What makes a slot 3D
Animated symbols, cut scenes and bonus rounds that play like a short game. Studios such as Betsoft built their name on this style; most big studios now use 3D effects somewhere.
Do they pay differently?
No. Graphics do not change the odds. Compare the RTP in the information screen and the volatility, which tells you how often and how big the wins are.
