There is no rule that says “show a percentage”. There are rules that make hiding the odds risky, and they give you a checklist.
What the code says
- Rule 8.20: “promoters must not exaggerate consumers’ chances of winning prizes”.
- The guidance wants a realistic indication of chances so consumers can decide whether entering is worthwhile.
- Ads should state the number of prizes likely to be awarded.
- Where it affects whether people take part, ads should explain how winners are selected.

A fair comparison
- Tickets available. A cap, or the number sold so far.
- Prizes and counts. Every prize, not the headline.
- Chance per ticket. “1 in N”, not “win big!”.
- Selection. How the winner is picked.
What Hoardsy publishes
Every competition page shows the prizes and the chance per ticket, and the draw-only prize pages show the ticket cap. For example, see £500 cash and Plinko odds explained.
How Hoardsy runs its competitions
- Closing dates are never extended for slow sales.
- There’s no minimum number of sales: every end-draw prize and top instant prize is awarded, sold out or not.
- Every competition page shows its prizes and your chance per ticket before you enter.
- Every competition can be entered free by post, with the same chances as a paid ticket. See free postal entry.
