Bonus buy slots
Bonus buy slots add a menu option that lets you pay a multiple of your stake — commonly 60x to 150x — to skip straight into the bonus round instead of waiting for it to trigger through normal spins. In real-money play that's a deliberate volatility choice: you're trading a guaranteed cost now for immediate access to the feature that usually carries most of a slot's payout potential. In demo mode here, the mechanic is free to try either way, which makes it a genuinely useful way to see exactly what a bonus round looks like and pays out without grinding base-game spins to reach it. Not every jurisdiction allows bonus buy, and a growing number of studios ship a version of a game with the buy option stripped out for markets where it's restricted — where that applies, our fact table notes it rather than pretending the feature exists everywhere. Below are every published bonus-buy demo we track, filterable by provider, theme and RTP. If you're evaluating whether a bonus round is worth its buy price, the free demo is the only way to check the maths for yourself without spending anything.
