How the Base Game Works
this slot plays on a 5×3 grid with 20 paylines in the base game. Premium symbols pay between 20x and 125x your stake for 5-of-a-kind wins, and the wild symbol substitutes for all regular pay symbols to complete combos. The theme is Atlantis – sunken ruins in the base, then a shift to the city in its glory days once you hit the bonus round.
The base is sparse. Most sessions churn through spins waiting for the scatter trigger. Occasional giant symbols can merge across 2-3 reels at random, pushing payouts up to 2,500x your stake on a lucky day – but that is rare. The Super Stake ante bet feature is the real lever here.
Super Stake – Double Stake / Double Free Spins Odds
Toggle Super Stake on before any spin. It doubles your regular stake and, more importantly, doubles your odds of landing the Free Spins bonus. The cost is simple: you pay 2x the base bet. The payoff is a measurable boost to trigger frequency when you are chasing the bonus round.
Most players turn it on and leave it on. Base game action is thin enough that the extra cost feels justified by the bonus acceleration.
Scatter Trigger and Free Spins
The wild symbol also acts as a scatter. Land 3 or more wilds anywhere to trigger the Free Spins bonus. You always win 10 free spins – the count does not change based on how many scatters you land above 3. However, you do win a scatter prize at the same time:
Bonus Round – 5×5 Grid / 40 Paylines / Reel Merges
During Free Spins, the grid expands to 5 rows and 5 reels, giving you 40 win ways instead of 20. This is where the slot grows teeth. At random times during the bonus, a reel syncing feature triggers: 2 to 5 reels can merge to land giant symbols, turning a single spin into a massive payout machine.
A single merged reel can push wins to 5,000x your stake. Full-screen merges and cascading wins can spike that further, capping at the 10,000x max. Most of the time you merge only 2-3 reels, but the potential is there on every spin.
You can retrigger the bonus round to win extra spins if wilds land during Free Spins. Each retrigger adds 10 more spins and another chance at merged reels.
Bonus Buy – Instant Entry at 100x Stake
Non-UK players can purchase the Free Spins bonus directly for 100x your current stake. The purchase guarantees 3+ scatters on the next spin, triggering the bonus immediately.
This is a clean way to skip the base grind and jump straight to the 5×5 grid if the wait feels too long. Cost is fixed and transparent.

RTP and Volatility
this slot runs at 95.8% RTP and carries high volatility. This means long dry spells in the base are normal, and the bonus round is where the variance swings hard. Wins cluster around the Free Spins feature and the reel merge mechanic.
