Forge of Olympus Slot by Pragmatic Play

Scatter pays with tumble on a 6x5 grid, and every tumble sequence can pick up multiplier hammer symbols worth 2x to 100x. Those values get summed at the end of the sequence and applied to the total win - so a chain of three tumbles with a 20x and a 50x hammer pays 70x the base amount. The hammers appear in both base game and free spins, and they show up during tumbles too, not just the initial spin.

Free spins run a progressive level system that ratchets up the minimum hammer value. It starts at level 1 where hammers range from 2x to 100x. After collecting 6 hammer symbols, level 2 kicks in and the floor jumps to 8x. Five more hammers reach level 3 at 15x minimum. Four more hit level 4, where every hammer lands between 50x and 100x. The round stays at level 4 from that point, and retriggers are possible with 3+ scatters adding 5 spins.

Four buy options let you skip straight to any level: 100x bet for level 1, 200x for level 2, 400x for level 3, and 500x for level 4. The ante bet alternative costs 25% extra per spin but doubles the scatter frequency on the reels. Picking ante disables the buy feature and caps max win at 4,000x instead of 5,000x.

The shield is the premium symbol at 50x bet for 12 or more anywhere on the grid. Helmets pay 25x and chalices 15x at the same count, with six gem types filling the lower tiers.
