Choose an activity for audience input, a shared game, team participation, or reviewing a session's results. Open an activity guide for its format and supported presentation surfaces.

- [Live Polls](https://decka.dev/activities/live-polls.md): Run live polls inside your slides. Your audience votes from their phones and results animate on the big screen in real time. Free to start, no app needed.
- [Word Clouds](https://decka.dev/activities/word-cloud.md): Create a live word cloud from your audience's answers. Words grow as votes repeat — perfect for icebreakers, retros, and classroom check-ins. Free to start.
- [Q&A Sessions](https://decka.dev/activities/q-and-a.md): Let your audience submit and upvote questions from their phones. The best questions rise to the top of the big screen — no more awkward silence or mic runs.
- [Live Reactions](https://decka.dev/activities/live-reactions.md): Let your audience react to every slide with live emoji bursts, quick ratings, and comments — instant energy for all-hands, webinars, and lectures.
- [Reveal](https://decka.dev/activities/reveal-poll.md): Everyone answers privately and nothing appears until you say so. Perfect for most-likely-to rounds, silent retros, and exit tickets where the first answer must not anchor the rest.
- [Live Quizzes](https://decka.dev/activities/live-quiz.md): Turn any presentation into a live quiz with countdowns, scores, and a leaderboard. Great for training recaps, classrooms, and team trivia. Free to start.
- [Questionable!](https://decka.dev/activities/questionable.md): A team trivia board game for any room. Teams pick a category and value, everyone answers on their phone, and the team's answer counts. AI builds the board.
- [Bingo](https://decka.dev/activities/presentation-bingo.md): Play bingo bound to your slides: words mark off as you present, first full row wins. The attention hack for trainings, onboardings, and long meetings.
- [Guess the Doodler](https://decka.dev/activities/guess-the-doodler.md): Everyone doodles on their phone, then the room guesses who drew what. The fastest icebreaker for team meetings, offsites, and workshops.
- [Doodler Decoy](https://decka.dev/activities/doodler-decoy.md): Other teams plant decoys. An artist draws the secret word, then locks the drawing before their team votes for the truth. Built for all-hands and offsites.
- [Charades](https://decka.dev/activities/charades.md): Run charades on the big screen: a word only the performer sees, a clock the whole room watches, and guesses from every phone at once. Word bank included.
- [Meeting Dodgeball](https://decka.dev/activities/meeting-dodgeball.md): Split the room into teams for 2.5D dodgeball played live from phones on the big screen. The energizer that wakes up any meeting or offsite.
- [Mingle Match](https://decka.dev/activities/ice-breaker-activity.md): The ice breaker that actually mixes a room: everyone is paired with someone new each round, shown a shape to hold up, and given a question to talk about.
- [Group Mixer](https://decka.dev/activities/group-mixer.md): Split a room into random groups for lunch or breakouts. Everyone scans one code and gets a table and a shape to find it by. Latecomers are seated for you.
- [Team Naming](https://decka.dev/activities/team-naming.md): Split a room into even teams in seconds, then let each team argue its way to a name on their phones. The two-minute opener that makes every later team game work.
- [Spin the Wheel](https://decka.dev/activities/spin-the-wheel.md): Put a spinning wheel on your slide and let it choose. Use your own list, or let the room fill the wheel from their phones, then spin it together.
- [A/B Tests](https://decka.dev/ab-testing.md): Show variant A to half the room and variant B to the other half, then compare live results. Test messaging, designs, and ideas with a real audience.
- [Tier List](https://decka.dev/activities/tier-list-maker.md): A tier list the whole room fills in at once. Everyone ranks privately, then the board shows where you agree — and, more usefully, exactly what you disagree about.
- [Activity Reports](https://decka.dev/activities/reports.md): Get a report after every interactive session: poll results, quiz scores, questions asked, and who participated — ready to review and share with your team.
- [Insights Hub](https://decka.dev/activities/insights.md): See how your audience engages across every presentation: participation, activity performance, and trends over time — all your session data in one hub.
