How bonus rounds are activated: Scatter, symbols, events

Introduction

Bonus rounds are a major source of big wins in modern online slots, and knowing how they are triggered helps the player build strategy. Different games have their own activation conditions: from the appearance of certain characters to random triggers that can work at any time.

1. Activation via Scatter characters

Definition: Scatter is a special character that activates a bonus, even if not on pay lines.
Standard condition: most often you need to catch from 3 to 5 Scatter characters in one rotation.
Bonus example: series of freespins, bonus game, multipliers.
Features: in some slots Scatter can only fall on certain drums (for example, 1-3-5).

2. Bonus Symbols

Unlike Scatter, bonus symbols usually activate unique minigames or features, often with story content.
Frequent activation conditions: 3 + bonus symbols on active lines or in any position.
Examples of features include Pick-and-Click, Wheel of Fortune, Progressive Levels.

3. Random events

Some slots have random triggers that trigger the bonus at any time without dropping specific characters.
Examples:

• Instant launch of freespins.
• Add more Scatters to the reels.
• Launch a unique animation leading to a bonus game.

4. Combined conditions

Some mechanics require a combination of several factors:

• 2 Scatter drop-out + third character finish on repeated rotation.
• Wild + Scatter combination for enhanced version of bonus.
• Filling the scale or collecting a certain number of characters for several spins.

5. Progressive activation

In a number of slots, the bonus opens gradually:

• Collect symbols (for example, 100 coins or tokens).
• Fill energy or progress indicator.
• Reaching a certain level in a multi-level bonus game.

6. Bonus Buy

In modern slots, it is possible to activate the bonus round immediately by paying a fixed amount.
Pros: Instant access to freespins or minigame.
Cons: High cost and risk of getting a small win.

Conclusion:

• Activation of bonus rounds can occur through Scatter or bonus symbols, random events, cumulative mechanics, or feature purchases. Understanding all possible ways helps the player choose slots that better suit their playing style and expectations for bonus frequency.
