Yes. The demo on this page loads from Pragmatic Play servers and requires no registration, no deposit, and no download. It runs the same RTP and math model as real money play.
Pragmatic Play offers multiple RTP versions. The lowest is 95.45%, and casinos can choose to run it. Check the in-game info panel (page 4-5 of the rules) to see which version you're playing.
Community data shows average bonus returns between 40× and 80×. That means most individual purchases lose money. The rare large win compensates over thousands of attempts, but for a single session, it's a negative-EV bet.
On average, once every 43 spins without Ante Bet (2.3% per spin). With Ante Bet active, the frequency roughly doubles to about once every 21 spins, though you pay 25% more per spin.
The win cap is 21,100× your stake (some sources cite 21,175×). At minimum bet of €0.20, that's €4,220. At maximum bet with Ante Bet (€125), the theoretical ceiling is €2,637,500.
