Bonanza by Big Time Gaming Overview
Bonanza helped define the Megaways era when it launched in 2016, and it is still a flagship title for Kiwi players. The engine randomises reel heights on every spin, creating thousands of possible symbol combinations, frequent cascades, and a brisk tempo that rewards momentum. The theme drops you into a laid-back mountain mining site. Carts deliver extra symbols across the top, and a water mill turns beside the reels, while gemstone symbols and dynamite wilds anchor the mining vibe.

Megaways replaces traditional paylines with variable ways to win. Each reel can show between 2 and 7 symbols, and the number of active ways can reach 117,649, depending on the reel heights on that spin. Wins trigger cascading reactions that remove winning symbols so new ones drop into place. This cascading mechanic is a core part of Bonanza’s rhythm, especially during the bonus.
What is Bonanza Slot?
Released by Big Time Gaming, Bonanza blends straightforward rules with a deep payout flow. The base game sets up bigger hits by chaining reactions, and the free spins turn that pace into a proper run with an unlimited progressive multiplier. It is widely available across both established and new online casinos, and many players still regard it as Big Time Gaming’s signature game.
The presentation fits the mining theme neatly. Reels sit in a rocky hillside with a track above them that moves mine carts from left to right, dropping extra symbols onto the middle reels. The premium symbols are coloured gemstones, while card ranks cover the lows. A dynamite wild can land to complete wins, and the G, O, L, D letters are scatters that can unlock the bonus. The audiovisuals are understated and tuned for smooth performance on mobile and desktop.
How to play Bonanza Slot
Open the paytable from the three-bar icon in the bottom left to see symbol values, rules, and bonus details. Set your stake on the control panel, with betting options from 0.20 to 20 coins per spin, a range that suits low to mid-stakes players. You can spin manually or use autoplay if it is available in your region, and you can set optional stop limits where supported.
Wins pay when matching symbols land from left to right on adjacent reels, and the number of ways changes each spin. After every win, cascading reactions remove the winning symbols and new ones drop in, giving you extra chances without placing another bet. The dynamite symbol is wild and substitutes for all symbols except the scatter letters. Four gemstone premiums can deliver standout hits, and landing six of the top-paying gem in a single way pays 50 times your stake. The advertised maximum win can climb to around 12,000 times your wager when the multiplier ramps up in free spins.
For a quick feel, give it a whirl at the minimum bet and watch how the reactions stack. A single base spin might produce three or four consecutive cascades, which is often how medium wins land even before the bonus triggers.
Tip
Volatility runs high, so results can swing a bit. If you are planning to chase the free spins, pick a stake that lets you settle in for a longer session without stress. In Aotearoa, stick to reputable NZ-facing casinos and make use of safer gambling tools like time-outs or deposit limits if you need a breather, as encouraged by the Department of Internal Affairs.
Bonanza Slot free spins
You trigger the free spins by landing the four scatter letters that spell GOLD in the base game. This grants 12 free spins. Each additional scatter beyond those four on the triggering spin adds 5 more free spins, setting you up for a stronger start.
The bonus is defined by an unlimited win multiplier that increases by 1 after every cascading reaction and does not reset until the feature ends. This is where Bonanza can really snowball. A small win can trigger several reactions, each step nudging the multiplier higher so that even modest line hits can grow into meaningful payouts later in the round.
During free spins, extra scatters can land in the mine carts above the middle reels to add more spins:
- 3 scatters, 5 extra free spins
- 4 scatters, 10 extra free spins
Combining cascading reactions, the unlimited multiplier, and retriggers, Bonanza’s bonus can be extremely potent. It can also be hard to hit consistently, which is why bankroll management matters. If you enjoy features that build momentum, this online pokie really delivers when it catches fire.
