It's the thrill of the night. We hope! It's a mobile web game designed specifically for our 25th Reunion. Insert a quarter-sized ID Chip in your jacket's tracker pocket to play. Scan your classmates to log your interactions and score points to keep a private record of how you showed up at Reunions. At the end of the weekend, your beer-logged, 40-something mind may not remember all the great interactions you had, but your Player '01 Journal will. There's no loss condition in this game, even if you lose your jacket: anyone else can scan it to help return it to you. And, as in life, everyone who shows up to Reunions automatically wins.

No. Participation is voluntary. You can choose full engagement, use your ID Chip only for jacket recovery, or opt out entirely. If you opt out, you can even be playful without playing by setting a custom message for anyone who scans you — maybe "These are not the Tigers you are looking for." or "In the nation's service and in the service of all humanity, I'm not playing."

Visit hiofthetiger.com. Select the button that matches your current state: at home, at registration, or confused.

• If you're at home, you'll enter your phone number and set up your profile.
• If you're at registration, you'll scan your new NFC, then be prompted to enter your phone number. If you already signed up at home, the game will confirm it has your phone number and give you the opportunity to visit your profile page.
• On your profile page, you'll find fields for your residential college, eating club, major, activities, and a few other things that might jog someone else's memory — or your own.
• Once you've received and scanned your ID Chip, insert it into your jacket's tracker pocket. That's it. You're ready to play Hi of the Tiger and scan any tigers you connect with.

You can find the full schedule here. And if you're enjoying this game experience, please check out Choose-Your-‘01-Adventure, playing in Whitman Theatre on Friday at 1pm, 2pm, 3pm and 4pm and on Saturday at 10am, 11am and 12pm. You can relive 1997–2001 on the Princeton campus, making all new choices.

Tap here to sign out. You'll need your phone number to sign back in.

Anyone with an NFC tag can be scanned. To scan tags, the game requires a smartphone with NFC capability. Most phones made after 2018 support NFC. If you're not sure whether yours does, go to Settings and search "NFC." If it appears, you're good. If you're having trouble scanning, ask a nearby classmate — rumor has it, they're smart.

No. If your VPN is on, the game will not recognize you as a registered player and will treat you as if you're not a member of the Class of 2001—the horror! Turn it off before playing.

Yes, but not the entire time. You need a data connection (WiFi or cellular) to log scans and access your journal. Princeton's campus has WiFi — connect to PUVisitor (or whichever network '26 Reunions materials recommend) or use your cellular data. The game is set up so that your phone will retain data if you lose connection — any scans you log while offline will sync automatically when your connection returns.

No. Hi of the Tiger does not track your location at any time. Your ID Chip stores only a random ID number — not your name, not your location. Scans only happen when you actively hold your phone to someone's chip or they hold their phone to yours. Nothing is passive or automatic. This also means that there's no "Find My Jacket" functionality — an AirTag is required for that, and there's a pocket in your jacket that fits one if you'd like to add your own. Our recovery method relies on NFCs and the kindness of Tigers.

Yes. Your phone number is used only for account authentication and game notifications. It is never sold, shared, or used for marketing. It's not even shared with classmates when you share your profile (which you customize). You may opt to share your number with the relevant party if you find or lose a jacket. You can read our full Privacy Policy at hiofthetiger.com/privacy.

It's a small NFC sticker that fits in the tracker pocket of your class blazer. NFC stands for Near Field Communication — it's the same technology as Apple Pay and Google Pay, only we're not asking you to pay. Your chip stores a unique random ID that links to your game profile. No personal information is stored on the chip itself.

Ask their consent — that's part of the game. Then hold the top of your phone to where their jacket's tracker pocket is (assuming it's holding the ID Chip—if it's not, scan wherever the ID Chip is). Your phone will automatically open the game and you can log the interaction with one touch. No app download required.

When you scan a classmate, you'll be asked how you approached them: knowingly, imperfectly, daringly, generously. Here are some examples of what might qualify for each:

This is by no means an exhaustive list. Use your best judgement — and the knowledge that, much like the '80s slogan of our favorite orange-wrappered binary treat, there's no wrong way to approach a classmate.

Your selection of how you've approached classmates determines your tiger type scores. We've tried to correlate them to the personality of wild (and mascot) tigers… without knowing many of these tigers personally.

Your '01 Player Journal shows your totals across all four types at the end of the weekend—and throughout the weekend, allowing you to reflect on how you've shown up and to take pride in being an active tiger.

Your Player Journal is a personal recap of your Reunions weekend. It's private — only you can see it. Your journal shows your tiger type totals, any lost jacket events, and a list of every classmate you scanned with links to their profiles — which contain facts you may forget after beer (or 25 years) and topics to connect around at the Watering Hole and even after Reunions. Think of it as a keepsake of how you showed up and who you shared time with.

It's where you get free beer (that you've paid for with dues and fees). In your profile, it's the section that goes beyond the facts and helps surface topics for conversation and connection, at Reunions and beyond.

You're encouraged to include things you're knowledgeable about — personally and professionally — after 25 years of Leveling Up, passions and interests you'd welcome the opportunity to discuss, and your invitations and offers. This section is optional but encouraged and only visible to classmates who scan you.

Sometimes there are things that don't come up at the beer tent but would be great to connect about later—if only you knew that person had a connection to that topic. And sometimes you think you've covered everything in the first conversation—but if you check what's in the Watering Hole, maybe you'll discover there's a treasure trove of things you'd love to discuss if you're lucky enough to come across that tiger again.

You don't find it — it finds you. If someone discovers your jacket, they can scan your ID Chip in the tracker pocket and send you a notification through the app. That notification appears as a glowing jacket icon in your Player Journal. You'll see any message they left, their HQ drop-off plan, and — if they chose to share it — their contact info.

Finders will always be provided with the default option to return your jacket to 25th Reunion HQ — and will be asked to provide an ETA — regardless of whether they choose to share their contact information.

Go to your Player Journal, click the jacket entry, and confirm you've received your jacket. This lets the finder know you're no longer going nuts and sends a thank-you note to your Good Sumatran's journal, if they're a player.

Someone who found your jacket and helped return it. Sumatran is one of the rarest tiger subspecies — here representing who we might otherwise call a Good Samaritan.

They go up in smoke. Kidding! They get added to your list of Cubs Chuffed, which is separate from your list of classmates with whom you’ve reconnected. Let’s be clear: honorary ’01 is not the same as ’01! Student crew members will only be able to see your name and Princeton-related information (Residential College, Eating Club, etc.), not anything you’ve included for Watering Hole conversations. However, you’ll be able to view all of their profile information. Is this unfair? Well, it’s our Reunion… (Seriously, though, student workers choose what to include, and this way if you’re inclined to mentor someone, you’ll know what they’re interested in.)

That's Juniper Sowden (Class of ’31 if we’re lucky enough to get her!), the talented daughter of classmate Jessica Williams.
