Sorting & filters

advanced

To sort slots, our search engine lets you find a specific free slot. Enter part of the name and you’ll get matching results. You can also use our filtering system to refine based on what you want. Filtering by provider is a great start if you prefer specific studios. Or add many criteria: buy bonus option, Megaways, free spins, progressives, popular picks, or even the latest online slots just released! Take your pick and find the perfect free online slot.

Some games offer Free Spins, free rounds that let you spin a set number of times without betting. Some slots feature a progressive jackpot, a shared pot that grows with each bet; a small percentage of your stake feeds the jackpot, giving you a shot at a big win. You can also sort slots by volatility or RTP, or find those with wilds, scatters, or win multipliers. The Buy Bonus feature is now very popular too, letting you access a bonus without the wait.

These slots are hugely popular, but not all for the same reasons. Some blow up online thanks to Twitch streamers and long sessions (think Pragmatic Play’s Big Bass Bonanza). Others are classics in land-based casinos worldwide (like Book of Ra) and look a bit older than the new generation… that’s part of their charm. If you haven’t tried them yet, you really should in demo mode.

Technical characteristics of slots

Technical characteristics form the backbone of a slot: reels and rows, paylines or ways to win, RTP and volatility. Together, they shape the layout, win frequency and the overall game feel. To compare quickly, our guide lets you filter titles by these criteria.

Good to know before you start:

Reels

Every slot uses reels, the spinning columns that move when you press play. Most modern slots have 3 or 5 reels, sometimes 6 or more. Our guide can filter by reels. Simpler games often have three; newer ones usually have at least five. Find all 3-reel slots and 5-reel slots in our guide!

Paylines

Your goal is to complete a payline with several matching symbols in order. Paylines are the paths symbols must follow to create a winning combo; sometimes adjustable or fixed, sometimes paying both ways. 5-reel games often have more paylines than Fruit Slots or classic 777 slots. Newer games with Scatter Pays or Cluster Pays now offer a different way to win.

Rows

A reel holds one or more rows of symbols (vertical), not to be confused with paylines. You’ll often see one, three or four rows per reel, sometimes more, e.g., in Megaways slots where row height varies between 2 and 7 each spin.

RTP (Return to Player)

Each casino game has an RTP, the average percentage of stakes paid back to players over time. For example, 96% RTP means the casino keeps the remaining 4% long-term. Physical casinos average ~85%, while online sites with lower overhead can offer up to ~99%. If you’re just playing free slots, don’t worry about RTP.

Volatility

Volatility measures the swing of results. High-volatility slots pay less often but can hit bigger prizes; low-volatility slots pay smaller wins more frequently.

Providers / Studios

Many companies supply games to online and land-based casinos, often called providers, developers or studios. You’ll find 100+ on our guide. Big names include Pragmatic Play, Play’n GO, IGT, Light & Wonder, and more.

Themes

Every casino game has a theme (adventure, animals, war, fantasy…). To refine your search, our guide assigns each slot two themes, there are 50+ across the site.

Progressive Jackpot

Progressive slots are linked across casinos that host the game, sharing a jackpot that a lucky player can hit at random. The jackpot grows continuously with a percentage of all stakes. Some progressives are hugely popular and can reach millions, like NetEnt’s Mega Fortune, Microgaming’s Mega Moolah, or Yggdrasil’s Holmes and the Stolen Stones.

Mechanics & bonus features

Bonus mechanics bring the game to life. Beyond Free Spins and Wilds, there’s a lot to explore: Megaways, cascading wins, bonus games, buy bonus options… These elements shape the game’s pace, boost potential and enhance the feel. Below are the most common ones, each clearly defined, and our guide lets you filter by your favorites.

Essential game options & special symbols:

Megaways

The licensed BTG Megaways system varies the number of winning ways on every spin. Reels can show 2–7 rows, creating up to 117,649 ways. Big Time Gaming uses it, as do Pragmatic, Red Tiger, Stakelogic, etc.

Buy Bonus

More and more slots offer a buy feature so you don’t have to wait for the bonus to trigger. Purchase instant access (often to Free Spins). RTP is often higher when the bonus is bought.

Win multipliers

Some slots add multipliers via consecutive wins or special symbols. When several are visible, multipliers may either add or multiply together.

Cascading Reels / Avalanche

Often found in Cluster Pays slots (but not only), it removes winning symbols so new ones fall into place, letting you chain multiple wins within a single spin.

Free Spins

Many slots award free rounds when triggered, often by landing three bonus/Scatter symbols. Sometimes you can buy them or win them in a bonus game. The number of spins varies by title and number of Scatters.

Bonus Game

Bonus mini-games usually trigger with 3+ bonus symbols anywhere. You’ll find Hold & Win, board games, pick games, wheels of fortune, studios keep innovating with fresh bonus ideas.

Wild symbols

A Wild is a joker that substitutes most symbols except specials. Variants include Expanding Wilds (cover a full reel), Random Wilds (drop anywhere), Sticky Wilds (stay for a respin), and Stacked Wilds (appear in stacks).

Scatter symbols

Scatters usually pay when you land at least three anywhere; they don’t always need to align on a payline and often trigger bonuses or free spins. Wilds can’t substitute them.

Click Me

Pick-&-win mini-game: click a symbol to reveal an instant prize.

Respins

Extra spins awarded via features, e.g., locking a Wild or triggering a respin bonus.

Gamble / Double

After a winning spin, gamble to double (or x4) your win, at the risk of losing it. Usually a guessing game (e.g., card color).

Autoplay

Autoplay (auto-spin) lets you run multiple spins without pressing play. Most modern games support it; set up to 100 spins, or stop on win/loss limits.

It depends on you, use our filters. You can pick a slot by:

Return to Player (RTP)
Volatility
Theme or preferred provider
Built-in features and jackpots

Some strategies help: choose higher-RTP games, and set limits so you know when to stop. Practice also helps you gauge volatility.

RTP, payout rate, return rate, it’s the same concept: the average percentage paid back to players. It’s sometimes shown in the in-game info panel or listed in our review.

No, slots aren’t rigged. Games are secured by the developers and audited by authorities. A random number generator (RNG) ensures outcomes are purely random.
