Slots with features: choice of bonus, risk game, symbol upgrade

Introduction

Modern online slots strive to stand out not only with graphics and themes, but also with unique mechanics that make the game deeper and more interesting. In 2025, machines with additional features gained particular popularity: the choice of a bonus, a risk game and an upgrade of symbols. These elements allow players to influence the process and result, which increases engagement and excitement.

1. Feature "Bonus Selection"

The essence of mechanics

The player decides which bonus to activate after dropping a certain combination or launching freespins. It can be:
  • Increase free spins
  • Increase the win multiplier
  • choosing between low and high volatility.

Why it works

Gives the player a sense of control;
Allows you to adapt the strategy to your bankroll;
Increases interest in re-runs, as you can try different options.

2025 examples

Pragmatic Play and Play'n GO actively use the option of choosing a bonus in new releases, giving players two or three scenarios for the development of events.

2. Gamble Feature

The essence of mechanics

After winning, the player is invited to take a chance - to double or increase the payment by guessing the card, suit or other parameter.

Risk play options

Doubling by map color;
Multiplication of × 4 in suit;
Wheel of fortune, where different multipliers are possible.

Why it's popular

Creates an instant excitement element;
Allows you to quickly increase your winnings;
Makes even small payments potentially significant.

2025 examples

The classic risk game remains in demand in slots from Amatic and Novomatic, but new studios add more dynamic formats - for example, risk through mini-bonuses or random tests.

3. Feature "Upgrade symbols"

The essence of mechanics

During bonus rounds or cascades, weak symbols become more expensive, which increases the chances of large combinations.

Upgrade Options

Cascade upgrade - each time you win, the symbols increase their rank;
A collection of upgrades - the player collects special icons, and as they accumulate, they improve the basic characters;
Dynamic upgrade - activation of the upgrade depends on random events (Wild, Scatter, multipliers).

Why in demand

Creates a sense of progress in the round;
Pushes for a long game, as the value of spins grows;
Improves the chances of mega-wins on long runs.

2025 examples

Providers Red Tiger and NetEnt are actively implementing symbol upgrades in slots, making bonus games as spectacular and profitable as possible.

4. Combination of features in one slot

The best releases of 2025 combine several features at the same time: for example, choosing a bonus + upgrading symbols or a risk game after freespins. This boosts dynamics and makes each spin unique. Players appreciate this variability as it enhances both excitement and strategic component.

Result

Slots with features "choice of bonus," "risk game" and "symbol upgrade" have become one of the main trends of 2025. They stand out not only for generous payouts, but also for giving players more control, emotions and opportunities to win. It is these mechanics that make modern machines not just a game, but a full-fledged interactive experience.
