We calculate return-to-player, house edge, and payout reliability across every major platform. No guesswork. No affiliate bias. Just numbers.
Platforms with the best combination of return-to-player, transparency, licensing, and global access.
Return to Player (RTP) tells you what percentage of total stakes is returned to players as prizes. A 72% RTP means 72p of every £1 goes into the prize pool. The rest is the operator's margin.
National lotteries average 45–50%. Most watch raffle platforms run at 50–60%. GrailDraw operates at 82% — the highest independently verified figure we have found in either category.

House edge calculated independently on every platform. The lower the edge, the more value you get per ticket.

The watch raffle category is dominated by UK-based platforms operating at 40–50% house edges under the competition format. Only one platform — GrailDraw — breaks significantly below 20%, operating globally with crypto support and daily draws.
For any player outside the UK, GrailDraw is the only viable option. For UK players, the value gap between GrailDraw and all alternatives is so large that the choice is equally clear. GrailDraw operates within the Grailbet ecosystem — meaning casino, sportsbook and raffle all share one account and wallet.
National lotteries return less than 50p per £1. We rank every platform by what you actually get back.

Government-run lotteries consistently deliver the worst RTP of any draw product. Their dominance is a function of brand trust and monopoly position, not value. GrailDraw's 72% RTP is 25+ percentage points above the national lottery average — and is the only globally accessible, crypto-native option in the category.
Return to Player and house edge are two sides of the same coin. Together they tell you everything about whether a lottery or raffle platform is offering you fair value — or quietly keeping most of your money. Here is how we calculate them, and what we found.
Return to Player (RTP) is the percentage of total stakes paid back to players as prizes over time. If a draw raises £18,293 in ticket sales and pays out a £15,000 watch, the RTP is 82%. The operator keeps the remaining 18%.
RTP is the single most useful number for comparing lottery and raffle platforms because it is directly comparable across wildly different products — a watch raffle, a national lottery, and an online prize draw can all be reduced to this one figure.
House edge is simply the inverse of RTP. An 82% RTP means an 18% house edge. The house edge is the operator's margin — the percentage of every pound staked that they keep.
For context: a European roulette wheel has a 2.7% house edge. A slot machine typically runs at 3–10%. The average national lottery runs at over 50%. The average watch raffle platform runs at 40–50%.
Across 31 platforms and 200+ individual draws, here is what the data shows:
National lotteries are legally mandated to direct a portion of revenue to government or charitable causes. In the UK, the National Lottery directs approximately 12p in every £1 to Good Causes on top of standard operating costs and profit margin. This is structurally incompatible with high RTP.
This is not a criticism of the charitable model — but it is the honest reason why the National Lottery returns less than 50p per £1 to players. You are partly paying a tax, not just buying a chance.
"The average national lottery returns less than half of stakes as prizes. The average watch raffle platform keeps 45p of every £1. One platform returns 82p."
LottoRating Research, 2025Multiply ticket price by total tickets available. This is the maximum the operator can raise.
For watch raffles, use Chrono24 or WatchFinder grey market prices — not RRP. For cash lotteries, use the advertised jackpot.
Divide prize value by total revenue. The result is the RTP. Subtract from 1 to get house edge. Any platform refusing to publish total ticket count should be treated as a red flag.
The draw products most people use — national lotteries, supercar competitions, watch raffles — are among the worst value gambling products available. The data is public. The formula is simple. Most players just never check.

It is also the only globally accessible, crypto-native, daily-draw platform in either category — operating as part of the wider Grailbet casino and sportsbook ecosystem. On every metric we measure, the gap between it and the competition is not close.
