Examples of Games with Respins:

Wild Symbols

Wild symbols are like jokers in a deck of cards. They can substitute for other symbols in a winning combination, increasing your odds of hitting a winning spin. Some slots even feature expanding or sticky wilds, which can lead to big wins.

Treasure Chests in slots act as containers for hidden prizes. When players land a treasure chest symbol or reach a certain in-game milestone, they get to open the chest to reveal prizes, multipliers, free spins, or other valuable rewards.

Increase Your Prize Feature

Some slots offer an increase in your prize feature that lets you risk your winnings for a chance to double or quadruple them. It’s a high-risk, high-reward option that can make your wins even more thrilling.

Some slots have bonus features with jackpots that offer the chance to win substantial prizes that can be truly life-changing. There are two primary types of jackpots: progressive and fixed. 

Progressive jackpots grow over time as a portion of each spin is added to the jackpot pool, often reaching staggering sums before being won. In contrast, fixed jackpots offer predetermined, unchanging prizes that are typically smaller but more readily attainable.
