Hammerstorm Slot Game Details

Symbols and Payouts

All symbols pay when they land on adjacent reels from left to right, starting with the first reel.

• High-value symbols include Viking gear such as a shield, battle-axe, helmet, gauntlets, and a drinking horn.
• Low-value symbols are the stylised A, K, Q, and J royals.
• The wild symbol is Thor’s hammer (Mjölnir), which substitutes for all symbols except the Thor symbol, Lightning symbols, and Coin symbols. It can land on any reel.
• Gold and silver coins, along with different Lightning symbols, act as money symbols and can have random values from 0.5x up to 10,000x your total bet.

Respins Feature

The respins feature is the main mechanic in Hammerstorm and can be triggered in two ways:

1. Randomly: By collecting red, green, or purple Lightning symbols in the chests above the reels during the base game.
2. Thor Trigger: Landing the Thor symbol on reel one along with at least one Lightning symbol anywhere else on the grid.

When the round starts, you get five respins on a 5×5 grid. A 2×2 collection zone appears and moves to a new random spot after each respin. Any Coin or Lightning symbols that land inside this zone have their values collected.

Zone Expansion

As you collect Lightning symbols in a special meter during the round, the collection zone gets bigger:

• Collect 5 Lightning symbols: Zone expands to 3×3 (+3 respins).
• Collect 4 more: Zone expands to 4×4 (+2 respins).
• Collect 3 more: Zone expands to 5×5 (+1 respin).

Feature Modifiers

Depending on how you trigger the round, up to three modifiers can be active:

• Double: Gold versions of symbols appear. These gold symbols are collected twice, first for their original value and then again for a new random value.
• Expand: The grid can grow to 7×6 or 7×7, and the collection zone can also expand up to 7×6.
• Spins: Some symbols can have a “+1 Spin” value, giving you an extra respin when collected.

Ante Bet Options

You can choose to increase your bet multiplier to change how the game plays:

• Normal Play: Uses a 20x bet multiplier.
• Ante Bet 1 (500x multiplier): Guarantees one Thor symbol on reel 1 with every spin.
• Ante Bet 2 (1000x multiplier): Guarantees at least 5 Lightning symbols on every spin.

Note: The RTP remains 96.50% regardless of the Ante Bet setting.

Overall Impression

Hammerstorm is a feature-focused slot in which the base game primarily sets up the respins mechanic. If you like structured bonus rounds, expanding grids, and collecting values, you’ll probably enjoy it. Players who prefer frequent small wins might find it slow.
