Our editors can adjust a score after playing the game. Missing data counts as neutral. The score reflects the game's numbers and features, not your chances of winning; slots are games of chance, so please play responsibly.

Hammer of Thunder Overview

Hammer of Thunder is a Norse-mythology slot from Spadegaming, released on 15 May 2023. Thor stands beside a 6x6 grid set in a golden Asgard frame, and wins are paid for groups of matching symbols anywhere on the grid rather than on lines. SlotCatalog lists an RTP of 96.89%, medium volatility, a 285x maximum win, avalanche (cascading) wins and a bet range of 0.20 to 500.

How Wins Are Paid

The paytable pays for 8 or more identical symbols anywhere on the grid, in four bands: 8–9, 10–11, 12–15 and 16 or more. After each win the paying symbols are removed and new ones fall into place, so one spin can pay several times in a row.

The Paytable

Our paytable screenshot was taken at a bet of 100. Converted to multiples of the bet (8–9 / 10–11 / 12–15 / 16+):

  • Odin – 10x / 25x / 50x / 100x
  • Freya – 5x / 10x / 20x / 50x
  • Loki – 3x / 6x / 15x / 30x
  • Crossed axes – 2.5x / 5x / 10x / 20x
  • Horn – 2x / 4x / 8x / 15x
  • Helmet – 1.5x / 3x / 6x / 12.5x
  • A, K, Q, J, 10 – from 0.2x (8–9 tens) up to 5x (16+ aces)

A single cluster of 16 or more Odin symbols therefore pays 100x, more than a third of the listed 285x ceiling.

Theme and Symbols

The grid sits between Thor on the left and the golden halls of Asgard on the right. The premium symbols are portraits of Odin, Freya and Loki, followed by Viking items – crossed axes, a drinking horn and a winged helmet – and five stone-carved card royals from A down to 10.

Thor’s Hammer, Wild and Scatter

Three special symbols appear in our screenshots. A glowing hammer tile lands on the grid, and the panel under the logo labels it with the word TRIGGERS. In one spin the grid turns dark blue and several symbols are replaced by WILD tiles; in another a golden Thor WILD lands next to three SCATTER symbols. The game’s published description says the hammer can trigger respins and that four or more scatters award free spins with a random multiplier.

Our Wins

All three game screenshots were taken at a total bet of 100.00. One cascade sequence, with a large group of crossed axes on the grid, paid 270.00 (2.7x), and the spin with the blue wild effect paid 550.00 (5.5x). The balance shown in the three shots was 1,270.00, 880.00 and 2,000.00, so they come from separate moments of play rather than one continuous run.

The paytable shows why group size matters so much: moving from the 8–9 band to 16 or more multiplies the payout ten times for Odin, Freya and Loki and about six to eight times for the other symbols. On a 36-position grid, groups of 16 of one symbol are rare, so most returns come from the 8–11 bands and from chains of cascades.

Who It Is For

Hammer of Thunder suits players who like cluster pays and cascades with a Norse theme. The medium volatility and the wide 0.20–500 stake range make it usable for both small and large bets.
