Diamond Mine Extra Gold Megaways Review

Game Overview

Diamond Mine Extra Gold is Blueprint Gaming's enhanced edition of their original Diamond Mine Megaways slot. Set deep underground in a glittering mine shaft, the game features up to 117,649 ways to win across a 6-reel Megaways grid with a horizontal bonus reel at the top. The Extra Gold upgrade adds the mine cart bonus feature — a random modifier that drops mystery symbols onto the reels, all transforming into the same high-value symbol for potentially massive wins.

The cascading reels mechanic removes winning symbols after each win, allowing new symbols to fall into place. During free spins, each cascade increases a win multiplier with no upper limit — this uncapped multiplier is the primary driver of the game's 10,000x maximum payout. The combination of Megaways, cascades, and unlimited multipliers has made this one of the most popular mining-themed slots among SA players who enjoy high-volatility gameplay.

Key Features

• • Megaways Engine: Each reel displays 2–7 symbols per spin, creating up to 117,649 ways to win. The horizontal bonus reel adds an extra row above reels 2–5.
• • Cascading Wins: Winning symbols explode and new ones fall in. Multiple cascades per spin are common and each one builds momentum toward bigger payouts.
• • Extra Gold Mine Cart: Randomly triggered in the base game, the mine cart rolls across the top reel and drops 2–4 mystery symbols onto the grid, all revealing the same symbol.
• • Unlimited Multiplier Free Spins: 12 free spins triggered by 3+ scatters. Every cascade increases the multiplier by 1x with no cap — long cascade chains can build 20x, 30x, or higher multipliers.
• • Gamble Feature: After any win, gamble for a chance to double your payout up to 5 times.

Free Spins Strategy

The free spins round is where Diamond Mine Extra Gold truly shines. With 12 initial spins and an unlimited multiplier, the key is landing long cascade chains. Each successive cascade in a single spin increases the multiplier by 1x, and this multiplier persists throughout the entire free spins round. By spin 8 or 9, multipliers of 15x-25x are achievable, meaning even modest wins become substantial. Landing 3 more scatters during free spins awards additional spins, extending the multiplier-building opportunity.
