With a huge variety of online slot games available, many casino players have started to be more analytical when deciding what to play. Rather than being drawn in by the flashing lights, experienced players are now more likely to look for slot games that have special features built-in to the gameplay. One of the most popular is the free spins bonus feature.
A free spins bonus feature is an in-game reward that’s triggered by the slot’s gameplay. When activated, it opens up a special round where players spin the slot without using their own money to bet. This feature is not to be confused with free spins that casinos offer new players as an incentive to join their site. In this case, the free spins are awarded by the casino, rather than being won through any gameplay.
Despite more and more players turning to mobile casinos these days, a few older slot games are not compatible for smartphones and tablets. That’s because they were originally developed using older technologies and have not (yet) been upgraded. Therefore, to avoid any kind of disappointment with compatibility, we’ve picked out the top 5 slot games with a free spins bonus feature that you can play on mobile.
Doom of Dead
How many free spins are possible? Unlimited!
Cat Wilde and the Doom of Dead is a high volatility slot which has an RTP of 96.45%. In this 2020 release from Play’n GO, they’ve brought back the much-loved expanding Wild symbol, especially for this Egyptian-themed game!
How to activate the slot’s free spins bonus feature – When three scatter symbols appear on the reels, you will start the bonus round with 10 rounds. If you land more scatter symbols during this round, more rounds will be added. This can technically continue an unlimited number of times.
Artemis vs Medusa
How many free spins are possible? Unlimited!
Play as the protagonist character Artemis as you do battle with Medusa. This Quickspin creation was released in 2020 and has an RTP of 96.1%. It has a slightly different structure than usual with 5 reels, 4 rows and 1024 ways to win.
How to activate the slot’s free spins bonus feature – You need to get three scatter symbols on the second, third, or fourth reels for this round to be triggered. Every time an Artemis symbol appears, Monster symbols will be added/removed from a Monster Meter. You will receive a bounty when Monster symbols are removed. The bonus round will continue until either the meter exceeds 15 monster symbols or if you kill all the enemies.
Samurai Split
How many free spins are possible? 480
In November 2017, NextGen Gaming released Samurai Split. The game focuses on the random possibility that the Samurai could, on any spin, split the winning symbols in half to increase your payout. It boasts an RTP of 95.41%, with the classic structure of 5×3 reels and 25 paylines.
How to activate the slot’s free spins bonus feature – If you land three, four, or five Samurai banner symbols in the main game, you’ll activate five, 10, or 15 rounds respectively. However, if you manage to land five banner symbols which are all split by the Samurai, you’ll get a massive 480 to really try and hammer home the wins!
Siberian Storm

Siberian Storm was released many years ago by IGT to much acclaim. In 2017, the online version was given an update so it could be played on mobile devices. It features 720 paylines that win both ways, with a hexagonal structure making the gameplay slightly different.
How to activate the slot’s free spins bonus feature – Get five Tiger’s Eye bonus symbols across five consecutive reels to fire up the special round. You will be given 8 rounds at first. If you manage to land five more Tiger’s Eyes bonus symbols across the five reels, this will give you extra rounds. You can repeat this up until the maximum number.
