Reveal Card
Players tap a card and it turns over to show a prize or a friendly miss, with the odds or the timing you set.
A Reveal Card is a card that turns over when players tap it, showing whether they've won. Studio lists it as Reveal Game. Here, Lindenhall's Bloom Reveal gives a spring bouquet to one player in four.
