    The evolution of slot machines traces back to 1891 when Pitt and Sittman invented the poker machine made up of 5 drums and 50 cards. In 1895, Charles Fey created the first slot machine known as the Liberty Bell. The Liberty Bell slot machine featured a lever, 3 reels, and automatic payouts. The 19th century has been marked by remarkable transformations through the introduction of video slots.

    Today, there is a wide range of slot machines available in the gambling market. These slot machines can be generally categorized into downloadable and instant-play slots. Downloadable free slots offer great graphics and smooth gameplay. No download casino slots are online slots which do not require players to download them to play. They rely on browser plugins hence the name “instant-play” online slots. No download slot machines are based on a Random Number Generator (RNG) system, which produces millions of possible results per second. RNG picks a single result where the slot game lands on.

    How to Play Free Slot Machines

    Free no download slots have their license information on the footer section of their web pages. Players need to check an online slot volatility index before they start to play slots for fun with no download or for real money. Most free online slots by the chosen providers at Red Dog Casino offer a high return to player (RTP) rates to create a better gaming environment. Control buttons and special symbols are key features when gamblers play free slots without downloading.


    Control Buttons

    Control buttons are key features in any free slot without download. A player has to understand them before starting the game. Some of the common control buttons include:

    • Spin Button – This is the ignition key to the reels. When a player presses it, the reels will start spinning.
    • Stop Button – This control button stops spinning reels and gives the final combination of symbols on the slot machine reels. By pressing the “Stop” button, a player can win huge results.
    • Gamble Button - This control buttons offer a player a chance of increasing their winnings by placing them as a wager for the next round.

    • Bet Per Line - For casinos that do not have fixed paylines, it is possible to adjust the number of active paylines per spin. The more line a player picks, the more chances of winning they secure.
    • Autoplay Button – This button allows a player to set the number of times the reels can spin automatically without interruption. In most free online slots with bonuses no download, you will find a preset number of rounds that you can pick from.
    • Turbo Button – Just like in motorsports, the turbo button is all about speed. This control button allows a player to spin the reels a bit faster than usual.
    • Sound Control Button – Players have different playing environment preferences; this button helps you decide whether to listen to the game soundtracks or play in a silent environment.

    Special Symbols

    Besides the common and basic game controls, a player must understand the special symbols in free casino games with no download needed. Special symbols enhance the gaming experience by giving players more wins and bonus round features. When two or more special symbols appear anywhere on the reels, they trigger a bonus round or scatter wins.

    The wild symbols in a free online slot substitute all other symbols except the scatter symbols to form a winning combo on an active payline. It might double or triple the wins in some online slots. There are several types of wild symbols:

    • Stacked Wilds – They pill on each other to fill the reel and rewards heavily when they appear. They appear during the base game and bonus rounds.
    • Sticky Wilds – They may appear in the same positions for several spins to reward consecutive wins.
    • Expanding Wilds – They appear stretched by forming a bigger symbol which fills a whole reel and helps a player get better rewards.
    • Shifting Wilds – They are sticking between spins but keep changing their positions from the first reel up to the last reel and disappear.
    • Transferring Wilds – When they appear on the reels they replicate themselves on the adjacent reels to increase player payouts.

    Each bonus round has different multipliers. Special symbols are behind the rapid growth of most casino games in recent years.

    Buy-Your-Pay slot machines are the innovation behind the Bet per Line option in the casino today.

They feature 5 reels with more symbols and adjustable or fixed paylines, which create more winning combinations. They come with digital reels and spin control button to replace the old lever designs. Besides, video slot machines offer better graphics and sound effects in comparison to classic slot machines. These slot machines marked the introduction of first progressive jackpots and bonus rounds. Although video slots made a big impact on land-based casinos, they also played a major role in the prominence of casino sites online.

    Progressive slot machines can be defined as slot machines with a jackpot that increases with every spin. They offer huge jackpots that are awarded randomly or during bonus rounds, or through a combination of matching combinations. The progressive jackpots take a small percentage of every bet and add it to the total jackpot amount until it is won. Progressive slot machines can be further subdivided into:

Whether a newbie, semi-pro, or veteran player, every player must develop a strategy before playing any slot game. Here are some great tips for smart slot play:

    1.Bet the Maximum

    Betting the Maximum might look a bit risky, but it is a recommended strategy. Most online slots allow players to adjust the number of active paylines per game, which in turn reduces or increases the chance to land the winning combinations. Besides, some special features such as progressive jackpots and bonus rounds are only activated if all the paylines are active. Always keep all the paylines active and enjoy more rewards than with adjusted paylines.

    In most free slots with no download, the return to player rates depend on the coin size or bet amount per spin. Playing for higher denominations increases the chances of landing a great winning combo. Also, high denominations have bet payouts when multipliers are applied to a winning combination.

    3.Play Demo Version

    It is advisable to play a demo version of any new free online slot before betting real money. This prepares the player for any special features or symbols in advance. Also, the demo version allows a player to develop a strategy on how to stake during a base game.

    4.Avoid Tight and Complicated slots

    Popular online slots have simple gameplay and better odds. It is good to avoid any new complicated online slots which are likely to offer lower odds.
