While playing Bingo Infinity, you'll notice that your cards will contain some squares with golden cubes with question marks on them - these are random Stage Mastery pieces. Daubing these golden cubes will allow you to earn a random Stage Mastery piece, which will contribute to your overall Stage Mastery progress.
On the screen where you're able to adjust the number of Cards played and Coins bet per card, you'll see just above the green PLAY button is a Bonus Items count; these Bonus Items are the number of Stage Mastery tiles spawning on your cards.
If you're betting the absolute fewest number of Coins per Card, no Stage Mastery items will spawn on your cards, and the Bonus Items area will reflect 0. Increase your bet per card to increase the number of Stage Mastery tiles spawning on your cards.
Completing Stage Mastery will permanently increase your total Daily Bonus Coins!
