Tips & Tricks to Boost Your Odds of Winning Slot Games

Online slots are entirely random. Therefore, there is no winning recipe that will guarantee a winning spin. You can, however, give yourself the best chance of winning by applying a few tips and tricks. Here are our top five tips on how to boost your odds of winning slot games.

1. Practice With Free Games

Before playing slots for real money, try the demo versions of slots – it’s free! Practicing with free games will help you hone your skills and allow you to get to know the game. After joining a casino, go to the slots and hover over a game with your mouse to see which you can play for free.

2. Choose Your Slot Carefully

Not all online slot games are the same. Games vary in volatility, theme, features, soundtrack, RTP, and size. Find games with a Return to Player (RTP) rate of 95% and more. In addition, choose a game that you will enjoy playing.

3. Study The Pay Table

The pay table shows all the symbols and their worth. It will also describe the scatter and wild symbols and what combos will be the most lucrative. A slot game with many paylines provides more chances of a winning spin.

4. Aim For Smaller Jackpots

Select a slot with smaller jackpots – they tend to pay out more frequently. Progressive jackpot slots are very tempting, but your chances of winning are slim. In addition, bet smaller stakes to give you more chances of a winning spin. This will also help you play for longer.

5. Stick To Your Budget

Before you start playing, set a budget and stick to it. Decide what you will spend upfront, and stay within your limits. Play responsibly. It will remind you to play for fun and keep you from chasing those big bucks.

Popular Types of Slot Games

Slot games come in various types, each with unique features and characteristics. Below we describe the three most popular types of slot games and how they work.

Video Slots

Gonzo's Quest

Video slots feature an extra layer or two of multimedia. Compared to classic slots, the payout is much higher as video slots have in-game bonus rounds. In addition, video slots come in various themes, gird sizes, and features.

Progressive Slots

Devine Fortune Slot

Progressive slots take an amount of every bet you make and add it to the jackpot prize. The jackpot keeps rising until someone hits the winning spin. Some progressive slots are interlinked with other slots, increasing your chances of a bigger jackpot!

Classic Slots

Inferno Star Slot

Classic slots have straightforward gameplay, a simple design, and easy-to-understand paylines. The payout is much smaller than with video and progressive slots but appeals to many players with its old-school charm. Classic slots usually feature fruit, lucky 7s, and bar symbols.

Playing Free Online Slots Ireland

Playing free online slots is a great way to practice before playing for real money. In addition, it’s a great way to decide if a slot game suits you. Many Irish online casinos provide online slots in a demo version, offering excellent free play opportunities.

What’s great about playing free online slots is that the rules and mechanics work the same way as the real deal. Instead of risking your real money, you use fake money. Play as many demo games as you want until you feel ready to play with your bankroll.

The Best Bonuses for Online Slots

There are excellent bonuses for Irish players at online casinos up for grabs. All reputable casinos offer a welcome bonus to new customers and a constant stream of ongoing bonuses and promotions. Below we review the most popular bonus types and where you can find them.

Welcome Bonuses

The welcome bonus is reserved for players who register at a casino for the first time. This bonus is usually very generous, but you can only claim it once. The welcome bonus usually offers a deposit match up to a maximum amount.

All welcome bonuses come with wagering requirements, which you must fulfill before withdrawing winnings. Review the welcome bonus before opting to ensure you meet the conditions in the specified time.

Free Spins Bonuses

The free spins bonus is the best bonus offer aside from actual cash. Casinos offer free spins to reward loyal players and will often limit the free spins to a specific slot game. So when using free spins, you can win real money!

Free spins are often incorporated with welcome bonuses, making the offer more generous for newcomers. Check the promotions section of the online casino to find a free spins bonus. In addition, some brands offer free spins through the VIP program or as an ongoing promotion.

Powbet Logo 100% Bonus up to €500 + 200 Free Spins Claim Here

No Deposit Bonuses

No deposit casino bonuses are the most sought-after offers and are pretty hard to find online. The bonus usually awards free spins or credits as a thank-you for joining the casino. Free spins bonuses come with strict T&Cs, so remember to read those carefully before you opt in.

At the time of writing, none of our recommended sites offers no-deposit bonuses. You can, however, visit our top online slot casinos for the best selection of quality slot games. In addition, they provide a generous welcome bonus and excellent ongoing promotions.

Comparing Mobile Slots to Desktop Slots

One of the great perks of online casino slots is the versatility it offers its players. You have a vast library of slots and can play mobile slots online. The exact online slot bonuses apply on mobile devices as on desktops.

Players can enjoy the same immersive gaming experience on Android and iOS mobile devices. Thanks to HTML5 technology, the software is fully optimized for mobile online slots gaming. Play online slots for real money on mobile using your mobile browser or downloading an app. We recommend you try any of these three top casinos on your mobile device.
