Online slots with the best free spin features and bonus rounds

Online slots have become incredibly popular in recent years, offering players a fun and accessible way to potentially win big right from their computer or mobile device. One of the key features that make online slots so engaging is the free spins and bonus rounds that many games offer. These provide players with additional chances to win without having to spend more money.


Starburst is likely the most popular online slot with free spin features. This space-themed game by NetEnt is loved for its dazzling graphics, energetic music, and frequent payouts. The star of the show is the Starburst Wilds feature. Whenever a wild symbol lands on the reels, it will expand to cover the entire reel and remain locked in place while a free respin occurs. A reel covered in wilds increases your chances of hitting a big win significantly. You trigger up to two re-spins this way, leading to some very lucrative outcomes.

Gonzo’s quest

This slot by NetEnt takes players on an expedition through the South American jungles with the Spanish conquistador Gonzalo Pizarro. The Avalanche feature is one of the key highlights, causing winning symbols to disappear to reveal new symbols in an avalanche-like effect. It results in multiple wins from just a single spin. Three free fall symbols on the same payline trigger free falls. You’ll get 10 initial free falls and retrigger more during the bonus. With multipliers rising after each consecutive win, the free-fall bonus leads to really huge payouts on this classic slot.


Buffalo by Aristocrat is a classic casino slot that has made its way online. It uses the popular Buffalo animal theme combined with a unique reel setup of 5 reels and 4 symbol positions. The standout feature is the free spin bonus, triggered by getting at least 3 scatter symbols. Eight free games with 4X multipliers, and all your wins pay both ways! Additionally, you retrigger this bonus indefinitely by landing more scatters. With frequent big wins and the potential for unlimited free spins, it’s easy to see why Buffalo remains a go-to slot for many players.

Mega moolah

While Mega Moolah by Microgaming doesn’t have the most interactive bonus features, it more than makes up for it with the ability to pay out truly life-changing jackpots. The เว็บตรงแท้ game is connected to Microgaming’s progressive network, meaning jackpots can grow into the millions before being won. You’ll first need to hit the Jackpot Bonus wheel, which gets triggered randomly. You then spin the wheel divided into 4 progressive jackpots, with the Mega jackpot averaging around $5 million! Even if you don’t hit the mega prize, the Major and Minor jackpots are still worth tens of thousands and make for an exciting bonus round.
