On the 6x5 grid, a win forms when 8 matching symbols land anywhere on screen. Gemhalla pays by total symbol count, so no paylines or ways are needed. The theme combines gems, mythology and Norse imagery. Each round uses Refilling: every winning combination pays, then new symbols drop in until no more wins form.
Four or more Scatter symbols, the Viking longship, anywhere on the grid start Free Spins with 15 spins. Three or more Scatters in a single spin during the round add 5 more spins. Multiplier symbols accumulate across the whole round and apply to each winning spin that follows. Retrigger means the round keeps extending while Scatters keep landing.
Looking before you spin
The usual worry is not knowing what the bonus looks like before you spin.
Wins land on the reels, and return to player is the share of stakes paid back across many spins, measured here per A$100 staked. The version Casinox runs is stated in the game rules.

Know each spin
You will have followed one round from the bet to the session limit.
The bet you set, from A$0.20 up to A$50, decides what each spin costs and what every win pays. The paytable is shown for an A$1 bet.
Symbols land on a 6x5 grid, no paylines. Eight or more matching symbols anywhere on screen form a win, then the winning symbols drop out and new ones refill the grid.
Scatter Pays counts Viking longship symbols anywhere on the grid, and Tumble refills after every win. Multiplier symbols build their value across the Free Spins round.
Four or more Viking longship Scatters anywhere on the grid trigger Free Spins, starting with 15 spins. Three or more Scatters in one spin during the round add five more spins.
Decide a loss limit before the first spin, because high volatility means long dry stretches and occasional large wins. Stop when the limit is reached, not after the next win.
Once the reels trigger
This block settles when each mode starts, what happens inside it, and what it costs.
Four or more Scatter (Viking longship) symbols anywhere on the grid trigger Free Spins. You get 15 initial spins. Three or more Scatters in a single spin during the round award +5 more spins. Multiplier values accumulate across the round and apply to each later winning spin.
Base Game spin15 free spins
The next spin after the purchase triggers Free Spins. The Free Spins round is bought directly for 100x the total bet. Buy Bonus stays off while Chance x2 is active, and Chance x2 stays off while Buy Bonus is active.
Base Game betFree Spins round
Scatter symbols on the reels get double the chance to land when Chance x2 is switched on. Switching it on adds a +25% surcharge on the total bet. The toggle only changes trigger odds, not the game content, and the RTP stays at 97.17%.
Bet panelHigher trigger odds
Symbols land on the 6x5 grid and pay by their total count anywhere on screen, with no paylines or ways. Eight is the fewest number of symbols that pays. Refilling cascades: all winning combinations pay, then new symbols drop in until no more wins form.

Gemhalla trial run
Worth opening before your first real-money session, when you want to see how rounds run.
The demo needs no money and pays nothing; the real game needs an account at Casinox and the legal age, 18+.
PlayEach spin on the 6x5 grid of Gemhalla either brings four or more Scatter symbols or it does not, and the screen gives no warning before the Free Spins start. How often that happens cannot be known in advance. The result of one session is random too, whatever the RTP. Two players with the same bet and the same number of spins can end with very different balances.
When a cluster of matching symbols lands on the reels, its payout follows the RTP version that Casinox runs for Gemhalla. That version is shown only in the game rules. Read those rules before you set a bet.
When Refilling cascades keep producing wins, the round total grows step by step, but the maximum win of Gemhalla is 5,000 times the bet. That ceiling is reached very rarely. Nobody can know in advance whether a given session will come near it.
