Atlantis Crush Slot by Relax Gaming

Atlantis Crush splits its 5x5 grid into two zones, and once you understand the split everything else clicks. The bottom three rows hold the paying symbols and the lone Wild. The top two rows hold nothing but Block symbols, stone tiles that never drop into the playable area below. Wins form by scatter pays, four or more matching symbols anywhere across the bottom rows, then those symbols clear and new ones cascade down.

The Blocks are where the game gets interesting. There are 17 variants stamped onto those upper-row tiles, and they activate one of two ways: a winning paying symbol lands directly underneath one, or another active Block fires its effect into it. The simplest is just an empty stone with no payoff. The destroyers blow up an entire row, an entire column, or both diagonals from a corner. Coloured gems (red, blue, green) wipe every fire, water, or plant symbol off the bottom rows, and the next cascade refills with only that single kind of symbol locked in.

Then the premium tier. Multiplier Blocks carry values from 2x up to 500x, all feeding into a Total Multiplier that compounds across the cascade chain. Bonus Blocks hold values 1, 2, or 3, destroy three of them in the same round and Free Spins trigger, with the spin count equal to the sum of the activated Bonus values, so a 1+1+3 hit gives five spins. The Total Multiplier persists between Free Spin rounds instead of resetting, which is the rule that drives the 10,000x cap. Super Free Spins can trigger at random on entry, and during those only Multiplier, Bonus, and Gem Blocks fill the upper grid, no dead Blockers wasting slots.

Two edge-case rules deserve attention. Clear every paying symbol in a single cascade and the next cascade lands as one locked symbol kind. Clear every Block symbol in a single cascade and the rest of the round drops only premium Blocks. Both are rare, both are the kind of thing that turns an average spin into a screenshot.

The Buy Feature from Relax Gaming splits into two doors: 70x for Free Spins (3-10 spins random, 0x starting multiplier) or 250x for Super Free Spins (5 spins, 0x start, every Block premium). Visually the reels sit inside a sunken Atlantean temple with palm-tree cliffs in the background, the logo painted in the same primary-colour Bejeweled palette as the gem Blocks. Mystical archaeology dressed up as a match-puzzle.
