The five-reel, three-row, medium volatility slot has 10 paylines that play both ways (thus creating 20 paylines), there is a free spin bonus, and a “gamble” feature gives you multiple chances to multiply your wins as you try for the maximum 500x payout. Starmania from NextGen Gaming is one of the most prevalent high-RTP slots, turning up at most online casinos with its cool outer-space theme, brightly colored stars, and nifty 3-D animation. With a gothic design featuring vampires, stakes, coffins, and buckets of blood, this low-volatility, five-reel, three-row slot has 25 paylines and features free spins, wilds, scatters, multipliers with bonus games, and a maximum 1,015x payout.

The design mimics an old-school fruit machine (doubled up with the Supermeter game), and Mega Joker offers a 2000x maximum payout.īlood Suckers is another favorite high RTP slot from NetEnt that has been around for many years. Though it’s a relatively simple game with just three reels and three rows, Mega Joker is a famous and beloved high-volatility slot thanks largely to its eye-popping 99% RTP, bonus Supermeter game, and progressive jackpot. Mega Joker from NetEnt has been around for more than a decade.
