FatBoss shows its welcome offer in kroner on the site, 3 500 kr plus 100 free spins, while AskGamblers lists a euro version of 100% up to EUR 50 plus 100 bonus spins, followed by 50% up to EUR 100 and 50% up to EUR 200. The bonus terms explain why the figure differs: the welcome bonus depends on the country you registered from. What they fix for everyone is 30x wagering on deposit plus bonus, a 3-day claim window, 30 days to finish and a 50 kr bet limit. Live casino and table games count nothing.

3 500 kr in one place, EUR 50 in another

The banner on the FatBoss site reads 3 500 kr Welcome Bonus and 100 Free Spins. AskGamblers lists the first deposit as 100% up to EUR 50 plus 100 bonus spins, the second as 50% up to EUR 100 and the third as 50% up to EUR 200. The bonus terms say only that the welcome bonus you are entitled to depends on the country of registration and that it is shown on the promotions page.

At those percentages the caps fill at a EUR 50 deposit for step one, EUR 200 for step two and EUR 400 for step three, so the three steps add up to EUR 350 of bonus at most. Neither the game for the spins nor the value of a spin is stated. Welcome bonuses may be granted at the casino's sole discretion, and the welcome bonus is not valid for players from 25 named countries including the UK and the USA, or for Germans who deposit with Neteller or Skrill. The terms of service add a separate list of 30 markets, among them Norway, Sweden and Brazil, where winnings from a claimed bonus can be voided.

30x on deposit plus bonus, with the maths in the terms

The terms give their own example: a deposit of 500 kr produces a 500 kr bonus, a total of 1 000 kr, and 1 000 kr times 30 means 30 000 kr of bets before you can cash out. The base is the deposit and the bonus together, not the bonus alone.

Translated to the euro version, a EUR 50 deposit with a EUR 50 bonus gives EUR 100, and 30 times that is EUR 3,000. The money in your account is played first, and the bonus becomes active only after all your real money has been wagered.

Three days to claim, 30 days to finish

Once a qualifying deposit is made, the bonus expires unless you claim it in the Bonus menu within 3 days. After claiming, you have 30 days to meet the wagering, otherwise it expires. For the 30 000 kr example that is 1 000 kr of bets per day.

The deposit and any winnings tied to a deposit bonus are locked until the wagering is done. If your bonus balance falls below 1 kr, the bonus is forfeited automatically. Only one bonus can be active at a time, and if several are active they are wagered one after another, starting with the first.

Live casino and table games count 0%

Slots count 100% towards wagering. Video poker counts 30%, live roulette 15% and live blackjack 10%. Table games, live casino in general, live baccarat, other games and every buy-feature game count 0%. Put differently, of a 40 kr bet, 12 kr counts on video poker, 6 kr on live roulette and 4 kr on live blackjack.

Two named lists adjust this. Some slots count only 50%, among them Blood Suckers, Dead or Alive, Mega Joker, Neon Staxx and Serengeti Kings. Others count 0%, such as Plinko Pop, Solar Queen, Take the Bank and Keno Party.

The 50 kr maximum bet

While wagering a bonus, the maximum is 50 kr per bet, or the equivalent in another currency. The limit includes double-up wagers after a round, such as putting winnings on red or black. At 50 kr a bet, 30 000 kr is at least 600 bets.

The terms also forbid delaying rounds, leaving large bets on the table, and using bonus money only to move through game stages, naming games such as Koi Princess, Blood Suckers and Tower Quest. The casino can revoke any bonus it judges was obtained by misuse of the system.

Free spins and free money: x35, x50 and a 1 000 kr cap

Free spins are valid for 48 hours unless stated otherwise. The wagering on them is the amount won times 35. No-deposit spins, and no-deposit free bonus money, have a withdrawal limit of 1 000 kr. The standard wagering for free bonus money is x50.

Spin offers are either tied to a deposit or awarded on login without one, and the terms say the specific promotion rules take priority over these general ones.

Few reviews, mixed scores

CasinoGuru gives FatBoss a Safety Index of 7.5, tier Above average, and calls its terms fair. It records 9 complaints: 4 resolved and 5 rejected. AskGamblers shows a CasinoRank of 6.6 and a player rating of 5.3, but from only 3 reviews. Trustpilot shows 2.2 stars from 36 reviews. None of the sources splits the complaints by topic, so we cannot say how many concern the bonus.

Who should take the FatBoss welcome bonus

It suits a slots player who deposits a small amount, wants a clear example of the wagering sum in the terms and can play 50 kr or less per bet. The 30x on deposit plus bonus is stated openly.

It does not suit live casino or table game players, bonus-buy players, or anyone from the excluded countries. Unused bonuses can also be removed after 3 months, so a bonus left alone is not a reserve.

Myths vs facts

Myth: The 30x applies to the bonus only.
Fact: The terms apply it to the bonus and the deposit together, so a 500 kr deposit and 500 kr bonus means 30 000 kr of bets.
Myth: Live blackjack is a good way to clear the bonus.
Fact: Live blackjack counts 10%, live roulette 15%, and live casino in general, table games and buy features count 0%.
Myth: Free spin winnings carry the same 30x.
Fact: The wagering on free spin winnings is x35, and free bonus money is x50, unless the promotion says otherwise.
