1) Starburst

  • Released: 2012
  • Developer: NetEnt
  • Reels: 5x3
  • Paylines: 10 (both ways)
  • RTP: 10%
  • Volatility: Medium
  • Welcome Bonus: bet365 Casino bonus code

NetEnt’s Starburst slot arrived in 2012, and it’s remained among the most popular games ever since.

The space-themed slot has faced stiff competition but rarely bettered.

Starburst wilds can appear during the game and expand to fill an entire reel. Plus, the expanded wild triggers a free re-spin. It’s possible to activate up to three free re-spins.

The beauty of Starburst is that you don’t need a free spins round to feel entertained. The re-spin with expanding wilds is enough of a draw on its own.

2) Buffalo Blitz

  • Released: 2016
  • Developer: Playtech
  • Reels: 6x4
  • Paylines: 4,096
  • RTP: 96%
  • Volatility: Medium
  • Welcome Bonus: BetMGM Casino bonus code

Playtech’s Buffalo Blitz is 10 years old, but it still attracts new players with its 4,096-ways-to-win mechanic.

The strong animal theme is perfectly complemented by big gameplay, where you can win up to 100 free spins. Plus, the multiway gameplay means you have more chances to win during your base spins.

3) Bonanza Megaways

BTG’s epic Bonanza Megaways slot is the earliest of the releases that promises up to 117,649 ways to win on each spin.

Each reel may contain up to seven symbols, meaning there are a different number of win lines on every spin.

Additionally, a horizontal reel spins independently and adds symbols to the combinations below.

Want more? Bonanza Megaways includes four progressive jackpots, each triggered randomly during gameplay.

4) Dead or Alive

NetEnt’s Dead or Alive is still (in our opinion) the strongest of their Wild-West-themed slots to date.

There are only nine paylines in play, but a ton of action on every spin.

You trigger 12 free spins by landing 3+ scatters anywhere. Plus, sticky wilds may appear during the round.

You win five bonus free spins if you land a sticky wild on each reel simultaneously. And as a final perk, all your wins double during the free spins round.

NetEnt has a history of high-volatility slots with generous bonus features. No wonder Dead or Alive continues to hit the 'Most Popular Slots' tabs at our recommended casinos.

5) Huff N’ More Puff

How could we finish our top five online casino slots of June 2026 without mentioning Huff N’ More Puff?

Light & Wonder’s three-little-pigs-themed slot was released in 2025, but it’s still proving popular with FanDuel players.

Part of that is down to the fixed jackpots, the biggest of which is worth a cool $5,000.

You can also trigger free spins with giant (and we mean bigger than the big bad wolf) symbols. These can fill an area as big as 3x3 to enhance wins.
