Mammoth Gold Megaways has an unusual 6x7 grid layout. It has a megaways win mechanism offering 117,649 ways to win and a tumble feature. That means that winning symbols will be removed from the board after you win and will then be replaced by new ones. This gives you more chances to win but does make the game high volatility. It has an RTP rate of 96.03%, which sits squarely in the average 96% to 96.5% range for most online slots.
The lower-paying symbols include diamonds, clubs, hearts, spades, dodos, and bears. A winning combination of 6 with one of these pays 0.5x-0.75x the bet. The higher-paying symbols consist of boars, wolves, sabre-toothed tigers, and mammoths. Six-of-a-kind with these will pay 1x-5x the bet. The Wild symbol is a volcano and substitutes for all other paying symbols. Landing 3 or more uncut gems (Scatter symbols) triggers the Free Spins feature.
The gameplay doesn’t undergo much of a change during the bonus mode. Instead, existing mechanics are enhanced further, pushing you closer to the promise of reaching that 10,000x maximum win. As such, the wild multiplier doesn’t reset at all during free spins. The metre continues to increase with every wild multiplier that lands and its value is applied to any wins made during free spins. Tumble features will also add +1 to the multiplier metre.
You can even add more free spins by landing additional scatter symbols. 2, 3, 4, 5 or 6 symbols will add 1, 2, 3, 4 or 6 symbols, respectively.
