There are a couple different Puzzle Boosters that can be earned from the Monthly Calendar, the Bingo Builders event, and from limited-time offers.
Examples:
- +1 Extra Puzzle Tile in Bingo rounds.
- 2X (Double) Puzzle Tiles in Bingo rounds.
- Automatically applied -- the multiplied amount is visible from the Card/ Bet select screen next to the bet meter.
In the top Events bar, tap on the Puzzle Booster icon to see which one is active.
Note: The bonuses in the Monthly Calendar can change and may not always offer the same item each day of the week.
