Aztec Artefacts

Thunderspin's Aztec Artefacts is a video slot that features a 7×7 grid, utilizing cluster pays instead of traditional paylines. Wins occur when groups of at least five matching symbols are adjacent either horizontally or vertically. The base game incorporates an Avalanche mechanic, where winning clusters disappear, allowing new symbols to fall into place, which can lead to additional wins within a single spin. As you collect winning symbols, including wilds, the Mystical Bonus meter fills up; once it reaches 20 symbols, the Mystical Bonus is activated. At this point, one class of regular symbols, either high or low value, is randomly selected, transforming all symbols of that class on the grid into the chosen symbol, enhancing the potential for large clusters. Wild symbols are present in the game, substituting for regular symbols to help form winning clusters, though they do not function as scatters. Landing scatter symbols, represented by books, during the base game triggers free spins, with the number of scatters determining the amount of free spins awarded: three scatters yield 10 free spins, four provide 12, five result in 15, six grant 20, and seven offer 30. In the free spins round, the Mystical Bonus feature activates on every spin without needing to refill the meter. Additionally, an increasing multiplier is associated with cascading wins during free spins, starting at ×2 and rising to ×3, ×5, and up to ×10 with four or more consecutive avalanches. The maximum win achievable in Aztec Artefacts can reach up to 1,000× your stake.
