Every lottery pool argument in the news comes down to a question nobody wrote down. Was Sam in this week? Did Maria pay for one share or two? Who has the ticket? Did John buy the extra line for himself or for the group?
Here are the eight rules that answer those questions in advance, and where each one lives in a ShareTheWinning pool. Agree on them before the first dollar changes hands. It takes five minutes.
1. Who buys the tickets
One person buys, every time. Not whoever is passing the store. If the buyer is away, a named backup buys. A pool with two buyers ends up with two tickets and an argument about which one was the pool’s.
In the pool: the Pool Admin buys at a licensed retailer in the pool’s state and records every ticket. The agreement names a successor admin who may act if the admin cannot be reached. The game and the state are fixed when the pool is created.
2. Who signs and holds the ticket
The buyer keeps the ticket somewhere safe from the moment it is bought. A lottery ticket pays whoever holds it, so who signs it matters, and each lottery says how a group should sign and claim. In Wisconsin, for example: Wisconsin pays one claimant; the agreement names who claims and how the pool splits it. One person signs a group ticket and the Wisconsin Lottery pays that claimant; paying several winners on one ticket takes a court order. (Wisconsin Lottery FAQ, checked Oct 1, 2026) Your state’s page says what your lottery asks for. Whatever it is, the rules name the person in advance.
In the pool: the agreement says the Pool Admin holds the ticket and claims on behalf of the members in the locked snapshot. The ticket photo, with the time it was recorded (our server’s clock, not the phone’s) and a fingerprint of the file, is the pool’s proof of which ticket is the pool’s.
3. How shares work
Decide the price of one share and whether a person may buy more than one. If Maria pays $20 and everyone else pays $10, Maria owns two shares and gets two tenths of the prize, not one ninth. Say so.
In the pool: the admin sets the price per share and the maximum shares per member. A share is a unit of what a member puts in and what they own; it does not have to buy exactly one play. With $5 shares and $2 plays, ten shares make a $50 pot that buys 25 plays, and every share owns the same slice of all 25. Your share of any prize is your shares divided by all shares in the snapshot for that drawing. The split is by shares only; there is no other formula to argue about.
4. The deadline to pay
Money is owed before the ticket is bought, never after. Pick a time: “by 5 p.m. Friday” or “an hour before sales close.” Whoever has not paid by then is not in that drawing.
In the pool: every round has a lock time. By default it is 60 minutes before the state’s sales cutoff for the drawing, so the admin has time to buy. Members mark their payment, the admin confirms it, and at the lock the members, shares and confirmed payments freeze into a snapshot that cannot be edited. Members get a reminder before the lock.
5. What happens to latecomers
This is the rule that saves friendships. Someone says “I’m in” on Tuesday and pays on Thursday, after the drawing. Are they in? Write the answer down before it happens.
In the pool: the agreement states the policy. The default is that an unconfirmed share is dropped: the person is not part of that drawing and is owed nothing from it. The alternative, which the admin can choose when creating the pool, is that the admin covers the share and the member owes the admin the share price. Either way the answer was written before the drawing, and the snapshot shows it.
6. How numbers are shared before the drawing
Every member should see every line of numbers before the balls drop. A photo in a group chat is good. A photo that cannot be changed, recorded with the time a server received it, is better: the time a phone says a photo was taken can be edited, the time it was recorded cannot. If the organizer plays personal lines too, they must be on a separate ticket.
In the pool: the admin uploads the ticket photo first, then types the plays, before the drawing. Every member can see every ticket. A ticket recorded after the drawing time (by our server’s clock) carries a permanent “recorded after drawing” flag and puts the round on review. Members can confirm that the photo matches the typed plays, and the ticket shows “Member-confirmed” once two members other than the person who recorded it have done so (in a two-person pool, the other member). Member-confirmed says the record matches the ticket; the official ticket and the lottery still decide every prize.
7. Who claims
How a group claims depends on the state’s lottery. Some pay one person per ticket. In Texas: Texas pays one claimant; the agreement names who claims and how the pool splits it. The Texas Lottery pays one claimant per ticket, so a group names one person to claim. (Texas Lottery FAQ, checked Oct 5, 2026) Others publish a group process with forms for every member. In California: The pool agreement names who claims. The California Lottery publishes a group claim process: from $600 to $999,999 one member claims for the group with Claim Form CSL1242 and IRS Form 5754; at $1 million and up the group representative completes form CSL 0896 and every other member completes CSL 0897. (California Lottery claim page, checked Oct 8, 2026) Either way, name the person who claims in advance, name a backup, and agree that large prizes wait for a lawyer and an accountant before anyone goes to the lottery office. Where one person claims for the group, the claimant hands the lottery IRS Form 5754 listing every member and their share, and the lottery issues each person their own Form W-2G.
In the pool: the agreement names the Pool Admin as claimant and a successor who may act after 72 hours of silence; your state’s page says how its lottery pays a group. When a prize crosses the state’s threshold the round goes on hold and the pool builds an export bundle: the snapshot, the agreement, the ticket photos with their fingerprints, every play and the official result. How a pool claims a prize walks through the rest.
8. How winnings are split and paid
Agree on two things: the split (by shares) and the mechanics (who pays whom, how, and by when). Decide what happens to small prizes: pay out a $4 win to ten people, or roll it into next week’s tickets? Decide whether the pool takes the lump sum or the annuity on a jackpot. Decide what happens if the admin bought more or fewer plays than the pot covered.
In the pool: payouts are the prize times each member’s shares divided by all shares, in cents, with leftover cents assigned by largest remainder and shown in the record. The admin records each payment, the member confirms it, and the round closes when every line is settled. The admin can set a small-prize rollover amount when creating the pool, and the agreement says so. Money never moves through ShareTheWinning; the ledger shows who owes whom. Ten friends, one jackpot shows the split to the cent.
The rule behind the rules
Write it down before, not after. Every one of the eight rules above is cheap to agree on while the jackpot is a daydream and impossible to agree on when it is real. That is why a ShareTheWinning pool asks for these answers when the pool is created and puts them into a short agreement every member accepts before their first share. The pool agreement, explained walks through that text clause by clause.
The “Play it” stop on the Journey lets you set a pool size, share price and share count and see the pot and the cost per person before you invite anyone.
