Bonus Features
Here is a rundown of all of the features the Sugar Rush slot game includes:
Tumble
The Tumble feature means that after every spin, winning combinations are paid, and all winning symbols disappear. The remaining symbols fall to the bottom of the screen, and the vacant spots are filled with fresh symbols cascading from above.
Tumbling will continue until no more winning combos appear as a result of a tumble. All wins are added to your balance after all of the tumbles resulting from a base spin have been played. This feature is commonly found in Cluster Pays and Megaways slots.
Multiplier Spots

Whenever a winning symbol explodes, it marks its spot on the grid, which you can see with the golden sweet wrappers below. After the second time a symbol explodes on the same spot, a multiplier is added to the spot, starting from 2x and doubling every time one more symbol explodes on top of it up to a maximum of x128.
This multiplier is effective for all winning combinations landing on that spot. If more multipliers are involved in the same winning combination, they add to each other. In the base game, all of the marked spots with multipliers last until the end of the tumbling sequence, clearing only when no more tumbles occur.
Free Spins

Landing 3, 4, 5, 6 or 7 Scatters triggers the Free Spins feature and awards 10, 12, 15, 20 or 30 free spins respectively. During the feature which you can see in the screen above, marked spots and their multipliers remain in place until the end of the round and can increase the subsequent tumbles across all of the free spins. Land 3, 4, 5, 6 or 7 Scatters during the bonus round anywhere on the screen to win 10, 12, 15, 20 or 30 extra free spins respectively. Special reels play during this bonus feature.
