For organizers

Tap Create a pool, choose Classic or Auction, pick the sport and enter the two team names, set your price per square (classic) or starting bid (auction), choose how the pot is split, add the payment methods you'll collect with, and share the link. You can change anything later from Manage.
Every pool has a share link. Public pools let anyone with the link join; private pools also require a join code (shown on your Create/Manage screen) that you send separately. Players paste the link — and the code, if private — on the Join screen.
In a classic pool the pot is your price per square times the squares actually claimed; in an auction it's the sum of the winning bids. A pool doesn't have to sell all 100 squares — unsold squares just stay empty, and each period's payout is based on what's been claimed.
On Create (or Manage) choose how the pot is divided: by period (e.g. Q1/Q2/Q3/Q4/Final percentages, with Split evenly and sport presets to start fast) or per scoring play. By-period percentages must add up to 100%.
Add your payment handles (Venmo, PayPal, Cash App, Zelle) when you set up the pool, then mark each player paid on the Manage screen. Everyone sees the running paid/owed totals.
Once the squares are filled — usually right before kickoff — lock the pool from Manage and draw the numbers. Until you draw, each row and column shows a ? so nobody can game the board.
Enter each period's score on the Manage screen as the game goes. 100boxes finds the winning square from the trailing digits of the score and calculates the payout automatically.
Yes — open Manage to change team names, dates, pricing, the message to players, and payment methods. A few things lock once the numbers are drawn.
Yes. Share the invite link anywhere, and use Print on the board for a paper copy on game day.
As many as you like. Your Dashboard lists every pool you organize or have joined.
Yes. When you create a pool, turn on "Benefit a charity" and set the charity's name, a short description of the donation, and the percentage of the pot (1–100%) that goes to the charity.
The charity gets its percentage off the top of the pot, and the winners split the rest using your normal payout split. For example, on a $100 pot with a 50% donation, $50 goes to the charity and the winners split the remaining $50.

For players

Tap Join a pool, paste the invite link the organizer sent you, and enter the join code if it's a private pool. You'll land right on the board.
In a classic pool, tap any open square on the board to claim it (you can add a short message). In an auction pool, place a bid on the squares you want.
In an auction, the highest bid on each square when the auction closes wins it. If someone outbids you, you're notified instantly so you can bid again before it closes.
Yes — a quick sign-in keeps your squares and pools saved to you. You can sign in with email or a social login.
You can get alerts for new players, outbid alerts, score updates, winner announcements, and a heads-up before a pool locks. Manage them anytime in your Profile.

General

Each pool is a 10×10 grid of 100 squares. Players claim squares before the game. Once the pool closes, a random digit 0–9 is assigned to each row and column. Your square wins if the last digit of each team's score matches your row and column at the end of a quarter.
100boxes tracks who's paid and who owes — you collect however you like (Venmo, cash, PayPal). Mark a player as paid from the Manage screen and everyone can see the running totals.
The organizer locks the pool (usually right before kickoff), then draws the numbers. Until then squares show a ? on each axis so nobody can game the board.
You set a payout split across Q1–Q4 (and/or Final). At the end of each scoring period, the winning square is found from the trailing digits of the score, and the payout is calculated automatically.
In an auction pool the numbers are shown up front and players bid on the squares they want. The highest bid on each square when the auction closes wins it — outbid someone and they get notified instantly. Great when everyone wants the same hot numbers.
Yes — football, basketball, hockey, soccer, anything with a running score. You set the team names and the scoring periods.
Yes. Creating and running pools is free. Money for squares goes directly between you and your players.
100boxes never touches your money. You collect from players however you like — Venmo, PayPal, Cash App, Zelle, or cash — and we just track who's paid and who owes. We don't process payments or store any card details.
No. 100boxes shows the donation amount so everyone can see it; the organizer collects the pot and donates the charity's share themselves, the same way all other payouts work.
