Casino Game Selection

Big Boost Casino houses over 3,500 games from top providers, ensuring there’s something for every player. Navigation is smooth thanks to categories like Pokies, Live Casino, Jackpots, and “New & Trending.”

Online Pokies

New Zealand players will love the variety of pokies, ranging from classic 3-reel fruit machines to modern Megaways and jackpot slots. Popular titles include:

  • Gates of Olympus (Pragmatic Play) – High-volatility slot with multipliers up to 500x.
  • Sweet Bonanza (Pragmatic Play) – Candy-themed tumbling reels with free spins.
  • Dead or Alive 2 (NetEnt) – A cult classic with big win potential.
  • Mega Moolah (Microgaming) – Legendary progressive jackpot slot.

Big Boost Casino sets itself apart with its exclusive Boosted Slots lobby. This dedicated section rotates monthly and showcases hand-picked titles with special enhancements such as higher RTP versions, bonus buy-in options, or boosted multipliers.

It’s a fun feature that keeps the pokies selection dynamic and exciting for returning players, offering more value than the standard slot catalogue you’ll find at most casinos.

Live Casino

The Live Casino lobby, powered by Evolution Gaming and Pragmatic Play Live, delivers everything from blackjack and roulette to popular game shows. Try Lightning Roulette, Monopoly Live, or Crazy Time for interactive fun with real dealers.

Table Games

Beyond the live options, you’ll find digital versions of blackjack, baccarat, roulette, and poker. Big Boost also includes lesser-known favourites like Casino Hold’em, Red Dog, and Sic Bo.
