Thunderfist

Imagine a cross between the Mortal Kombat video game and a Saturday morning cartoon, and you'll have an idea of what's in store for you with Thunderfist, the latest title in NetEnt's wildly varied portfolio. This online slot machine does not require any download, and it can be played on computers, laptops, and Internet-enabled devices such as tablets and smartphones.

The game has five reels and three rows. There are 243 pay lines. The minimum bet is .25 credits per spin. The maximum is 125 credits per spin. You can use the player dashboard to set your bet lines, your coin denomination, choosing the maximum bet, and selecting autoplay for up to 1,000 spins.

Icons include jack, queen, king, and ace, all rendered in rustic bamboo, plus a male gold and tan character with blade hands, a female ninja in royal blue, an elderly master holding a spear, another female ninja in hot pink bearing a bladed fan in each hand, and a modern fighter dressed in red.

The wizard is your wild and can substitute for any icon you need to make a win. He can appear alone or as a stacked wild that takes over an entire reel.

The golden dragon is your scatter. Get at least three and kick off the free spins mode. Three scatters will yield 10 free spins; four rewards you with 15 free spins; and you'll receive 20 free spins for five scatters on the reels. During free spins mode, a random multiplier will be added to your wins. It can be as low as twice your winnings and as high as five times your winnings.
