Diving Gloves are boosters that are available when you're already playing a level. Their icon is located on the level-goal sidebar next to the Hammer booster.

Diving Gloves let you swap any two adjacent pieces on the field without using a move.

Here's how you use this booster:
1. Tap the Diving Glove icon.
2. Tap one of the pieces you want to swap.
3. Tap the second piece.
Watch the pieces change places.

You can buy the Diving Glove booster while playing a level or receive it as a daily bonus.
