The Instant Game Is Designed Around Its Prize Table
A scratch card is a printed product with a predetermined distribution of winners, published in advance. The design decisions behind that distribution determine how the game sells and what the state earns from it.
A Finite Deck, Not a Random Draw
A draw game selects numbers at random, so the number of winners is unknown until it happens. An instant game works differently: a fixed print run is produced containing a predetermined number of winning tickets at each prize level, distributed through the run.
The outcome of every ticket is decided at printing. Buying one is drawing from a finite deck with a known composition rather than sampling a random process.
That composition is published. Lotteries disclose the number of tickets printed, the number of prizes at each level, and the overall odds, which makes this one of the few gambling products where the complete distribution is available before purchase.
The Numbers That Define a Game
| Parameter | What It Controls |
|---|---|
| Ticket price | Revenue per ticket and prize budget available |
| Payout percentage | Share of sales returned as prizes |
| Overall odds | Frequency of any win |
| Top prize size | Advertising appeal |
| Prize distribution shape | How the payout budget is spread |
The payout percentage is the constraint everything else operates within. Higher priced tickets generally carry higher payout percentages, commonly rising from around sixty percent on low price games to above seventy five percent on premium ones.
That relationship is deliberate. A player spending more per ticket receives a better return, which makes higher price points attractive and raises revenue per transaction.
The payout percentage is fixed by policy, so every design choice is a decision about how to distribute a budget that cannot grow. A larger top prize means fewer or smaller wins everywhere else, and both are things players notice.
The Tension in the Prize Structure
Two player behaviours pull the design in opposite directions.
Small frequent wins sustain play. A player who wins a few dollars back frequently continues buying, and a substantial share of low tier prizes are redeemed immediately for more tickets, which the industry tracks explicitly. Break even prizes returning the ticket price are a well known and heavily used design element for exactly this reason.
A large top prize drives initial purchase and advertising. It is what appears on the ticket and in marketing, and it is what makes a game feel worth playing.
Both consume the same budget. A game weighted toward frequent small wins has a modest top prize and sustains play poorly at the point of first purchase. A game weighted toward an enormous top prize produces long losing streaks that end play.
The resolution is generally a barbell: a meaningful number of low tier prizes at or near the ticket price to sustain engagement, a very small number of large prizes for marketing, and relatively little in the middle.
The Disclosure That Matters
Because the deck is finite, the composition changes as tickets are sold. A game whose top prizes have all been claimed is materially different from the same game at launch, since the remaining tickets carry a lower expected value against the same price.
Lotteries publish remaining prize counts by game for this reason, and the data is available to anyone who looks. Games with all top prizes claimed continue to be sold until the print run is exhausted or the game is closed.
This is disclosed and it is not prominent at the point of sale, where the ticket still displays the original top prize. Whether a display should be required to show remaining prizes is a live consumer protection question in several jurisdictions.
Who Plays and What That Means
Research on lottery participation consistently finds that spending as a share of income is substantially higher among lower income households, and that instant games in particular skew that way relative to large jackpot draw games.
Since lottery revenue funds public spending, frequently education, the resulting flow is a transfer from a player base weighted toward lower income households to a general public benefit.
Defenders note that participation is voluntary and that the product is entertainment. Critics note that the alternative revenue source, general taxation, is designed to be progressive and this is not.
Both positions are held seriously, and the design element that sharpens the criticism is that the games most heavily marketed and most frequently purchased are the ones with the least favourable payout percentages.
The Operating Economics
For a state lottery, instant games typically generate the majority of sales, and the operation is largely outsourced. Specialist companies print the tickets, provide the terminals and validation systems, and in some jurisdictions manage the entire operation under a contract taking a percentage of sales.
Retailers receive a commission on sales plus a bonus on selling a top prize winning ticket, which is a genuine incentive and produces the recurring practice of promoting where a large winner was previously sold.
The Bottom Line
A scratch card is a manufactured product with a published, finite prize distribution, and designing one is an exercise in dividing a fixed payout budget between the frequent small wins that sustain play and the large top prize that sells the game. The information available to a player is unusually complete and almost never consulted, particularly the remaining prize data that determines whether a game is still worth what it was at launch. The distributional pattern of who buys them is well documented and is the core of every serious argument about the product.
