FAQ

Common questions

Can children without a phone join?

Children of elementary school age or younger can join with a parent or guardian, playing on the guardian's phone.
If the guardian also plays on a separate phone, they need their own ticket. Each player (one phone) needs one ticket.

Can I buy a ticket on the day?

Yes, until just before your time, unless tickets are sold out. Please buy one on the ticket site.

Can I take photos or videos in the store and post them on social media?

You can post close-ups of chameleons that do not give away where they are. You can also post the short video you can download from the final results screen.
Please do not post anything that shows where the chameleons hide. It spoils the fun for people who have not played yet. Also take care not to film other people.

Is there a reception desk?

No. At the panel by the 4th-floor elevators, open the game link (play code) in your ticket email. After the how-to video and the tutorial, the game starts.

I am running late.

No need to contact us. You can still play if you arrive by the last entry time of the day (usually 19:00, 17:00 on December 31). We do manage time slots, so please try not to be very late. Starting late does not shorten your play time.

Can I leave and come back during the game?

Yes. The 30-minute timer keeps running from the start of the game, though.

I closed the app by mistake.

Open the ticket link again to pick up where you left off. The timer keeps running, though.

Can I keep playing after 30 minutes?

The game ends automatically at 30 minutes. You can still see your results afterwards.

I want to know where the ones I missed were hiding.

The results screen shows where the chameleons you missed were hiding.

Can I play again?

One ticket is for one game. To play again, please buy another ticket.

Is my collection saved?

Yes. Open your game link (play code) to see your results anytime. The short video is not saved, so download it from the results screen.
