Blueprint Gaming's Diamond Mine Megaways pins its appeal on three things: the Megaways engine's variable reel structure, a high-volatility payout profile, and an RTP of 96.43%. Players who look for games like Diamond Mine Megaways are almost always chasing at least two of those three, and the best alternatives match on all of them.
The eight alternatives here cover the Blueprint Gaming Megaways catalogue directly, plus two cross-studio options that share the gem theme or the Megaways engine. Slots like Diamond Mine Megaways are easiest to identify by studio and mechanic together: theme alone misses the structural point.
Diamond Mine 2 Megaways is Blueprint Gaming's follow-up to the original, carrying the same Megaways engine and diamond-and-gem visual identity. The Megaways count and the way the reel engine breathes during a bonus sequence give this sequel a distinct feel despite sharing the same core formula.
The RTP here is 95%, lower than Diamond Mine Megaways's 96.43%. For players who found the original's Megaways formula compelling and want to continue within the same studio's version of it, this is the most direct path forward: same developer, same mechanic, same theme.
Bison Rising Megaways is built by Blueprint Gaming on the same Megaways foundation as Diamond Mine Megaways: six reels, high volatility, and an RTP of 96.50%. Those three dimensions align more closely with the original than any other game on this list outside the direct sequel, making this the tightest mechanical match for players who care about volatility and theoretical return together.
The max win is verified at 50,000x stake, a figure not available for Diamond Mine Megaways in the confirmed data. The theme is an American wilderness setting rather than gemstones, but the structural skeleton is near-identical to what the original delivers.
Rick and Morty Megaways wraps a Blueprint Gaming Megaways core in a licensed TV theme. The mechanics underneath are consistent with Diamond Mine Megaways: high volatility and an RTP of 96.55%, sitting in the same territory as the original's 96.43%. The max win is verified at 50,000x stake.
The reel count is five here versus six in Diamond Mine Megaways, which narrows the peak ways-to-win count. For players drawn to Blueprint Gaming's high-volatility Megaways formula rather than the gemstone setting, this title delivers that same commitment in a different visual register.
Big Cat King Megaways is a Blueprint Gaming Megaways title with an RTP of 96.5%, placing it very close to Diamond Mine Megaways's 96.43% in theoretical return. The studio and engine are the same; the difference is a wildlife theme and five reels rather than the original's six.
The volatility is rated at 4 and the payline format is all ways. Players who prioritise an almost matching RTP within Blueprint Gaming's Megaways range will find this a natural step sideways, though the reduced reel count changes the upper end of the ways-to-win count.
Almighty Bear Megaways is a six-reel Blueprint Gaming entry in the Megaways format, running all ways. That puts it on the same structural footing as Diamond Mine Megaways in terms of reel count and how the engine counts wins, making it one of the closer Blueprint six-reel alternatives on the list.
The RTP is 95%, lower than Diamond Mine Megaways's 96.43%, and the volatility is rated at 5. The animal theme replaces the gemstone setting, but the Blueprint Megaways framework is consistent throughout.
Big Catch Bass Fishing Megaways is a Blueprint Gaming Megaways game built on the same engine as Diamond Mine Megaways. It runs on five reels with a volatility rating of 4. The fishing theme is a clear departure from the gem-and-diamond setting, and the five-reel layout reduces the maximum ways-to-win count compared to the original's six.
The RTP is 96%, somewhat lower than Diamond Mine Megaways's 96.43%. Players who want to sample other entries in Blueprint Gaming's Megaways range without switching studios will find the mechanic familiar, even if the theme takes a very different direction.
Branded Megaways from Iron Dog Studio runs on six reels in the Megaways format, matching Diamond Mine Megaways's reel count exactly. The gem theme is another point of contact: this is a jewel-symbol game in the same visual category as the original, which makes it one of the few non-Blueprint alternatives with two structural links to the head game.
The RTP is 96% and the volatility is rated at 5. The studio change from Blueprint Gaming to Iron Dog Studio means the Megaways licence implementation differs, but the six-reel gem-themed format makes this a reasonable choice for players looking to extend their session in familiar structural territory.
