• Book of Dead counts toward BetFlag's slot welcome offer, and the proof is that BetFlag left it out of the exclusion list.
• That list names seventeen slots. One of them is another Play'n GO title, 1429 Uncharted Seas, so leaving this one in was a decision rather than an oversight.
• The offer is a cashback on how much you play, not a match on what you deposit. Put in 10 euro, play 400 euro in slots, and 10 euro lands on your balance.
• The site runs under ADM concession 16008, held by Betflag S.p.a. Its own footer still shows the older 15007.
• What BetFlag publishes about this game stops short of a contribution percentage. It publishes eligibility, and this page stops exactly where BetFlag stops.

Deposits That Unlock the Cashback

Figures current as of 30 Sep 2026; the operator's live terms prevail.

Welcome Cashback Terms at BetFlag

Eligible Because It Is Absent

BetFlag skips the percentage and publishes something narrower and, for once, more useful: the list of slots excluded from the offer.

Seventeen titles are named, from 1429 Uncharted Seas through Sweet Dream, and the wording is plain. Only slot play with cash balance counts, minus those seventeen. All seventeen are named, and this title sits outside the list.

The detail that turns this from an accident into a decision is the first name on the list. 1429 Uncharted Seas is a Play'n GO game, the same studio. BetFlag went through its catalogue, pulled out one Play'n GO title, and left this one in.

How Much the Cashback Actually Pays

It pays back your deposit, once you have played roughly forty times that deposit in slots. Ten euro in, four hundred euro of slot wagering, ten euro credited.

Then it asks for one more pass. Every tier you unlock has to be played through once before it becomes money you can take out.

Read the shape of that before the size of it. A cashback on volume is a different promise from a deposit match, and the number that decides whether it is worth your time is the 40x, not the 5, 10 or 15 euro at the end.

The Win BetFlag Reported

BetFlag once ran a news item about a player who took 100,000 euro on this slot. It was March 2019, it was one player, and it is the only figure BetFlag attaches to this game.

Read it as one player's result on one day, rather than as a ceiling or a typical outcome. The ceiling Play'n GO itself states is 250,000 coins, which is 5,000 times your stake once all ten lines are live. What one player took on one night tells you nothing about what the next spin does.

Gaps in What BetFlag Publishes

Return figure: absent. Stake range: absent. Demo statement: absent. Withdrawal minimum: absent. BetFlag's terms, which we did read in full, say nothing about demo mode at all.

One more caveat belongs here rather than buried. The most recent copy of BetFlag's game page we hold is from April 2025; the live one stayed shut to us. Treat the listing as likely rather than certain, and search the lobby yourself before you count on it.

Who Actually Runs BetFlag

The concession is 16008 and the holder is Betflag S.p.a. The footer still shows 15007, which Italy's 2025 re-tender replaced.

There is a second thread worth knowing. The VAT number BetFlag publishes as its own resolves to Gruppo Lottomatica, the group that also stands behind Goldbet and Lottomatica. If you are picking operators to spread risk across, that is the kind of link worth checking first.
