At GiftsQR we live off one specific kind of moment: someone scans a QR code and breaks into a smile. But not every moment needs to be emotional — some can be pure friendly trash talk. That's exactly what blocks.pw, our team's duel game, is for.
What is blocks.pw
blocks.pw is a 30-to-40-second duel game that runs entirely in the browser: no download, no app store, no account. Each duel draws a sequence of mini-games — reflex, smash, stack, memory, hunt, and more — and whoever takes 3 rounds out of 5 wins.
The clever part is the duel by link: you play your half, send the link on WhatsApp, and the other person plays whenever they can. The score settles itself, complete with a ready-made trash-talk message to share.
How to challenge someone in 3 steps
- Open blocks.pw/new on your phone.
- Play your sequence of mini-games (takes under a minute).
- Tap Share — whoever opens the link faces your score.
You can also play a quick match against opponents worldwide and climb your country's ELO leaderboard.
The QR code trick for parties
It pairs perfectly with what we do here: at parties and events, create the duel arena and turn the link into a QR code with our free QR code generator. Print it and leave it on the table — guests scan it and join the tournament without typing anything.
It combines especially well with:
- Digital invitations with RSVP — confirm your guests first, promote the tournament in the invite.
- Event photo album (Tunel) — guests upload party photos via QR while battling for the ranking.
- Countdown pages — for the birthday or wedding; the duel keeps everyone busy while they wait.
Why we built it
Same reason as our other products: shared moments shouldn't have friction. A gift shouldn't require international shipping (that's why GiftsQR exists), watching Brazilian TV shouldn't require living in Brazil (that's why Tunells exists) — and challenging a friend shouldn't require a 2 GB download. blocks.pw completes the family: meet all our projects.
