What are No Download Slots?

The first step to understand online slot games is to recognize the features of all subdivisions. The next step is to choose according to features. We have classified all the slots categories according to their features without any download.

Register to any casino for free to play any of the no download slot games. Take the example of Thot Slots; we don't require our players to download special software to play any bonus slot games. As a funded member, you can access any slot game, and it downloads within seconds. The online denomination below is a guidebook for players to choose no download slots according to their features:


It's the best online slot feature that let players spin reels in intuitive mode. There is no need to click on the spin button every second to adjust the settings, and you are good to go. Try Quick Hit and House of Fun to give autoplay features a run. This feature always ends when the bonus spins of the game are triggered.

Bonus Game

Slots with bonus games are always popular among players, and when they are free, there is nothing to stop players from spinning the reels. Monopoly and Wizard of the Oz are bonus packed slots that will keep you on edge, while offering good chunks of cash.


Slots with multipliers increase your payout whenever you win. These multipliers increase your winning up to a certain amount of 2x, 5x, 10x and so on. Wheel of Fortune is the best example for Multiplier slots as the wheel displays many multipliers on its colourful segments.

Progressive Jackpot

The increasing jackpot with every wager is the most favourite slot category of every player. Especially when the pot reaches millions, players' hopes increase with every spin. You never know which spin can win you a 6 figure reward. Mega Moolah is an interesting progressive jackpot title that has rewarded players millions up to date. Some Microgaming casinos even offer a download version of their games

Multiple Free Spins

These free spins are the most rewarding bonus rounds as there is nothing to lose on the player's end. You can collect the right symbols and win the multiple free spins rounds on the Cleopatra slot.

Why We Prefer No Download Slots

Why download online slots when you can play without downloading. When searching for online casinos, you may come across some brands that give players access to their game after downloading special software.

Sometimes that's all you have to do other times; you need to download another software to play games as well (one time is enough to play all the games)

Let's get into the details of no download free slots. You won't require any special software to play slots for free. A simple 5-minute free registration and a deposit that takes only seconds are enough to unlock all features. After profoundly analysing both download and no download slots, we prefer the latter because:

  • Download Slots require special software to operate and no download slots play directly in your HTML5 browser.
  • Many players want to avoid downloading as it's a hassle, and playing free slots saves them from trouble.
  • Slots are only playable on the device with software, whether it's desktop or mobile. Online free slots don't restrict players from playing games on any device.
  • Most software is only compatible with Windows on desktops making it difficult to play these slots.

After reading these comparisons, you can understand why we prefer no download slot games. Try our Real Money online slot with and without free spins on Thor Slots in an instant.
