Zeus vs Hades at a glance

All values were read from the in-game information screen on Duel on the test date. Every Hades figure beats its Olympus counterpart, so on the maths alone Hades is the better half of this game at every mode. Configurations differ between casinos, so the information screen where you play is the number that counts — how to read it in a minute.

What this page proves — and what it doesn't

It proves nothing about the RTP: a hundred spins never do. It tests one deterministic claim — that Duel credits 50% of the house edge on every settled wager — by comparing the rakeback counter with the starting balance, ending balance and turnover. The rules are on the methodology page; this is the eleventh test in the series.

Six figures, one badge

Duel's rakeback tooltip for the game reads:

96.14% is neither base mode. Olympus plays at 96.05% and Hades at 96.07%; 96.14% is the Hades Buy Free Spins figure, the highest of the six the game publishes. This is the second time in the series the badge has quoted a feature buy, after Duck Hunters, and with six distinct values to choose from it is the least ambiguous example yet of the pattern: eleven games inspected, eleven badges equal to the game's best mode. "Duel RTP" is the interface's own aggregate of RTP plus rebate; we call that figure a conditional effective return, because the rebate accrues outside the game and has to be claimed.

How we tested

Starting balance $1,039.35, rakeback counter at zero. One block of 100 spins at $0.50 through Hyperplay in the base game, no feature buys — $50.00 of turnover. The game asks you to choose Olympus or Hades before play; as the results show, the accrual did not depend on the choice. Ending balance $1,015.90, total winnings $26.55; the ledger reconciles to the cent: 1,039.35 − 50.00 + 26.55 = 1,015.90. The per-spin Hyperplay table is archived as evidence.

Results: the cents pick the badge over both base modes

Whichever base mode a player runs, the mode-based prediction overshoots what accrued, and the badge's figure hits it exactly. The rakeback engine runs one flat rate per game — the badge's — regardless of the mode you play. The flip side in plain words: with mode RTPs spanning 96.01–96.14% and the accrual pinned to 96.14%, playing this game's lower-RTP modes leaves the widest gap in the series between your real edge and the edge your rebate is computed from. Hundredths of a point, pennies at these stakes, and a principle that scales with volume.

What it costs across the modes

The rebate is the same 1.93% of turnover in every mode, because it runs off the badge. That makes Zeus vs Hades the most expensive Pragmatic Play title in our series after the rebate — Sweet Bonanza 1000 nets 1.73%, Gates of Olympus 1000 1.75%. Halved is still not cheap: a low-edge table game costs less. Whatever the mode, the cost is (edge − rebate) × turnover; the rakeback guide has the arithmetic for any game.

Session outcome: 53.1%

The block paid back $26.55 on $50.00 wagered. Eleven sessions in the series now span 26.5% to 593.2%, and none of those figures estimates the long-run RTP of any game. The constant across all eleven is the rakeback, which has landed on its predicted value every time. Accrual tracks turnover, not outcomes.

Limits of the evidence

One account, one date, USDT, with the 50% badge active — rates could differ by account, region or time, and Duel's terms can change after publication. The conclusions cover the accrual formula only, not session outcomes. The best-mode pattern is an observed regularity across eleven games, not a documented Duel policy, and cent-level data can separate candidate figures only when their predictions land in different display values on the tested turnover — as they did here.

Verdict

On this account, on this date, Zeus vs Hades accrued instant rakeback at exactly the badge's flat rate across the tested block — matched to the cent, with both base-mode predictions ruled out by the same cents. The advertised number checks out, the badge's figure is verifiably the best of the game's six modes, and the series' central finding rests on its cleanest example.
