How Are Typeform Giveaway Winners Chosen?

At random, unless you pick them yourself. A Typeform giveaway is a normal Gleam Competition, so you choose winners on the Winners tab once it ends.

• Random draw. Gleam picks from valid entries. Each entry is a chance to win, so someone with more entries has better odds. See drawing random winners.
• Referrals. These don't pick winners on their own. Add Viral Share and entrants earn entries when friends enter through their link, which raises their odds in the draw.
• Judging. To reward the best answers, read the responses in Typeform and choose winners with Manual Winners (Pro Plan and above).

Before you draw, check the Actions tab and invalidate entries that break your rules. Then contact your winners yourself, because Gleam doesn't do that for you.