Aztec Gems Megaways comes from Pragmatic Play rather than Blueprint Gaming and runs on three reels, a significant structural difference from Diamond Mine Megaways's six. The gem theme is the clearest link: this is a jewel-forward game in the same aesthetic category as the original, and the Megaways engine is shared.
The RTP is 96.58% and the volatility is rated at 3, notably lower than Diamond Mine Megaways's high-volatility profile. This title suits players drawn specifically to the gem theme who want a less demanding variance level from the Megaways format, rather than those chasing the original's high-volatility feel.
All eight alternatives share the Megaways mechanic with Diamond Mine Megaways, which is the defining structural choice of the original. The dividing line within that group is studio: six of the eight are Blueprint Gaming titles, meaning the Megaways licence implementation and the general feel of the reel engine are as close to the original as they can be without being the same game.
RTP clusters around the 96% range across most of the list. Bison Rising Megaways at 96.50% and Big Cat King Megaways at 96.5% are nearest to Diamond Mine Megaways's 96.43% among those with a confirmed figure. Rick and Morty Megaways at 96.55% sits in a similar band. Diamond Mine 2 Megaways and Almighty Bear Megaways both come in at 95%, the lowest on the list. Aztec Gems Megaways is the structural outlier: three reels versus six, and a volatility rating of 3, which changes the session feel substantially despite the shared Megaways label and gem theme.
For the closest structural replay, Diamond Mine 2 Megaways is the natural starting point: same studio, same IP, same Megaways engine, same gem theme. If you want the Blueprint Megaways formula with high volatility confirmed and a near-identical RTP, Bison Rising Megaways on six reels is the tightest mechanical match. Rick and Morty Megaways serves the same function, with an RTP of 96.55% and a verified 50,000x max win, in a licensed theme rather than gemstones.
Players working through games like Diamond Mine Megaways methodically should start with Bison Rising Megaways for the nearest Blueprint six-reel comparison, then move to Rick and Morty Megaways for the same high-volatility commitment with a known max-win ceiling. Aztec Gems Megaways and Branded Megaways connect on the gem theme but both involve a studio change and a meaningful structural shift, so treat them as adjacent rather than equivalent.
To qualify as a casino game like Diamond Mine Megaways, a title must first match on the Megaways engine. That is the non-negotiable filter. After that, the ranking logic adds studio (Blueprint Gaming titles score higher because the engine implementation is closest to the original), reel count (six reels match Diamond Mine Megaways's structure), confirmed volatility level (high is the target band), and RTP proximity to 96.43%.
Theme is a secondary signal. Diamond Mine Megaways runs a gem-and-diamond visual, so gem-themed alternatives receive a small adjacency weight. A different theme with matching mechanics ranks above a matching theme on a different engine. Max-win figures are included where verified and omitted where not confirmed, following the same fact-only standard applied throughout this page.

Online slots are games of chance. Every spin is decided by a random number generator, and no system, staking pattern, or "hot" machine changes the odds in your favour. There is no skill or strategy that guarantees a win, and no way to make a game due to pay out. Slots are a form of entertainment, and the cost of that entertainment is the money you stake. Treat them as something you spend on for fun, not as a way to make money or to recover money you have already lost.
Decide what you can comfortably afford to lose before you play, and set that as a firm budget. Licensed operators give you tools to hold yourself to it: deposit limits, loss limits, time-outs, reality-check reminders, and self-exclusion. Turn these on at the start rather than in the heat of a session, when a limit is far easier to set than to respect. Playing within a fixed budget, with limits already in place, is the single most reliable way to keep slots enjoyable.
Watch for the signs that it has stopped being fun: chasing losses to win money back, playing longer or more often than you intended, betting money you cannot spare, or feeling anxious, secretive, or low about how much you are playing. If any of that sounds familiar, take a break and reach out. Free, confidential help and advice are available through GamCare and BeGambleAware, whose support is independent of any operator and available whether you gamble a little or a lot. Asking for help early is a sign of good judgement, not failure. This site and its content are strictly for adults aged 18 and over.
