Built for Game Day.
Built to Last.
Football squares have been a tradition for decades. We just made it work on your phone.
The fastest setup. The best game day. Your crew, every season.
What GridBlitz Does — and Doesn’t Do
GridBlitz is a coordination platform. We organize the Grid, assign the numbers, and track the scores. Everything else is between you and your group. Here’s the line:
What it does
Creates and manages Grids — 10x10 Grid setup, player invites, Square tracking. The digital equivalent of a paper grid.
Assigns random numbers — Cryptographic shuffle after the Grid locks. One-time, irreversible, nobody peeks.
Tracks live scores — Real-time score updates show which Square matches the current score at each quarter.
Highlights Score Matches — When a Square’s two numbers match the score, it lights up. We call it a “Score Match” — not a winner.
What it doesn’t
Does NOT determine outcomes — We show data. What your group does with it is your call.
Does NOT handle payments between players — Entry fees, distributions, arrangements — that’s between participants. GridBlitz is not involved.
Does NOT announce results — No “winner” language anywhere. No “prize” calculations. We show the Grid; you read it.
Does NOT facilitate gambling — GridBlitz charges hosts a platform fee for the software. We have zero involvement in money between participants.
Built on Trust
Secure Checkout
When a host buys Grids, Stripe handles the card — PCI Level 1 certified. We never see or store your card number.
Provably Fair
Numbers are assigned with a cryptographic shuffle after the Grid locks. No one picks, no one peeks. Same time, every time.
Privacy by Default
No public profiles. No follower counts. No player directories. Your games are your business. We collect only what’s needed to run the Grid.
A Coordination Platform, Not the Decider
We organize the Grid, draw the numbers, and track the score. We never decide anything about the outcome, announce results, or touch money between you and your group. You read the Grid; your crew takes it from there.
Hosts Are in Control
Your Grid, your rules. The host decides who’s in, how many Squares each person can hold, and anything about money — offline, between the host and the group. GridBlitz hands the host the tools and stays out of the rest.
