As mentioned, there are a number of top online free slot games available to play that come equipped with bonus rounds, however there might not be any that are better than the ones that can be found in this list below.
Here are the top five online free slots with bonus rounds that have been available to punters over the last few years:
Starburst Online Slot Game Bonus
There is no denying - or even arguing - that Starburst is one of the best free slot games to have ever been made available to play. NetEnt are the creators of this all-time classic and have provided bettors with the chance to win some big money via the bonus features that they have provided.
The main attraction of this Starburst online slot game is the free spins round, which can be triggered when wilds appear. In addition, these special icons also have the ability to expand and fill the reels, thus providing bettors with even more opportunities to win the huge €/£/$50,000 maximum win that is on offer when played.
This free slot has a return to player (RTP) rate of 96.1% and a volatility level that is of a low nature, therefore meaning it is perfect for new slot players as wins can be frequent, albeit rather low in value.
Monopoly Megaways Video Slot Features
Produced and developed by Big Time Gaming and Hasbro - the original creators of the classic board game - Monopoly Megaways features a number of bonus features that can help to boost wins significantly.
With up to 117,649 ways to win, bonus features include a free spins round which is triggerable when a fifth house is added to an owned property or when ‘Chance’ is landed on. There are three other bonus features, including cascades, unlimited win multiplier and the ‘Reel Adventure’ that provides even more chances to win.
There is an RTP rate of 96.5% which is standard and a volatility level that is high, therefore meaning wins can be lucrative when they land as a maximum win amount stands at 14,700x on each free spin taken!
Game of Thrones Slot Bonus Rounds
Another top online slot packed with bonus features that has taken inspiration from a pop culture classic is Microgaming’s Game of Thrones. Just as epic as the TV show proved to be, the game also features a number of epic bonuses, with 5 available!
Included in the five are four different free spins features, with each house represented as a different bonus!
There are two different versions to play, with a 15-payline free slot as well as one that consists of 243 ways to win. Depending on the game chosen, the maximum win is either 5,000x the stake or 20,250x the stake, whilst the RTP is around 95% for both versions.

As is Starburst, Book of Ra online slot is one of the most popular online free slots to have ever been created. The Ancient Egyptian themed game - which is highly popular - has been created and produced by Novomatic and remains a staple of many online slot enthusiast’s go-to titles.
Although it is not as packed as others on this list in regards to bonus rounds, it does feature a cool free spins game that is easy to follow and play, whilst there is a gamble system that can be triggered and used after each winning spin, thus allowing wins to increase by twice the amount when the outcome has been successfully predicted.
Due to the gamble feature, up to 25,000 coins can be won, whilst the RTP rate of 94.26% and a medium volatility level mean wins can be achieved semi-regularly.
