With the massive library of slot games offered by most online casinos, finding the right one to play may seem daunting.
Especially considering the slot you want to play will ideally be the one that is about to pay out big.
While there are many guides to finding a winning slot, these require no small amount of effort. From looking at RTP (return to player) to seeing which progressive slot has the highest jackpot, your big win may be taken by somebody else before you even get to play.
We’ve looked up all the slot machines most likely to hit to make life easier. These are based on the RTP of each slot, the developers’ average RTP, and the popularity of each game.
So, without wasting any more time, let’s dive into the top slots to play.
Ugga Bugga – Playtech
Released in 2013, this slot certainly cannot be considered new. However, it still holds one of the highest RTP rates of any online slot. This RTP is a crazy 99.07% regardless of how much your bet amount is.
The game features an entirely different concept from regular slots. It has ten lines of symbols across three reels.
To accommodate all ten lines, these reels are doubled on the screen (with five lines on one half and the other five next to it). There are also only ten pay lines in the game.
The strangest part of this game is that each bet takes place in two parts. When pressing spin, only the symbols in the first three-reel section will spin. You will then have the option to hold selected symbols, which will also be held in the second three-reel section.
After selecting your holds, you can spin again, which will cause all remaining reels to spin.
This slot also features wilds (that can be held like any other symbol) and a scatter that pays out whether or not it falls on a pay line.
This makes the game even more unique than others and can win you even more.
Book of 99 – Relax Gaming
Developed by one of the biggest names in the industry, Relax Gaming, this game provides a fun way to win big.
The game offers an excellent RTP of 99%, meaning it pays almost all the money it receives.
The game consists of a standard 5×3 configuration with ten pay lines that you can win from. There is no interactive bonus that you can win.
However, the game does feature a book symbol that acts as both a wild (for all symbols), and a scatter that triggers ten free spins if you get three on a single screen.
Aside from triggering free spins by getting three scatter symbols, the game also has a counter on the left. Each time a book scatter appears on screen, it is added to this counter.
Reaching 99 will automatically trigger free spins regardless of whether or not you’ve received three on a single screen.
A random symbol will be selected as an expanding wild during the free spins. Should three of the chosen symbols appear on screen, they will expand to fill the entire reel. This is a great way to get impressive payouts (up to 5,000 times your bet if playing on the maximum bet).
Getting three more book scatters during your free spins will also create a retrigger—giving you ten additional spins. Getting enough retriggers could have you winning massively without spending a cent.
Mega Joker – NetEnt
Released in 2011 by NetEnt, Mega Joker may be missing some of the most popular features of modern slots. These include free spins and any form of a bonus round.
However, what the slot offers will be enough to entice you to look for casino slot sites to play it on.
The game features a standard three-reel configuration with five rows. However, it looks nothing like most slots. Instead, NetEnt designed the game to look like a traditional slot machine, including lights, sounds, and backgrounds.
What stands out more than the game’s design is that it hosts a progressive jackpot. This means that the jackpot grows each time any player makes a bet and can lead to some truly impressive prizes.
This fact is made even better by the RTP of the game, which is 99%.
This slot also features something called the Super Meter Game. This mode can be voluntarily enabled when you make a win and lets you enter into a new game mode.
In this mode, your bet amounts will cost you more. However, the prizes that you can win will surely have you smiling.
Jokerizer – YGGDRASIL
First available in 2016, this great game by YGGDRASIL lets you clown around while winning big. The game features a 3×5 reel combination and doesn’t feature any bonus rounds, free spins, or even wilds. However, it still has more than enough to help you win big.
The first thing that makes this game worth playing is the RTP. This is listed up to 98%, making it worth the risk of playing.
However, the game’s two extra features make this slot stand out. The first of these is the Jokerizer Mode.

Winning any amount on any of the ten pay lines activates the Jokerizer Mode. During this game mode, all bets are placed at maximum bet. However, to compensate for this, the odds of winning drastically increase, leading to bigger prizes.
During this mode, you can activate the next feature, Mystery Win. Getting two or more clown symbols will grant you a mystery prize—which is usually a great deal of winning. Getting three clowns in the right place will give you a mystery prize of 6,000 credits.
You can opt to leave Jokerizer mode by simply clicking on Cash Out. However, with the higher chance of winning and the great Mystery Win feature, we don’t see it likely that you’d want to exit the mode any time soon.
