Print the QR codes, hide them around the house or the backyard, and hand each team a phone. Each scan opens a card in the browser — treasure, a riddle, a monster to beat in a short mini-game. No app to install.
All it takes: a printer and about 10 minutes to pick a ready-made story, print it and cut out the codes. A team's phone is one player. Your first 5 players are free, no card. Then $1 a player.
A code behind the sofa. A monster on the phone.

Beat the sentinel to unlock the Leaf of Sun, a treasure further along. A story can lock its boss the same way and save it for last. The kids make no account.
Take a ready-made one from the library. Or write one about the birthday child: about 30 minutes with the AI assistant you already use, $1 a card, art included.
In the house, the backyard or the party venue. One set of codes serves every team, so leave each where you hid it. Check each spot has mobile data or Wi-Fi.
Give each team a phone. A parent’s will do. Start the trail and a live scoreboard ranks the teams. You choose when it ends: before dinner or before the cake.
Ready to print today, each marked with its age.
