Games Global partner Alchemy Gaming showcases their impressive features in their latest game, Anvil and Ore. One notable feature is the Echo Rolls, which provides mystery wins after a Rolling Reels sequence. As players progress up the Upsizer Meter, their bonus rounds become more lucrative, with the Max Upsizer level guaranteed every 5 triggers. Players can also pay to upgrade the feature, which includes a progressive multiplier and Echo Spins. With a potential of 5,000x, Anvil and Ore stands out among mining slots. The game includes Wild symbols that double the payout of the Dwarf symbol and help complete winning combinations. The Anvil and Ore Slot also features the randomly triggered Echo Roll feature, which guarantees a win by replacing empty positions with matching pay symbols or wilds. The Upsizer Meter can be upgraded by collecting Upsizer Coins, determining the rewards for the next bonus round. Free spins are awarded based on the Upsizer level, with a win multiplier that increases with more free spins. Additional scatters during the bonus round grant extra spins and increase the win multiplier. The bonus round concludes with the Upsizer Wheel, adding more coins to the meter for the next round. The Anvil and Ore Bonus Buy menu allows players to purchase a random Upsizer level or pay for the Max Upsizer level feature. While the mining visuals are impressive, some symbols may not have the desired impact. Overall, Anvil and Ore offers a solid gaming experience, with a focus on upgrading the Upsizer Meter for better rewards. The Echo Rolls and potential 5,000x payout make it an attractive choice for mining slot enthusiasts.
