About Neptune

Neptune by Portomaso Gaming is a slot playable with cryptocurrency on Stake. Remember that RTP is a statistical average over thousands of spins, not a guarantee for any single session.

The maximum potential is 400,000× your stake. This is the payout ceiling, reached very rarely and usually only via the top bonus feature; treat it as a limit, not an expectation.

The slot's key mechanics include bonus game, bonus symbols, jackpot, wilds, scatter. Most of the potential is delivered through these in the bonus rounds.

Before playing for real money, try Neptune in demo mode to learn the bonus frequency and behaviour risk-free — the demo math is identical to real play. Gamble responsibly, within a pre-set budget. 18+.
