Basic game features: re-backs, extensions, mystery symbols - the best implementations

Introduction

In most modern online slots, the player's main interest is focused on bonus rounds. However, more and more providers are introducing features into the base game that make backs without a bonus no less exciting. Re-spins, expanding symbols and mystery symbols can significantly increase the winning potential even before the activation of freespins.

For Australian players, this means that even in a short session, you can experience dynamic and profitable gameplay without having to wait for a rare bonus.

Basic Game Features

1. Re-spins

What is it: repeated rotation of the drums without additional bet or with partial payment, activated by a certain combination of characters.
