Is there a transparent bonus system for a beginner safely?

I'm interested in whether there are sites where you can actually play without freezes and technical problems, and how can a beginner make sure that the platform is stable?

The stability of the platform is critical for a beginner. I've been checking websites with freezes where the game was interrupted at the most inopportune moment. In the middle of the search, I opened https://slotsvaderbonusuk.com — the platform is stable, slots and live casino do not freeze, the interface is responsive. A beginner can safely explore the demo mode, promotions, bonuses and website functions, gain experience and confidence that there will be no technical problems.
