Slot machines are present at most – if not all – online casinos. They vary from simple to complex. There is the iconic three-reel game with a single payline based on the classic one-armed bandit game. At the opposite end of the scale, there are video slots based on five reels (occasionally more). These offer multiple paylines and often special features too such as bonus rounds, click me features, and free spins.

Slot games are simple to understand and play. The house edge varies from around 10% (around 90% RTP or return to player for the participant) to 1% in the best cases (99% RTP).

Online slots offer paytables filled with prize potential. Some might offer progressive jackpots too. The idea is to find enough matching symbols across a payline to win a prize. Wild symbols stand in for others to increase winning chances. Scatters pay out wherever they land if you find enough of them.

Bonus rounds are often triggered by different icons. The scatter usually triggers the free spin feature. Different slots are inspired by different themes. Every player can find plenty of opportunities to play slots that appeal to their budget and preferences. Bets often start from as little as one cent per line.

Roulette is available in several variations at many online casinos. Each version of the game involves a table with a selection of betting options printed on it. These are usually displayed on a green sloth background. The roulette wheel shows all the numbers involved in the game and those excitedly making their selections sometimes have a system , superstition or luck as way of making their selection.

A small ball is then spun in the opposite direction to the wheel spin. It then stops on a number. All winning bets are then paid out, with the house retaining all losing bets. Of course with online roulette the principle is the same just with a virtual environment in place of the physical.

American roulette has a single zero and double zero occupying two spaces of the wheel. This means the house edge is higher at 5.26%.

European roulette is more attractive as it does not have the double zero in play. This reduces the house edge to 2.7%. There are two versions of European roulette – one with a standard table and another with a racetrack. The latter includes additional bets such as orphelins.

French roulette is another option, offering the opportunity to receive half your losing bet if you are incorrect at guessing an even chance bet.  If you guess odd and the ball falls on even, 50% of your bet would be returned. Big win online casino options are available for all, and the thrill of roulette is something we’re likely all familiar with.

Many online casinos offer standard roulette games, with some adding live roulette to the mix as well. Roulette lovers and spoilt for choice!

The Big Six Wheel game started life as a carnival attraction. It made its way into land-based casinos before popping up at online casinos as well.

The name comes from the wheel format. It offers six potential outcomes for each spin. The default wheel has 52 slots the pointer could stop on. There are 24 slots offered at even money. Another 12 slots provide odds of 3 to 1.

As the slots reduce in quantity, the odds get longer. Other standard outcomes include eight slots at 5 to 1 odds, and four slots at 10 to 1 odds.

This leaves four slots remaining. Two offer odds of 20 to 1, while the final two offer the biggest prizes if you manage to stop the pointer on either one of them. If you could manage it, the prize would be 50 to 1 on your placed wager for that spin.

The game is also known by other names such as Money Wheel or the famous Wheel of Fortune. It is one of the easiest casino games to play as no skill is needed. Simply place a bet and wait for the wheel to spin and stop on a slot to see if you have won.

Keno is a popular alternative game offered at numerous online casinos. Like a lottery game, it is one of the easiest games for beginner players to try.

The standard game offers numbers between one and 80. The idea is to choose 15 numbers. The game then randomly produces numbers to see how many you can match. Twenty numbers are drawn by the game to determine the outcome.

There are other variations that sometimes appear. 40-ball keno uses half as many balls, while the player only selects 10.

Another variation involves a bonus ball. If you correctly match it, a bonus prize is granted.

Odds vary for keno depending on how many numbers are matched in a game. While standard keno allows you to choose 15 numbers, you don’t need to choose that many. Doing so extends the odds. The more numbers you pick, the more balls you need to make a successful match for a prize.

That means better odds are available if you select between six and eight numbers. Odds can range from one in four when a single number is correctly chosen to one in 20 if you choose 10 numbers and need five to secure a prize.
