Most free online slots by RTG provider 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.

• 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.

For example, in Dream Run slot by RTG at Red Dog Casino, 3 or more scatter Green Traffic light symbols activate the Dream Run Racing Feature. This feature takes the player into a bonus racing event where the player is only prompted to pick a car to start a race. The position of the player’s picked car determines the wins and whether they qualify for the next round. Each bonus round has different multipliers. Special symbols are behind the rapid growth of most casino games in recent years.

Types of Slot Machines

The recent decades have recorded a massive evolution of slots from the classic 3 reel machines to the current 3D machines. Slot machine providers have embraced new technology in their sound and graphic effects as well as the general game theme. The need for a better gaming experience has driven all these changes. All these transformations have been marked by different types of slot machines. Below, you will have insights into the most common types of slot machines:

• Classic Slot Machines

The Classic Slot machines mark one of the oldest types of slot machines in the casino industry. It features 3 reels and simple gameplay. They offer high chances of winning mega jackpots. This is the reason behind their popularity and recognition by veteran casino players. Examples of classic slot machines include Red Classic, Original Blue, and White Classic slots. Today, some of the classic slots have been improved to run on 3 or 5 reels.

• Single-Coin Machines

Single-Coin machines are very rare today in the casino market. They have been substituted by newer slots that offer multiple coins per spin, just like wild symbols replaces other symbols in gameplay. Software developers focus more on improving the gaming environment, which has been a key determinant in the casino market. However, some casino establishments still offer Single-Coin slot machines to folks who are risk-averse.

• Buy-Your-Pay Machines

Buy-Your-Pay slot machines are the innovation behind the Bet per Line option in the casino today. This type of slot machine allows a player to choose the number of winning combinations by the coins they insert. A single coin might only offer three bars as the online winning combination, even if more combos are available. The more the coins inserted, the more the winning combinations. Most Buy-Your-Pay Machines accept between one and five coins per spin.

• Video Slot Machines

Video Slot machines are creations of the 19th century and later-day slot machines in the casino market. 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

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:

• Stand-Alone Progressive slots – They are independent and offer small wins.
• In-House Progressive slots – They are linked to other slots in the same casino and offer better winnings.
• Wide-Area Progressive slots – This type of progressive slots are interlinked with other slots, and it offers the highest jackpots.

At Red Dog Casino players can find several progressive slot games that are combined in the game lobby into a separate category with the same name.

Types of Slot Features

A player should look for a free online slot with excellent features that pay well. Some of the slot features that you will come across as you play free online casino games for fun with no download include:

1. Paylines – These are winning combinations that reward players. A classic slot machine has 1 to 3 paylines with video slots having up to 1024 paylines. Normally, paylines reward from the leftmost reel to the right one for any 2 or more symbols. However, multi-way slots reward in all directions.
2. Free Spins - Players can trigger free spins by landing 3 or more scatter symbols anywhere on the reels during a base game. The number of free spins varies from one slot to another. In most cases, the number of free spins is specified in the pay tables. More reels or special symbols might be added during bonus rounds.
3. Cascading Reels – Whenever symbols form a matching combo, they explode and move down to create a space for new symbols that drop into place and allow the player to earn more matching combos. The cascading feature continues until no more winning combos appear on the reels.

Tips for Smart Slot Play

When playing free online casino games for fun no download at Red Dog Casino, players might find this guide helpful. They will be able to know how to set a loss limit and avoid unnecessary risks. 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.

2. Play Large Coin Sizes

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. Some new complicated online slots might have attractive bonuses, progressive jackpots, or multipliers, but it is good to avoid them. Tight slots are frustrating and have very low returns to player rates.

