We all know playing free online slots is a thrill and a great way to pass the time. But it gets all the better when you start to play online slots for real money. Knowing how to maximize your earnings is easy as long as you follow a few key tips and tricks.


Your bankroll is the amount of money you have to play with and win. Building your bankroll to be able to play longer and win even more is one of the keys to playing slots for real money online. Bankroll strategy is really pretty simple when it comes down to it. Experts advise you to start slow. Most experts will recommend you start off playing for free, to familiarize yourself with a particular slots features, including free spins, bonus rounds, wilds, scatter symbols, paylines and added features. Our slots reviews will give you an in-depth overview. Then try a game for yourself for free. If you start to get that delightful feeling that you’ve found the lucky slot for you, then it’s time to play for real money and shoot for the jackpot.

Start off slow, with smaller bets at the beginning. Once you have a good feel for the slot, it’s time to start to bet slightly higher amounts, making sure to take advantage of any given slots multiple paylines. As your returns accumulate and if you feel that the slot is loose, i.e. paying out regularly and hot, i.e. paying out large amounts, it’s time to start rationing your bankroll so that you can bet and win higher and higher amounts, while still having enough of your bankroll left over to survive a cold streak.

What to do if the slot goes cold? Start to reduce your bets to maintain your playtime. If the slot remains cold, it’s never a bad idea to move on to another slot. Again, start out slow, feel the waters if you will, and then incrementally increase your bets as the slot starts to pay out.

Whether or not you decide to bet max is up to you, but if a slot is loose and starting to pay out regularly, and your remaining bankroll can support it, if you get that gut feeling that today’s the day and lady luck is smiling at you, bet the max paylines with largest amount your bankroll can take and walk away a true winner.


Selecting the right online slots game for you is as much an art as a science. First off, assess your mood. What type of adventure would you like to have? Are you looking for maximum returns and don’t care about the theme all that much? Consult our slots reviews and look for the games with the max amount of paylines and largest jackpots. Feel like a particular type of adventure? Browse through our thousands of free online slots games to find the slot that strikes your fancy. It’s always a good idea to play a few games for free, to make sure you really like the look, feel and features of the slot you have chosen.

Take time to shop around and experiment, it’s usually worth the time before starting to play online slots for real money, as you’ll be making a more informed choice, making sure you’ll definitely enjoy the game, no matter the real money outcome. The combination of having a good time with the very real possibility of substantial earnings is a winning combination. Much like an ice cream flavor, be sure to select a game you genuinely love and enjoy.
Playing for real money and winning then ends up being the cherry on top of an already delightful experience.


Unlike the mechanical slots machines of old, todays online slots are pretty sophisticated devices. Back in the day, gears, springs and a lever were used to operate the slot machine.

Today’s slot machines, whether at a brick and mortar casino or here online at Slotu, use complex algorithms and random number generators to determine the outcome of any given spin. Random Number Generators (RNGs) ensure that each spin is unique and, statistically, always a completely separate event from the previous spin. This means that looking for patterns is a bit of a no go. They call it the gambler's fallacy, the state of mind in which you begin to think, because a certain symbol has appeared a certain number of times in a row that it has an increased chance of appearing again.

Statistically, this simply isn’t true when it comes to RNGs. That doesn’t mean that slots can’t be loose or hot. Certain machines really are programmed to pay out more than others. Usually lower jackpot machines will pay out more regularly but smaller amounts. Higher jackpot machines, when you reach the hundreds of thousands of dollars or even millions, are less likely to pay out as often and will pay out smaller amounts when they do. This is the cost of going for the gold. However, when you hit the jackpot on one of these machines, it’s not just a game changer, it’s a life changer. No risk, no reward as they say, but more on that later.


Look for simple, easy to play slots and play for free to familiarize yourself with different slots functions. Learning how multiple paylines work, for example, will enhance your game playing experience when you move up to more complicated 3D and movie themed slots. Much like a pinball machine, it’s good to get a feel for where the bumpers are, how the action works, etc. on simpler, straight forward machines, before you head to the top-of-the-line multilevel, multiball games. The same is true for online slots.


Once you start playing online slots for real money, it’s important to get a feel for the flow of the game on any particular machine. Slots machines are said to go hot and cold. Start off with smaller bets that don’t put too much strain on your bankroll to get a feel for how the machine is responding to you on any given day. If you get the feeling that the machine is loose, and you keep hitting free spins, bonus rounds, prize multipliers and other features, it may well be time to start betting max on your way to that mega win. Play as many paylines as you can to increase your chances. Above all, keep an eye out for the right time to jack up your bets.


In our experience, online slots machines with bonus rounds are always a great way to go. Slots bonus rounds can dramatically increase your play time, winnings and fun. Free spins are basically a dream come true, a strange inversion of the no risk no reward maxim that mutates into no risk but huge possible rewards. What could be better.
Take the time to study our slots reviews to get a feel for the different types of bonus rounds available on different slots machines and select a slot that gives you multiple opportunities to win free spins, prize multipliers and bonus rounds. In our experience, betting the right amount at the right time on a multifunction machine with amazing bonus features is the ultimate way to hit it big, just short of hitting the jackpot. Playing a machine with great bonus features is one of the secrets to slots success.


So, you’ve tested the waters, played online slots for free, sussed out the games you like the most and which slots have the best selection of free spins, bonus rounds and added features like multiple wilds, scatter symbols and prize multipliers. Now it’s time to play and win. But one important thing to keep in mind. You have to pace yourself, know when to up the ante when a slot is loose and hot and when to cool it when lady luck is looking the other way. One key strategy is to keep your slots profits separate.

Select your bankroll, an amount you know you can afford to lose. Set the amount of time you want to play and ration your bets accordingly. When you win, put it aside. That way, you’ll have another bankroll for another day and can still keep on playing with what you already know you can afford to lose. This is an excellent strategy for how to build your bankroll.

Having a hot day, profits way up. Great! Put it aside and continue to bet with the bankroll you brought. When it’s gone, you still walk away a winner. If it keeps multiplying, you can breathe easy knowing your penchant for taking greater risks and betting more is justified, as you’re still just playing with your initial bankroll.


Experienced slots players know that paylines make all the difference. Not so with online slots. With online slots the number of paylines can vary greatly, from 10 paylines to 250 paylines, some games even have payline combinations that can reach 1,024 paylines. Multiple paylines mean the chance for multiple wins on the same bet. Picking a lose machine with great bonus features and a substantial number of paylines can dramatically increase your chances of winning on any given bet. When it comes to paylines, one spin can equal multiple wins.
