On the 6x5 grid, a win needs at least eight matching symbols anywhere on screen, since there are no paylines or ways. Gemhalla blends Gems, Mythology and Norse imagery into one game. Winning clusters pay, then the Tumble feature drops new symbols in until no more wins form. The base game uses this cascade on every spin.
Four or more Viking longship Scatters anywhere on the grid start a Free Spins round with 15 spins. Three or more Scatters landing during that round add five more spins, a Retrigger. Multiplier symbols add up across the whole round, and each later winning spin takes the total. Scatter Pays means the longships count toward wins as well.

After this, you know how each bonus starts and what it changes.
Four or more Scatter longships anywhere on the grid start Free Spins with 15 spins. Each spin that lands three or more Scatters during the round adds 5 more spins. Multiplier values build across the whole round and apply to every later winning spin.
Base game spinsFree Spins, multipliers
Purchase the Free Spins round directly for 100x the total bet. The next spin after the purchase triggers Free Spins. Buy Bonus and Chance x2 are mutually exclusive, so Chance x2 is disabled while Buy Bonus is active.
Base gameFree Spins round
On the reels, the Scatter has double the chance to land once Chance x2 is switched on. The toggle adds a 25% surcharge on the total bet. The RTP stays at 97.17%, the same as the base game, so only the trigger odds change, not the game content.
Base game spinsDouble Scatter chance
The base game runs on a 6x5 grid with no paylines or ways. A symbol pays when 8 matching symbols appear anywhere on screen. Winning combinations pay, then new symbols drop in, and this repeats until no more wins form.

Spins on the 6x5 grid return a share of each stake. On an A$100 staked basis, 97.17 means A$97.17 back on average over time. The version run here is shown in the game rules.

Before the first reel
Settles the order of a round, from choosing the bet to the limit that ends the session.
Every spin on the 6x5 grid starts with the bet you set, from A$0.20 up to A$50. The bet sets the money behind each win.
Wins form from clusters of matching symbols anywhere on the grid, with no paylines. Eight matching symbols is the fewest that pay, and winning groups pay before new symbols drop in.
Winning symbols clear and the Tumble cascade drops new ones in, so one spin can chain wins. Scatter symbols count anywhere on the grid and can pay in the base game.
Four or more Scatter symbols anywhere on the grid start Free Spins with 15 spins. In the round, three Scatters in a single spin add 5 more spins.
The reels stop after each spin, and the limit you set before the first spin decides when play ends. No spin can be predicted from the one before it.

Learn Before Betting
You will have tried Gemhalla in demo mode and know what the real version needs.
The reels spin in the demo without any money, and they pay nothing. The real game needs an account at Unibet Casino and you must be 18+.
PlayScatter symbols land on the 6x5 grid at random, and each spin decides whether the free spins round starts. Nobody can tell in advance how often that round arrives. Each session is random too: the result depends on luck, and the RTP describes only the long run. Each spin draws a new outcome, so past spins do not predict the next one.
Every spin on the 6x5 grid follows one RTP version. The game rules name that version, and the lobby tile does not show it. Open the rules before your first bet, since the figure there sets the long-run return.
Winning combinations on the reels can reach x5,000 the bet, and that is the ceiling for Gemhalla. Hitting it is very rare, and nobody can say when or if a round will get there. Treat the maximum win as the top of the scale, not a target for any session.

Gemhalla questions
Read this before your first spin, when the rules and triggers still matter most.
Before the first spin, read the rules that decide every outcome: the 6x5 grid, the Base Game and the Free Spins. The paytable lists payouts at the A$0.20 minimum bet, so you can see what each symbol pays before you stake more.
Gemhalla has high volatility. Wins come less often than in low-volatility slots, but single wins can grow large, with a top prize of x5,000 the bet. Play with a budget that can absorb a long run without a win.
Four or more Scatter symbols, the Viking longship, anywhere on the grid start the Free Spins round with 15 spins. Three or more Scatters in one spin during the round add five more spins. Multiplier values accumulate across the whole round and apply to each later winning spin.
Gemhalla has one RTP version, 97.17%. That is the share of total bets the game returns to players over a very long run, so a single session can end well above or below it.
Gemhalla is for players aged 18+. If play stops feeling fun, call the National Gambling Helpline on 1800 858 858 or sign up to BetStop, the national self-exclusion register.
Set a budget before you open Gemhalla and keep to it. Decide how much you can afford to lose, not how much you hope to win.
Decide when you stop before the first spin, and keep that rule after a win. A win is no reason to keep playing past your stop point.
Use the deposit and loss limits in your account before you start. They cap what you put in and what you can lose over a set period.
Take a break whenever the game stops being fun, and self-exclude through BetStop if you need more time away. Stopping is always an option.
