How to Check Slot RTP on Duel

Step 1

1Open the Exact Game

Find the slot in the Duel lobby and open its page. Check the full title: The Dog House, The Dog House Megaways and The Dog House Megaways 1000 are three games with three badges (3.49%, 3.45% and 3.50% when we checked), and Gates of Olympus 1000 is not Gates of Olympus Super Scatter. The page also names the studio and the category; make sure the category says Slots — live games and game shows carry a margin too, and it means something different.

Step 2

2Read the Badge

Below the title Duel shows a percentage. It is the house edge, not the RTP — the share of turnover the game keeps over the long run. Note it exactly as printed: 3.45% is not 3.5%, and the difference matters when you compare games that sit a few hundredths apart. If the page shows no figure, or you cannot open it from your country, the check stops here; a number from a review site is not a substitute, because studios ship several RTP versions and Duel's may not be the one the review saw.

Step 3

3Turn the Badge Into RTP

Implied RTP = 100% − badge edge

All 32 games we checked sit inside that range — under one percentage point from top to bottom. The arithmetic is the easy part; the next two steps are where the figure can mislead.

Step 4

4Open the Information Screen

Inside the game, the rules or information screen lists the RTP — often several: base play, an ante bet, one or more feature buys. Read all of them. On every game where we read the full list — nine of the eleven we tested — the badge matched the highest figure on it, not the base game. Sweet Bonanza 1000 shows 96.55% on the badge and 96.53% for base play; Duck Hunters lists nine modes and the badge quotes the best of them. So the badge tells you the RTP of the game's best mode; the information screen tells you the RTP of the mode you are about to play.

Step 5

5If the Badge and the Rules Disagree

Sooner or later step 4 gives you two figures for one game. We hit this repeatedly across the eleven tests, and every case fell into one of three types. Work through them in order.

Type 1 — the same number at different precision

On Fist of Destruction the badge showed 96.35% and the rules printed 96.3%. Not a disagreement: one decimal against two, both correct roundings of one value. Compare precision before anything else. Hacksaw Gaming in particular prints RTP at one decimal in one place and two in another. The test shows the rakeback landing exactly where the shared figure predicts.

Type 2 — the badge is quoting a different mode

This explains most apparent gaps. On Duck Hunters the badge's 96.07% was not the 96.05% base game; it was the Hawk Eye feature buy, the best of nine listed configurations. Scan the whole mode list before calling anything a contradiction.

Type 3 — a real gap

On Le Bandit the rules said 96.34% and the badge 96.4%, and 96.34 does not round to 96.4 at any precision. The two sources genuinely disagreed; in our test the rakeback followed the badge. When you find one of these, keep both figures and where each came from — and expect your rebate to be calculated from the badge.

Order of operationsCompare decimals first, then read the full mode list, and only then treat a mismatch as unexplained. Across the nine tested games where the full mode list was read, the badge equalled the highest published mode every time; the pattern is documented on the methodology page.

Step 6

6Take Off the Rakeback

Duel credits half of the badge figure back to you on every dollar wagered, instantly and — in all eleven of our tests — withdrawable without a wagering requirement. The cost you actually carry is therefore the other half:

Net cost = badge × 50%

A 3.50% badge is a 96.50% game with a 1.75% net cost, or an effective RTP of 98.25%. The rebate is computed from the badge whichever mode you play, so on a lower-RTP mode your real cost slightly exceeds the figure the rebate is based on — a difference of hundredths of a point on the games we checked. The full arithmetic and the test table are on the rakeback guide; the calculator below does the sums for any figure.

Pitfalls

Five Ways the Check Goes Wrong

1. The wrong version

Base, 1000, Megaways, Super Scatter — same brand, different games, different badges. Read the exact title.

2. Reading the badge as the RTP

It is the edge. 3.45% on the badge is a 96.55% game, not a 3.45% one.

3. Reading the badge as the base game

It is usually the best mode. Base play can sit a few hundredths lower; the information screen says by how much.

4. Taking a figure from a review instead of the page

Studios ship several RTP versions of a title. A review saw one casino's version; Duel may run another. Even Duel's own badge and rules screen can differ, as step 5 shows — a review number is two steps further from the truth than either.

5. Treating the result as a forecast

RTP is the average over millions of spins. A session can finish anywhere, and the rakeback moves the outcome by the same small percentage either way.
