One type of game to avoid as a newcomer is the high-risk slot machines. These games often pay out infrequently and tend to result in frequent but small wins rather than occasional big wins. Although the lure of winning a large jackpot can be tempting, these games are often less paying in the long run and can yield substantial losses. Look for slots with a moderate volatility to increase your chances of winning smaller but more predictable winnings.

Another option to steer clear of is high-risk European Roulette. The game is associated with a 5.26% disadvantage for players. This makes it less appealing compared to the more player-friendly option, which has a 2.70% edge.

Avoid playing the craps variant at the casino, especially if you're a beginner. The Sic Bo disadvantage for mega888 Sic Bo players is around 2.78%. This makes it less favorable compared to other options like craps.

Blackjack with a low number of decks dealt from a shoe is also not advisable for new players. Some versions of this game allow the dealer to hit a 'soft 17'. This can give them an unfair advantage. To minimize losses, opt for versions of the game where the dealer must stand on a 'soft 17' (also known as 'late surrender option'). However, even the optimal rules may not ensure a win. So always be sure to study and grasp the specific game rules before starting.

Finally, it's crucial for new players to steer clear of expensive games or those that are inherently disadvantageous. The tendency to chase large payouts can cloud a player's judgment but expensive games can be intimidating, especially for those on a limited financial means. It's best to begin with beginner-friendly options and gradually move to higher-stakes options when your financial situation improves.

By being aware of these and other game dynamics, you can avoid costly mistakes and make educated choices when selecting the optimal option for your online casino experience.
