Online casinos offer a wide range of bet types to suit a variety of player preferences and budgets. Some of the most common bet types available at online casinos include:

• Straight bets: These are the most basic type of bet, where players wager on a single outcome or event. For example, betting on a specific number to come up on a roulette wheel or on a particular hand to win in blackjack.
• Multi-line bets: These are bets that cover multiple outcomes or events, such as betting on multiple numbers in roulette or on multiple hands in blackjack.
• Parlay bets: These are bets that combine multiple straight bets into a single wager, with the potential for higher payouts. For example, betting on the outcome of multiple football matches as part of a single parlay bet.
• Progressive bets: These are bets that involve a gradually increasing stake, based on the outcome of previous rounds. For example, in some variations of roulette, players may increase their bet after each win in an effort to capitalize on a winning streak.
• Side bets: These are bets that are placed alongside the main bet in a game, such as the "insurance" bet in blackjack or the "pair plus" bet in three card poker.

Overall, the range of bet types available at online casinos allows players to customize their betting strategy and tailor their wagers to their individual preferences and risk tolerance.
