Each spin lands symbols on a 5x3 grid, set in a Norse world of hammers, shields and horns. Wins pay on 40 fixed paylines, read from left to right, and a line needs at least 3 matching symbols to pay. The WILD is the Mjolnir hammer. The other symbols are the round shield, double axe, horned helmet, gauntlets, drinking horn and the cards A, K, Q and J.
LIGHTNING money symbols, or THOR on reel 1, can trigger RESPINS. It starts with 5 respins on a 5x5 grid, and the marked zone grows as you collect LIGHTNING symbols. The banner says FREE RESPINS, but this is not classic free spins. DOUBLE can bring gold symbols, EXPAND makes the grid 7x6, and SPINS adds extra respins. SUPER BONUS needs all three modifiers active.
Hammerstorm respins
This settles how each bonus starts and what it changes on the reels.
RED, GREEN or PURPLE LIGHTNING money symbols, or THOR on reel 1, can trigger the RESPINS Feature on 5x3 reels. 5 respins start on a separate 5x5 grid. Collect 5, 4 or 3 LIGHTNING MONEY symbols, growing the zone from 2x2 to 3x3, 4x4 or 5x5, awarding extra respins.
Base game reelsExtra respins
This modifier switches on at random during a RESPINS round. GOLD versions of COIN and LIGHTNING money symbols can then appear. Collecting a GOLD symbol pays its shown value, then a new random value. That is a double collection.
RESPINS roundDouble collections
When this modifier activates at random, the RESPINS grid becomes 7x6 instead of 5x5. The marked zone can then grow up to 6x5, 6x6 or 7x6.
Round startBigger grid
Randomly activated during a RESPINS round, this modifier lets a +1 SPIN value appear on COIN and LIGHTNING money symbols. Collecting one awards 1 extra respin.
Mid-round+1 SPIN values
On the reels, RTP means the share of staked money paid back over time, based on A$100 staked. It says nothing about one session. The version this site runs is shown in the game rules.

Five steps, one spin
Beepbeep Casino lays out each round in plain steps, so you know the rules before you spin.
Reels stay still until you pick a stake from A$0.20 up to A$120. Every prize scales with that stake, so A$0.20 and A$10 are the examples here.
Symbols land on the 5x3 grid and pay left to right across 40 fixed paylines. Three matching symbols on a line is the fewest that pays.
On the reels, RED, GREEN or PURPLE LIGHTNING symbols and THOR on reel 1 can trigger RESPINS. The base game also lists WILD Mjolnir hammer, Gold Symbols, Growing Reels and Multiplier.
Once triggered, the reels switch to a separate 5x5 grid with 5 respins. Collecting LIGHTNING money symbols grows the marked zone from 2x2 and adds respins.
Every spin on the reels costs the stake you chose, so set your limit before the first spin. The National Gambling Helpline is 1800 858 858.

Lightning symbols and THOR on reel 1 are what open the RESPINS, and when they land is left to chance. How often that happens cannot be known in advance, for any session. Two sessions with the same bet can end in very different places. The RTP describes the long run only, so one session can finish well above or well below it.
Each spin on the 5x3 reels is paid under one RTP version, and that version is shown only in the game rules. Check the rules screen before you start, so you know which figure applies to the game you are about to play.
Spins on the reels move through the paytable, but the maximum win is a ceiling reached very rarely. Hitting it depends on the same random outcomes as every other spin, so no bet size or waiting time brings it closer. The top payout is set by the game and shown in the table on this page.
Demo or cash

Choose when you will stop before the first spin, and keep to it after a win as well as after a loss.
Set deposit and loss limits in your account before you open Hammerstorm. Lower them when your budget changes, not in the middle of a losing run.
If Hammerstorm stops being fun, take a break and do not return on impulse. Asking for help is a sound step, not a failure.
Five things to know
The return, demo access, top win, volatility and bet limits, in plain terms before you spin.
Each spin on the 5x3 reels returns 96.50 percent of the stake over a very large number of spins. Hammerstorm has one RTP version, so there is no other setting to pick. A single session can end well above or below that average.
The reels here run real-money spins, so start at the A$0.20 minimum to learn the 40 fixed paylines. Watch how the RESPINS round starts before you raise the stake.
Spins on the 5x3 reels can reach 10,000 times the bet, the game's top win. At the A$120 top bet that is A$1,200,000, and at the A$10 example bet it is A$100,000. Nobody can know in advance when a spin will reach it.
Wins on the 5x3 reels can be far apart and vary a lot in size, because Hammerstorm has high volatility. Long stretches without a win are part of that profile. No one can know how often the RESPINS round will come or what a session will return.
Bets on the 5x3 reels run from A$0.20 up to A$120, the highest bet allowed here. The paytable uses A$0.20, and a win needs at least three matching symbols from the left. The A$10 figure is only an example, not a limit.
