Max Elements Slot by Yggdrasil Gaming

This one came out of a partnership between Yggdrasil and CasinoGrounds, which is unusual context to flag, but it explains why the feature stack runs deeper than a typical GigaBlox release. Four Feature Runes, transforming Mystery Stones, two free spin modes you actually pick between, a Super FS upgrade path, and a multiplier ladder that escalates the more it climbs. That is a lot to fit on a 5x6 grid, and the game doesn't apologise for it.

The base layer is pay-anywhere from 8 of a kind, with cascading Avalanche drops after every win. GigaBlox is the signature: oversized 2x2, 3x3, 4x4, or 5x5 symbol blocks that count as N times N copies, so a 5x5 block alone counts as 25 matching icons - close to the top paytable rows on its own. Mystery Stones land in the same sizes, persist through the entire Avalanche session, and reroll into a different paying symbol every cascade. They are the closest thing here to a sticky wild, except the symbol they become changes underneath you.

The four Runes are where the real branching lives. Transform converts low-pay symbols into a high or into Mystery Stones. Delete wipes any paying symbol type with fewer than 6 copies on the grid. Multiply doubles the global multiplier as a 1x1 or triples it as a 2x2 GigaBlox. Add tacks on +1 to +4 from a 1x1, or up to +100 from a GigaBlox version. In the base game that multiplier resets when an Avalanche session ends. In Free Spins it persists.

Three Scatters trigger 6 free spins, and you choose: Mystery Stone FS guarantees at least one 2x2-or-bigger Mystery Stone every spin, or Runic FS guarantees a Rune. Land a Super Scatter alongside two normal Scatters in the base game and you skip past the choice into 8 Super Free Spins, which guarantee both. The multiplier persists the whole round, gaining +1 per win, then +2 once it crosses x10, +3 past x30, +4 past x60, +5 past x100, with no cap. Each threshold also tacks on a free spin.

Visually the elemental tiles - flame, water drop, leaf, cloud, stone - sit in carved frames against a mossy emerald forest temple, with two giant owl-faced statues spilling waterfalls beside the reels. Max himself, the bald wizard with the white beard and gold circlet, shows up as a 3x3 GigaBlox face. Buy Bonus options run 100x for Free Spins or 300x for the Super tier; Golden Bet at 3x or 6x boosts trigger odds without buying outright.
