Bonanza Megaways Slot Review — RTP, Volatility & Where to Play

Bonanza Megaways is the slot that changed the industry. Big Time Gaming introduced the Megaways mechanic with this 2016 release, and the consequence was an entire genre: today, hundreds of Megaways-licensed titles from dozens of studios owe their existence to what BTG built in Bonanza. Playing the original in 2024 is a genuinely interesting experience — partly as a mechanical curiosity, partly because the game itself still holds up.

The mechanic: six reels with a variable number of rows per reel on each spin (2 to 7), generating up to 117,649 ways to win per spin. A horizontal symbol stream runs above the six reels, adding a seventh active position per reel for every spin. Wins pay on any symbol combination appearing left to right across adjacent reels, regardless of vertical position. Every spin is structurally different from the last because the reel heights are randomised.

Cascades remove winning symbols and drop replacements. Four scatter symbols in the top symbol stream trigger the Free Spins round with an unlimited win multiplier: the multiplier starts at 1x and increments by 1x with each cascade. Retriggering by landing more scatters during free spins adds 5 more spins without resetting the multiplier. A long retrigger chain with the multiplier reaching 20x, 30x, 50x+ applied to a full 117,649-ways board is the path to the 26,000x ceiling — and unlike many stated maximums, this game's multiplier is mechanically uncapped, meaning theoretical wins beyond the recorded maximum are possible.

The base game is genuinely entertaining. The variable reel heights, top symbol stream, and cascade mechanics create a session texture that static-reel slots lack. Individual base game wins rarely exceed 10x-20x stake, but the visual dynamism keeps engagement high between free spin triggers.

The 96% RTP is the most legitimate criticism in 2024. When Bonanza was released, 96% was normal — today, players can access Megaways titles with 96.5%-97% RTP using the same mechanic. The original does not have a bonus buy, which modern players find limiting.

Bonanza remains worth playing for the session quality and mechanical authenticity. As a pure RTP comparison it has been outclassed, but few successors replicate the specific feel of the original.
