The Best Slots on Oppa888 with A Free Spin Bonus

Is there anything better while playing slots than being rewarded with a free spin bonus? Apart from winning the real cash prizes of course, but every free spin bonus comes with more opportunities to do just that!

Every video slot game has different paylines, symbols, and special features that are triggered by various factors as well. However, some of the features that you may see more often include Wild symbols (these can replace any other symbol), a Double bonus game (usually a flip a coin or guess the card color game that will allow you to potentially double your current win - or lose it all), and of course, a Free Spin Bonus (rewards a number of free spins when triggered).

A free spin bonus usually operates similarly across all slot games, in that players receive a specific number of extra spins without having to spend a cent! So, at no cost to the player, the reels will continue to spin and reward prizes until the number of free spins rewarded has been reached. In some cases, additional bonuses are available during the free spins as well.

Below are some of the most entertaining and popular slot games available on Oppa888 that reward a fun free spin bonus! 

1. Hitman Online Slot (Microgaming)

Microgaming brings this video game series and Hollywood action movie to life with Hitman Online Slot – though sadly there’s no Timothy Olyphant to grace the game screen. Instead, players are met with a 5x3 reel field and 15 paylines. In keeping with the hitman, contract killer theme, Hitman Online Slot has several bonuses involving “targets” to kill and secret organization insignias, with surprise cash amounts based on players’ choices. 

When it comes to the free spin bonus, it’s triggered with at least 3 of the special “18” bonus symbol appearing anywhere on the reels. The maximum number of free spins rewarded is 18 and immediately comes with a 2x multiplier on all wins! Although free spins cannot be retriggered, other bonus features and the Expanding Wild can apply during free spins.

2. Reel Desire (Yggdrasil)

Players looking for a fun sot game to play on demo mode can also check out Yggdrasil’s Reel Desire, which features a whopping 1,024 ways to win! The high number of paylines is because across the games 5 columns and 4 rows, winnings are rewarded as long as at least 3 identical symbols land consecutively from the leftmost reel – regardless of their position! Reel Desire also has a Double Wild and Reel Desire feature, as well as the Double Mode Free Spin.

The Free Spin Bonus is triggered when at least 3 free spin symbols appear consecutively and rewards 10 free spins; 4 symbols rewards an additional x50 of your bet; 5 symbols gives x500 of your bet! Before entering the bonus spins, the player can choose between two modes: Multiplier and Sticky Wild. In Multiplier mode, the free spins start with a x1 multiplier and increase with every winning spin. In Sticky Wild mode, all Wild symbols that appear remain stuck on the reels for the duration of the bonus.

3. Christmas Carol Megaways (Pragmatic Play)

Christmas Carol Megaways is definitely a slot game for the history books! It truly brings the classic story to life with its symbols, backdrop, and even with the music. It may be a seasonal-themed slot game, but even if you play it outside of the Christmas season, the large cash prizes and super fun bonus games will make every day feel like Christmas. It has 6 columns and 4 rows (plus a bonus top row over reels 2 to 5), and a unique Tumble feature wherein winning symbols disappear after being paid out and new symbols drop in their place, rewarding more wins until no new ones apply!

The pocket watch is the Scatter symbol of which 4 or more appearing anywhere triggers the Free Spin Bonus. Depending on the number of Scatters that appear, players can choose the number of spins and the win multiplier they’d like to start with - the higher the multiplier, the fewer the free spins. Alternatively, they can have the game randomize this for them.

4. Mighty Medusa (Habanero)

Greek mythology enthusiasts are going to love this one from Habanero as Mighty Medusa centers its theme on the mighty Gorgon monster Medusa. It even features a bonus game called the Medusa Duel Feature, wherein a Soldier symbol next to the Wild Medusa symbol will cause another Wild symbol to appear randomly on the reels!

The snake Scatter symbol is what players need to watch out for to trigger the Free Spin Bonus; when anywhere between 3 to 6 of these symbols appears anywhere on the reels, players are rewarded with 7, 12, 25, and 100 free spins, respectively. That’s right, you may have a chance to win big with 100 extra free spins! What’s more, a 2x2 size Wild Medusa symbol is placed in the middle of the reels and remains in place throughout the duration of the free spins.

5. Back to the 70s (Wazdan)

Bright lights, big hair, and bellbottom jeans – Wazdan truly takes its players back several decades with Back to the 70s, the retro-themed video slot game. Even the game symbols are reminiscent of the era, with platform shoes, cassette tapes, vinyl records, and disco lights permeating the 5x3 game reels. 

Unlike most other slot games, Back to the 70s uses just (1) symbol for both its Wild and Free Spin Bonus trigger: the Disco Ball Scatter. When part of a payline, the Scatter replaces any symbol in order to pay out the corresponding wins. As a Free Spins symbol, having at least 3 appear on the reels will reward 10 more spins! Additionally, before the free spins start, the player can choose (1) bonus symbol which may expand to fill the entire reel for the duration of the free spin bonus! Scoring an additional (3) Scatter symbol during the bonus can retrigger it, too!

So head to Oppa888 today to play Back to the 70s!

6. Three Star God (Simple Play)

There’s always something about Chinese-themed video slot games that makes us feel that extra bit of luck while playing. Perhaps it’s the red and gold theme, or the visuals of gold and treasure chests, much like you’ll see in Simple Play’s Three Star God. With 5 reels and 3 rows, there are no set paylines for wins - all you have to do is land three identical symbols consecutively starting from the leftmost reel - and that means there’s 243 ways to win.

The Scatter symbol that will trigger the free spin bonus is shaped like a Chinese character; 3 symbols also give a x3 bet reward, 4 symbols a x10 bet reward, and 5 symbols a x20 bet reward! Upon triggering the free spins, players can choose one of three options: Reel 2 expands into a Wild symbol with 6 free spins, Reel 3 becomes a Wild symbol reel with 9 free spins, or Reel 4 expands into a Wild with 12 free spins! Additionally with each spin, another reel may (or may not) turn into another Wild at random.

7. Jolly Roger 2 (Play n’ Go)

Pirates are known for hunting for and looting gold and treasure, so it’s the perfect theme for a slot game that provides so many chances for players to do the same! On the surface, Play n’ Go’s Jolly Roger 2 seems like your run-of-the-mill, 5x3 reel slot with symbols like a pirate, skull and crossbones flag, and various treasures to fit the theme. However, it also hides a Compass multiplier of up to x10, and the Scatter symbol hides not just one but four bonus games! Landing 3 Scatters will trigger the Bonus Quest Feature, wherein players will pick pieces off the board - match 3 and they’ll move onto the bonus game indicated.

Of these four bonus games, two involve a free spin bonus that is sure to grab your attention. The first is the Bottle of Rum free spin, where a Compass multiplier may be activated and the Bottles of Rum at the bottom may turn the entire reel Wild during the free spins! The second is the Battle Free Spins – battle against Privateers and Merchants by landing the higher number of coins, and the bonus only ends when you’ve lost three times. Even then, each loss activates one free spin with a specific reward: stacked Wilds, changing symbols to reward wins, or even synchronized symbols across three wheels!
