Is the free demo mode honest?

[molodoy]

Is it possible to play for free to test? Many sites have a demo mode. Is playing for virtual chips any different from playing for real money? Sometimes it seems that in the free mode you get lucky much more often to lure the player. Can I trust the results in the demo version, or is it just an advertisement? I want to test the site first without attachments to see how the games work. Does a reliable casino provide an opportunity to honestly test the software without registration and deposit?
