Bonanza Megaways vs Diamond Mine Megaways — 2026 Comparison

Bonanza Megaways wins over Diamond Mine Megaways on max win potential (26,000× stake vs 10,000× stake — a 16,000× gap that is the most decisive difference between these two mining-themed Megaways slots). Diamond Mine Megaways leads on published RTP at 96 for UK players.

Side-by-Side Specs

These two titles are often confused because both run 117,649 ways on a mining theme, but the specs tell a different story across provider, max win, and release year.

How Bonanza Megaways Plays

Bonanza Megaways is the slot that popularised the Megaways mechanic when Big Time Gaming released it in 2016. The grid uses a cascading-reel engine — winning symbols are removed and replaced, allowing chains of consecutive wins from a single spin. A horizontal conveyor reel above the main grid adds an extra symbol to each cascade sequence. The free-spins round awards an unlimited multiplier that increments with every cascade, which is the primary driver of the 26,000× maximum win. In our testing, the cascading sequence could reset several times before a free-spin trigger materialised, which reflects the high-volatility profile accurately. For a full mechanic breakdown, see Bonanza Megaways review.

How Diamond Mine Megaways Plays

Diamond Mine Megaways is Blueprint Gaming's 2020 entry into the mining Megaways category. It shares the 117,649-payline Megaways format but wraps it in Blueprint's own bonus architecture, which includes a free-spins round with a multiplier trail. The public paytable does not disclose the exact scatter count required to trigger free spins, so we will not speculate. The maximum win is capped at 10,000× stake. In our testing sessions the base game delivered steadier, shorter win bursts compared to Bonanza Megaways, though volatility is listed as N/A in the published data. See Diamond Mine Megaways for a deeper look at the bonus structure.

Which Should You Play?

Play Bonanza Megaways if...
