Bonanza Megaways from Big Time Gaming launched in 2016 and is the original slot that introduced the Megaways mechanic to the industry. The mining-themed Megaways progenitor has become the most historically significant slot of the past decade — every subsequent Megaways title from every provider traces back to the mechanical template Bonanza established.
The Megaways engine in its original implementation produces variable reel heights from 2 to 7 symbols per reel across the 6-reel grid plus a horizontal carriage reel above reels 2-5 that contributes additional symbols. The total ways to win vary from 64 to 117,649 per spin. The carriage reel mechanic — unique to Bonanza among modern Megaways titles — creates specific win pattern possibilities that subsequent Megaways slots have not replicated.
The bonus round uses the scatter-based free spins trigger through G-O-L-D symbols. Collecting G, O, L, D scatters triggers free spins with 12 rounds initially. During free spins, cascading wins build an unlimited multiplier that increases with each consecutive cascade. Extended bonus rounds with favourable cascade chains produce the slot's 12,000x maximum win potential.
RTP is 96.00% theoretical at fixed single configuration. Big Time Gaming maintains fixed-RTP deployment across all licensed casinos. Every UKGC-licensed casino carrying BTG deploys Bonanza Megaways at exactly 96.00%. The deployed RTP matches theoretical — eliminating tier variation concerns that affect variable-RTP alternatives.
The 96.00% theoretical is modest compared to BTG's higher-RTP titles (White Rabbit at 97.39%, Extra Chilli at 96.82%). Bonanza sits at the lower end of the BTG portfolio in pure RTP terms. However, the fixed-RTP deployment provides advantages over variable-RTP competitors.
Volatility is high. The Megaways engine's variable ways count combined with unlimited multiplier progression during free spins produces wide variance. The 12,000x max win is modest compared to extreme-variance alternatives but reflects the slot's 2016-era mathematical approach.
Feature Drop bonus buy was added in a 2019 update at 100x stake. Feature Drop RTP matches base game at 96.00%.
For UK 2026 players choosing between BTG Megaways options, Bonanza offers the historical foundation and carriage reel uniqueness. White Rabbit offers substantially higher RTP (97.39%) and Extra Chilli offers middle-ground RTP (96.82%). Each has fixed-RTP deployment. Selection depends on mechanical and thematic preferences.
Variable reel sizes create up to 117,649 ways to win per spin.

Spell out G-O-L-D across the reels to trigger free spins.
