Bonanza Megaways Review 2026: The Original Megaways Slot — RTP, Mechanics, and Max Win

Bonanza Megaways, released by Big Time Gaming in 2016, is one of the most significant slots in industry history. It introduced the Megaways mechanic that has since been licensed to over 100 games across dozens of studios — fundamentally changing what slot games can offer in terms of win ways and variance.

How Bonanza's Megaways works

Bonanza uses a 6-reel layout where each reel displays between 2 and 7 symbols per spin. The maximum ways to win = 7 × 7 × 7 × 7 × 7 × 7 = 117,649. A horizontal conveyor belt runs above the main reels, displaying 4 additional symbols that contribute to wins — these can only form part of a combination when the same symbol appears on the reel below.

Wins pay on consecutive reels from left to right on any position — there are no fixed paylines. When a win occurs, winning symbols are removed and new ones fall in from above (the cascade or reaction mechanic), potentially creating chain wins from a single paid spin.

The free spins bonus

Landing 4+ scatter symbols (labelled GOLD) triggers 12 free spins. During the bonus: each cascade increases the multiplier by 1 (starting at 1×, no cap). Each additional scatter landed during free spins awards +5 more free spins. The combination of unlimited multiplier and cascading wins creates the potential for enormous payouts — the theoretical 10,000× max win requires a long cascade chain with a high multiplier running simultaneously.

RTP and real expectations

Bonanza's RTP is 96%, with the vast majority of the expected return concentrated in the free spins bonus. This means variance is very high even by high-volatility standards. Many sessions will end with a loss; a small number will hit a feature with a long cascade chain and produce hundreds or thousands of times the stake.

Comparison to licensed Megaways games

Bonanza remains one of the best Megaways implementations despite its age. The conveyor belt is unique to BTG's own games. Comparable Megaways titles like Extra Chilli (BTG), White Rabbit (BTG), and Primal Megaways (Blueprint) all offer interesting variations — but players looking for the definitive Megaways experience should start with Bonanza.
