OVRLND gives away vehicles: a restored Bronco, a Tacoma, a 1985 Toyota pickup. Customers buy gear and entry packs, and every dollar buys ten entries. When I rebuilt its retention plan in July 2026, the diagnosis took one sentence. The company had already built a game, and its email program wasn't playing it.

The game had four parts. A currency: $1 buys 10 entries. A status ladder: membership tiers from Bronze to Platinum. A recurring event: weekly draws for members. And proof people win: real winners, drawn live. That's a complete loop engine, the same one Whatnot runs with auctions and giveaways and Binance ran with tiers and token sales.

The welcome flow, meanwhile, ended in a coupon ladder: 25% off membership, then 50%.

The game earned roughly two hundred times the coupon

ReportedDifferent flows reach different people at different stages, so read the order, not the ratios. The Tacoma figure was earned when orders averaged $35 to $45, not the $22 to $24 of mid-2026.

The coupon tail earned $237 on 27,326 sends. The receipt that simply told buyers how many entries they had just locked earned more per person than anything else in the account. It had no discount in it and, at first, not even a number.

A discount ends the game. A scoreboard keeps it going.

Give the game a scoreboard

The plan was one idea executed everywhere: show players their score. Three rules made the scoreboard work for the business and stay honest with the customer.

1. Show progress, not claims about oddsShow the customer's stack, how much it moved and their rank: "+620 entries locked, you passed 1,200 players." Every one of those numbers can be checked against the customer's own orders. Odds and total-entry counts live in the official rules, where the law puts them, and nowhere in marketing, because every number in a sweepstakes email is a representation that has to be exactly true.
2. The score appears only when it movesA balance that just changed is news. The same balance re-sent every week is wallpaper. Counts earn a subject line only on movement.
3. The lifetime score never resetsEach giveaway ends, and most players lose. Lifetime entries survive the loss. They turn a draw into a chapter instead of an ending, and they're what the next giveaway builds on.

Nir Eyal's Hooked names the last step of a habit loop investment: something the user puts in that makes the next trigger more likely. Lifetime entries are exactly that. A player with 1,860 lifetime entries has something to lose by not coming back.

Every mechanic is a legal structure

In the US, a prize, a chance and a required purchase together make a lottery, which private companies can't run. Sweepstakes stay legal by giving a free alternative method of entry with equal standing. That's why Whatnot's Buyer Appreciation Giveaways carry a free web form, and why every OVRLND mechanic went to counsel before it shipped.

The review turned that into a design rule: in a paid sweepstakes, every mechanic is a legal structure and every displayed number is a representation. Compliance is a design input, not a sign-off at the end. Three examples from the plan:

• The Sealed Envelope, a welcome surprise, is one per customer for life, a fixed amount identical for everyone, disclosed in the official rules with a free path to the same grant. The mystery lives in the copy, never in the mechanics. A random bonus on a purchase is a second lottery.
• The referral bonus ships only when the next giveaway's rules include it, with a free way to earn the same entries.
• No rules change mid-cycle, ever. What isn't in the rules before entries open ships as a non-entry perk, or waits.

What not to add

The plan's list of cuts was as long as its list of plays. No entry multipliers in flows. No bolt-on points, badges or spin-wheels: entries already are the points. One device per moment: the entries receipt stays in post-purchase, where it's true, instead of being pasted into every flow until it means nothing.

You don't need a sweepstakes to use this. Any brand with repeat purchase can find its currency (points that buy something real, progress toward a product), its ladder, its recurring event (a monthly drop, a weekly restock) and its proof (real customers, named with permission). Most already have three of the four and bury them under discounts.

Do this

• Write down your currency, ladder, recurring event and proof. Mark any that don't exist yet.
• Build one receipt that shows the customer's score moving after each purchase, and put the share link on it.
