I actually think that video poker is way too slow for my liking and I'd rather get some variance and major wins with slots. And most people tend to agree with this I feel.
Regarding the game phase, yes it's more quick to slots. Even slots are considered as luck-based games, we can win most playing at these compare spending hours in video poker or any related games. Luck is just around the corner. We might attract it during early spins or for much longer spins.
Comparing both slots and video poker, it's really much excited to see those spinning wheels especially when a decent multiplier win will flash on the screen.