Free Slots to Play for Fun

Becoming a successful gambler is not as easy at it seems, as you need to master a lot of things:

• Financial management. Managing your money the right way should be the first thing on your list. Therefore, you will need a bankroll. A bankroll is a certain sum of money that is used exclusively for playing. You don’t spend it on buying food, paying bills, or any other expenses. It is a money supply that serves as a wallet to deposit and withdraw payments. Sure, you can cash out some of the money from your bankroll, but only when they exceed a certain amount. For example, if your bankroll is $2,000, and you have won $200, you can withdraw $200 painlessly. It is only up to you to set a bankroll amount. It all depends on your goals and the games you are going to play. Let’s imagine that you are an average gambler that wagers not more than $5 per spin. Therefore, if you bet $1 per spin, you will need a bankroll of at least $2,000 – $3,000. And that is the minimum bankroll. Ideally, the bankroll should be even bigger, especially if you are serious about online gambling. The reason why you need so much money is that you will most likely have to deal with an unlucky streak. And in order to withstand such a bad streak, you need a decent bankroll.

For example, with a bankroll of 1,000 bets, you can easily lose 100 or even 200 times in a row without major consequence. Such losses will be perceived as temporary and nothing more. However, the most important rule of bankroll management is to never bet with the money you can’t afford to lose. This means that betting your salary (which also needs to be spent on food, rent, clothes, etc.) is not only stupid, but also very dangerous.

• Random Number Generator(RNG). If you want to make money gambling online, you need to have a good understanding of the role of the random number generator. Most importantly, each spin is an independent trial. The machine itself does not know whether you won in the previous slot, it only receives a set of numbers from the RNG and visualizes the information on the screen. Thus, if you have lost a significant amount of times in a row, there is no guarantee that you will start winning over and over.
• Dispersion. Modern online casinos require you to take big risks if you want to win a large sum of money. That said, you need to do it wisely. In order to play smart, you need to always familiarize yourself with the principle of the slot machine. First of all, make sure to study all of the bonuses presented, including Scatter and Wild symbols. The second thing is just as important: study the rules of the game. You can do so by clicking on a question mark presented at the top of the slot. You will find all of the necessary information there For example, Scatters can appear both in the bonus and in the main game. All bonus features are also explained there, and most importantly, the player’s theoretical income (RTP) is indicated. On the other hand, no one objects to the game on machines with low volatility. In fact, you can win a couple of hundred bets easily. And even though lower-risk games offer lower-value win, you can significantly reduce the requirements for the bankroll – for example, to 600-700 bets. This is a great choice if you are playing free casino slots just for fun.
• Bonus rounds. Bonus rounds aren’t as profitable as you think. More precisely, it’s best to play such a game if the winning amount is relatively small, like $5 or $10, as it won’t affect your bankroll in any way. The main problem is that in most cases such bonus rounds are designed to increase the house edge. Most of the time you have less than 50% to win.
• Betting range. The betting range depends on the slot. It can be from $0,20 to $100. However, in most cases it is best to bet as little as possible. In modern slots, there is no binding to maxbet, i.e. when playing at any bet, the machine behaves the same way. However, it is important to play on all the lines. This is the only way to guarantee the inclusion of all scatters and bonuses. You can always reduce the number of coins per line, but not the number of lines. In general, it is better to take the minimum bet. And if you enjoy playing at $0.25 per spin, you can continue playing at this rate. The high variance will allow you to win a decent amount of money, even if you bet low.

A Brief History of Free Casino Games No Download No Registration

The history of slot machines is somewhat different from gambling itself, and goes back to the days when online gambling was not even an idea, let alone a reality. In 1891, Sittman and Pitt developed a slot machine that became the forerunner of modern slots. It consisted of 5 reels, 50 cards and was based on poker.

The first real video slot was created in 1976 in California by N. Serraschio, R. Green, W. Beckman, J. Reukes and L. Black under the leadership of Fortune Coin, based in Las Vegas. And the first online slot was developed only in 1994. It was a slot machine with three reels and one payline.

Over the years, there are more and more slots with a different number of reels and a variety of paylines, including the 3D slots with a fantastic animation.
