoy cricket, a cricket-themed or sports slot can be fun. If you prefer mythology, Gates of Olympus is worth a look. Cascading reels, sticky wilds, or hold-and-win — check the mechanics before you start.

Budget Planning

Set a total budget before each session and keep each spin bet at most 1–2% of that budget. This allows you to enjoy a longer session and reduces the risk of a sudden large loss. Read the full responsible gaming guide for more advice on managing your budget.

RTP and Volatility — the story behind the numbers

RTP (Return to Player) is the average percentage of bets that a game theoretically returns over the long term. For example, Fortune Mouse has a maximum RTP of 96.96%, and Mahjong Ways 2 has a maximum RTP of 96.95%. But these figures are averages across thousands of spins — there is no guarantee of winning at that rate in a single session.

Volatility describes how often and how large the payouts are. A high RTP does not mean low volatility — the two are completely separate things. For the best experience, consider both together.

Practical tips for playing slots

  • 01 Before spending money on a new game, play it in demo mode for free — understanding the mechanics makes your real session go much better.
  • 02 If you take a big loss on a game, it is better not to immediately raise your bet to try to "come back" — take a calm break instead.
  • 03 Triggering a bonus round usually requires a certain number of scatter symbols or special symbols — read each game's paytable first.
  • 04 Before starting a session, set a win target and a loss limit, and stop when you reach either one.
  • 05 Playing regularly in the 7bd VIP programme earns weekly cashback — visit the 7bd VIP page to see the full details.

Common misconceptions about slots

Myth

"If you haven't won in a long time, you're more likely to win now"

Every spin in a slot is independent and random. The result of a previous spin does not affect the next one — this false belief is known as the gambler's fallacy.

Myth

"A higher bet increases your chance of winning"

The RTP percentage does not change with the size of your bet. A higher bet means the potential win is larger, but the potential loss is equally larger.

Myth

"Playing at a certain time of day makes it easier to win"

In games using a licensed RNG (Random Number Generator), the time of day has no effect. Playing at night or in the morning — the outcome is completely random.

Frequently asked questions about slots

Yes, significantly different. Regular video slots have a fixed number of paylines or ways — such as 243 or 1,024. In the Megaways engine, each reel's height changes randomly on every spin, so the number of ways to win can range from a few thousand to over 200,000. Bonanza Megaways and Extra Chilli Megaways are well-known examples of this engine.

RTP is a long-term average — a theoretical figure showing what percentage is returned after thousands of spins. It has no direct effect on a short session. You can still lose in a single session playing Fortune Mouse (maximum RTP 96.96%), and a big win can come from a lower-RTP game — it all depends on the random number generator.

Low-volatility video slots are the most suitable for beginners. They pay out small wins frequently, so your balance does not run out quickly and you get enough time to understand the gameplay. Once you understand the mechanics, moving to high-volatility or Megaways games becomes easier. Try any game in demo mode before playing for real.

In most video slots, a free spin round starts when a set number of scatter symbols land on the reels. During this round, spins cost nothing and multipliers or special features are usually active. Bonus rounds vary by game — sometimes pick-and-win, sometimes a wheel spin. The details of these features are listed in each game's paytable.

7bd's slot games are built in HTML5, which runs smoothly on both Android and iOS devices. You can play directly from a browser. 7bd also has Android and iOS apps available through official channels. The mechanics stay the same on a smaller screen — only the layout is adjusted to fit mobile.
