The Best Online Slots

Whilst many people decide which slot to play based on the theme, special features or promotional offers, the savvy gamblers steer towards slots with the highest RTP. The house edge of online slot machines can vary widely, and it stands to reason that the lower the house edge, the better your chances of winning.

Online slots are also legal. In October 2017, Gov. Tom Wolf signed bill H 271 into law. This set up the process for licensing online casinos in Pennsylvania. Category 1-3 casinos all had an option to obtain an online slot license for $4 million or as part of a three license package costing $10 million.

The return to player percentage of a game is measured over thousands of game rounds, and it stands to reason that the higher the RTP, the better the deal for the player. With this in mind, I have decided to create a list of the 10 online slots with the highest RTP.

#10 Jack Hammer 2 (NetEnt) – 97.1% RTP

Jack Hammer 2 is the first of many NetEnt slots to make this top 10 list. This entertaining slot has a crime and adventure theme, captured in a comic book style. There are an impressive 99 bet lines in this game, providing plenty of opportunities to win. It also boasts a variety of interesting features that make the game exciting to play, whilst creating chances to win. The Sticky Win feature sees any winning symbol combinations held in place for a free re-spin, and they continue until no new wins are created. There is also a free spin feature, where you get up to 20 free plays, where all wins are doubled and extra wilds randomly land on the reels. Jack Hammer 2 has a player-friendly RTP of 97.1%

#9 Simsalabim (NetEnt) – 97.5% RTP

This magical themed slot recreates all the excitement of a magic show. The stage is set, with symbols such as a magician’s wand and top hat, a caged dove and a Houdini-style chained chest. The hypnotist is wild, helping to complete winning symbol combinations. When you play Simsalabim, keep your eyes peeled for 3 bunny rabbit symbols on the first 3 reels. These trigger the bonus game, where you pull rabbits from the hats to reveal cash prizes of up to 50500 coins.

Here, you get 10 Sin Spins where you can pocket some juicy rewards. With so many cool features and a high RTP of 97.6%, this is one hell of a slot!

#6 Kings of Chicago (NetEnt) – 97.8% RTP

Kings of Chicago mixes the best elements of a video slot with classic poker. The game is played with a deck of cards, which is shuffled before each round. Unlike normal slot machines, where payouts are made for matching symbols across paylines, in this slot, you win if you have a poker hand on one of the five paylines. The game includes a joker, which substitutes for all cards. Plus, the scatter label can randomly appear on any card. Get 3 or more and free deals, the equivalent of free spins are triggered. You can bag up to 30 free deals in the special feature and all wins are doubled. This innovative slot machine provides a unique twist on what you expect from a video slot, and boasts an impressive RTP of 97.8%.

#5 Starmania (NextGen) – 97.87% RTP

Trigger the bonus and you will find yourself in an ancient burial chamber, filled with coffins. Open the coffins to slay vampires, earning coin wins with each creature you defeat.

#3 1429 Uncharted Seas (Thunderkick) – 98.6% RTP

The

This video slot from Thunderkick is visually stunning.

#2 Jackpot 6000 (NetEnt) – Up to 98.8% RTP

Jackpot 6000 is a thrilling classic slot machine from NetEnt with a real old-school vibe. You can play with up to 5 paylines active, betting between 1 and 10 coins per spin. It is highly recommended to play with the maximum bet of 10 coins however, as this creates the possibility of triggering Supermeter mode. In this game mode, you can win a mystery prize of between 10 – 6000 coins when just 2 joker symbols land anywhere on the reels. Also, getting 3 jokers on a payline in Supermeter mode guarantees a jackpot payout of 6000 coins. When you play Jackpot 6000 with 1 – 8 coins, the RTP is a paltry 74.9% – 79.2%. Yet with 10 coins in play, the RTP ranges from 95.1% – 98.8%. The variance is because Supermeter mode is skill based, so you can directly impact the outcome.

#1 Mega Joker (NetEnt) – Up to 99% RTP

Whilst Jackpot 6000 boasts an extremely high RTP, it is just beaten to the top spot by another NetEnt classic slot; Mega Joker. Bet with just 1 coin and the RTP is an underwhelming 76.9%. Yet on the other hand, a max bet of 10 coins elevates the RTP to between 89.1% – 99%. Furthermore, it provides bigger payouts and the Supermeter mode. In Supermeter mode, you need to choose the bet level and the optimum level at which to collect your winnings. It is this element of skill which can increase the RTP. The skill component, retro style and engaging gameplay make Mega Joker a firm favourite with players.
