1] The highest denomination slot machines generally offer the best payouts.
As the number of players decreases, the total pot value increases, and the casinos are more than happy to offer better odds to the few remaining players. You can find more information about high-limit slots at casinoroom.com and win mega moolah.
2] The odds of hitting linked progressive jackpots like Megabucks and Wheel of Fortune at brick-and-mortar casinos remain the same.
This is the case because all casinos, online and otherwise, want to draw a predictable profit from each game. In the case of progressive jackpots at brick-and-mortar casinos, there are a limited number of machines that can be linked, but this is not true of online slots.
3] Online slots and progressive jackpots generally offer better payouts and odds than brick-and-mortar casinos.
Online slots and progressive jackpots have lower maintenance costs than brick-and-mortar establishments, and this allows them to make bigger payouts. What you get with a real-world casino is the physical experience of sights and sounds, though advances in technology are making online casinos increasingly life-like.
4] Comp-lovers and bonus-lovers love slot machines.
Online casinos offer cash and credits; offline casinos also offer dinner, drinks, and shows. People who want to focus on actually playing slots tend to get more out of the special offers from online establishments.
5] Online and brick-and-mortar slot machines have various advantages and disadvantages.
Online casinos offer large payouts and complete convenience in terms of transferring funds. Brick-and-mortar casinos offer the glitz and thrill of Vegas and Atlantic City, with all of the associated thrills—and drawbacks, such as having to travel and to park.
6] There is very little chance of being cheated by any slot machine.
Since the casino operators can set the return however they like, and since they live and die by their reputations, there is little incentive to rig individual slot machines.
7] Some of the advertising for both online and brick-and-mortar slot games is misleading.
This is actually a minor issue. We all know that advertisers put the best spin on their products, so it is up to players to research casinos rather than relying on their promotional materials.
