Bonus features are special modes in slot machines that are triggered by landing certain combinations of symbols. They are designed to increase the entertainment value of the game and create the chance for a big win.

Here's how bossmahjong login and the main types of bonus features work:

1. Free Spins
This is the most common bonus, featuring a series of free spins on the reels.

Activation: Typically requires landing a certain number of Scatter symbols (often 3 or more) anywhere on the reels.
Mechanics:
The player receives a fixed number of free spins (e.g., 10, 15, or 20).
During free spins, the player's bet is not deducted from the balance.
All winnings received during free spins are credited to the account.
Upgrades (Modifiers):
Expanding Wilds: The Wild symbol can expand to cover the entire reel.
Multipliers: Each win is multiplied by x2, x3, etc. Retriggers: If Scatter symbols appear again during free spins, the number of free spins is increased.
Locked Symbols: Some symbols may "stick" to the reels until the end of the round.
2. Respins
Unlike free spins, respins involve the reels spinning only partially, rather than fully.

Mechanics:
The player presses the spin button.
The reels stop spinning, but some of them (usually those with winning symbols or Wilds) remain locked in place.
Only the remaining reels spin to try to form a winning combination.
The player can receive multiple attempts (re-spins) if new high-value symbols appear on the screen.
Feature: Often used in slots with the Cascading Reels or Tumbling Reels mechanic, where winning symbols disappear and new ones fall from above. 3. Bonus Mini-Games (Pick-and-Click / Bonus Wheel)
These are separate game screens that open over the main slot interface.

Activation: Landing special symbols (often Scatter or Bonus).
Mechanics:
Item Selection: The player must choose one of several objects (chests, doors, cards), each of which contains a prize.
Wheel of Fortune: The player spins a wheel that is divided into sectors with different multipliers or prizes.
Goal: Get a guaranteed win or a set of prizes, which are then combined in the main game.
4. Cascading Reels (Tumbling/Cascading Reels)
While this is often part of the main game, it can also be a standalone feature.

Mechanics:
After a winning combination, symbols explode or disappear.
New symbols fall from above to take their place.
If the new symbols also form a win, the process repeats (cascade). Each subsequent win in a cascade is often multiplied by an increasing multiplier.
Important rules of bonus features:
Randomness: The triggering of any bonus feature is completely random and depends on the RNG. It is impossible to predict when it will activate.
Beat independence: The bet size does not affect the probability of triggering the bonus (unless the slot has specific rules requiring the maximum bet to access the jackpot).
Transparency: All bonus feature rules (number of spins, re-trigger conditions, multipliers) are clearly stated in the "Game Rules" or "Information" sections.
Why are bonus features important?
For the player: The opportunity to win a large sum without the risk of losing additional funds (in the case of free spins) and to experience a more dynamic gameplay.
For the casino: Increased player engagement and time spent playing.
Remember that bonus features do not change the house edge (RTP). They only change the volatility and nature of payouts, making the game more varied.
