ProEverything on this step comes with Pro. Try it on the preview: you decide at Publish.

ScheduleProWhen the link opens, closes, and the day it is for

🗓 Open only between two dates?The link stays the same. Outside the window players get a page saying it is not open yet, or that it has closed.

When is your event? (optional)?Optional, with Pro. We use it to send you a reminder the day before and a report of how it went the morning after.

TimerProHow long players get

⏱ Timed challenge?A clock the server keeps, one play per device. On a multi-step lock each step gets its own time, and the whole game gets their sum. Answers that come too fast are refused and suspicious plays are flagged for you.

Access and participantsProWho can play, and what you keep from them

Maximum number of playersMaximum number of attempts?The lock stops accepting answers once this many have been tried, across every player.Access code?Players must type this before the challenge starts.

🥇 Only the first player to solve it wins?The first correct answer takes the reward and closes the lock. Everyone who opens the link after that reads that it has already been played, and cannot answer.

🎁 Limit how many people win?Everybody can still play. Only the reward runs out: once the last one is taken, later players get a sold-out screen instead of the pad.

✉ Ask for the player's email?Asked once the lock opens, just before the reveal.

🪪 Ask for the player's first and last name?Asked once the lock opens. For a class: you see who finished, by name.

🏆 Leaderboard?Players sign the board with a nickname when the lock opens, and see everyone who finished before them.

👥 Challenge a friend button?Under the reveal, players are offered the same lock to pass on to somebody else. Off by default: a proposal or a client's document is not meant to travel.

WebhookProCall a URL of yours every time a player opens this lock

🔗 URL to call on each unlock?An HTTPS POST with a JSON body: the lock, when, how many tries, the step of the game, and the player's email when you ask for one. Never the answer, never the reveal. Signed with the secret below, so your side can check it came from us.

What turns sunlight into sugar?

Clue:

🍃 Leaves take in light, water and carbon dioxide, then make sugar 🍬 and release oxygen.

🤔 What is this process called?
✏️ One word, starting with the Greek for light: photo.

Type your answer

Not quite. Think of what a leaf does all day in the sun.

💡 Hint: Photo (light) + synthesis (making by putting together). Glue them into one word.
