01 — For Whom
Who this is for
01
Want to draw visitors with a mystery game
People will travel from far away if there's a mystery game to play. Great for new visitors at roadside stations, shopping streets, or theme parks.
02
Want to turn dwell time into sales
Longer stays naturally increase visits to fresh-produce stands, gift shops, soft-serve counters, and restaurants.
03
Want to extend dwell time
Mystery game participants stay for several hours — exploring the shopping floors and using restaurants during breaks.

FAQ
6 ITEMS
Q.01 Do participants need to install an app? −
No. Answers can be submitted from a smartphone browser. Just scan a QR code on a flyer or follow a URL provided by the organizer.
Q.02 How should we design on-site hints? +
Use real-world scenery or objects as clues, or post printed hints around the location. Avoid giving the answer directly — provide 'a clue to solve the puzzle' instead.
Q.03 Can rewards be tiered by the number of correct answers? +
Yes. Users can check the items they've earned from T&T's 'Bag' screen. Using the reward item, you can set thresholds (e.g.
X points or more, Y items or more) to grade rewards after the mystery game ends.
Q.04 Can people who can't visit in person also participate online? +
Yes. If you place all hints online, the entire event can run remotely. T&T itself works fully online.
Q.05 Can cheating (e.g. asking friends for answers) be prevented? +
Online controls can limit answer count and timing, but offline collusion can't be prevented entirely. Ask participants to play in good faith as part of the event etiquette.
Q.06 How many participants can it support? +
There are no fixed caps on items or events. For simple mystery games, the free Basic plan is enough. If you also distribute and operate NFTs, the first 30 are free; 31 or more require a paid plan.
