Bonus terms compared
Bonus terms at Duelbits alternatives: wagering, max bet and expiry
Ten sets of bonus terms we read on 2 September 2026 put wagering between 30× and 50×, and nine of the ten cap the bet at €5 or 5 USDT while it runs. Here is each document's multiple, maximum bet and expiry, with the clause behind it.
Duelbits players who have taken a promotion know that the terms, not the headline, decide what can be withdrawn. Across ten sets of bonus terms from other casinos, read on 2 September 2026, wagering runs from 30× to 50× the bonus. Duelbits' own promotions and their published terms are on Duelbits promotions; this page compares the alternatives.
The three numbers that decide a bonus
A welcome offer is sold as a percentage and a cap. Neither decides whether you can cash out. Three other numbers do: the wagering multiple, the largest bet allowed while wagering runs, and how long the bonus lives. All three sit in a separate document that most players open only after a balance has gone.
Of the three, the maximum bet ends the most bonuses, and it does so quietly. One larger spin placed out of habit can void the balance under the same document that granted it.
Ten documents side by side
Source: each operator's bonus terms, read 2 September 2026. A numbered clause is cited by number; an unnumbered one by the heading it sits under. A dash means the document gives no figure. We opened an eleventh set, CryptoLeo's, and could not read it.
| Operator | Wagering | Max bet while wagering | Expiry | Clause or heading |
|---|---|---|---|---|
| BitStarz | 40× the bonus | €5 (and per-coin equivalents) | 7 days for the welcome package, 24 hours for everything else | 3.4, 3.10, 3.7 |
| Oshi Casino | 40× | €5 | 5 days | Deposit-bonus and general-bonus headings |
| PlayAmo | 50× | €5 | — | 1i, 1d, 7c |
| BitDreams | — | €5 | 30 days | General bonus terms, unnumbered |
| 7BitCasino | 35× | 60 μBTC; 12 μBTC on the welcome package | 14 days | Welcome package and general terms, unnumbered |
| Bitkingz | 45× | €5 | one month | 2.1.1 |
| Mirax Casino | 30×; 15× on VIP chips and cashback | €5; €1 on welcome package bonuses | 14 days | General bonus T&C, first deposit bonus |
| Slotum | 50× | €5 | — | 2.1, 2.2, 1.11 |
| Metaspins | — | 5 USDT | — | 14.11, 14.18.2 |
| Bets.io | 40× | 5 USDT; 2 USDT on the welcome deposit bonuses | 7 days | First deposit bonus item 5, general terms items 5 and 12 |
The dashes in the expiry column need reading as written. PlayAmo's clause 7c says what happens when a bonus expires and gives no number of days. Slotum's clause 1.11 says every bonus has a duration and names none site-wide. Metaspins' clause 14.18.2 describes forfeiture without a period. None of those is a zero-day expiry or an unlimited one; each describes a rule and leaves it unbounded.
Wagering multiples: a narrow band
Eight of the documents print a multiple, and all eight fall between 30 and 50:
- 30× Mirax (15× on VIP chips and cashback)
- 35× 7BitCasino
- 40× BitStarz, Oshi Casino, Bets.io
- 45× Bitkingz
- 50× PlayAmo, Slotum
BitDreams and Metaspins print no multiple for standard bonuses. The spread is real but narrow. On a 100-unit bonus, the gap between the lowest and the highest multiple is 3,000 units of wagering against 5,000.
Maximum bet: €5 almost everywhere
Nine of the ten cap the bet at five euros or 5 USDT while wagering runs. The tenth, 7BitCasino, states the cap in micro-bitcoin, 60 μBTC generally and 12 μBTC on welcome package bonuses. That is the same kind of rule in a unit you have to convert before you can compare it.
Several documents go tighter than the headline figure. Mirax prints €5 in general and €1 on welcome package bonuses. Bets.io prints 5 USDT in general and 2 USDT on its welcome deposit bonuses. Bitkingz and Slotum both say the cap includes double-up wagers made after a round has finished and bonus rounds bought inside a game. Both are ways to go over the limit without ever changing your stake.
What happens when the cap is broken
The documents differ in tone and agree in effect. Slotum's clause 2.2 is the plainest: breaking the maximum-bet rule means all winnings from the bonus are confiscated and the deposit refunded. BitStarz's clause 3.15 reserves the right to revoke a promotion and withhold the proceeds where the operator, in its sole discretion, deems the activity abusive.
These clauses sit in plain view in the bonus document, which is why it pays to read that document before the deposit rather than after.
Caps on what a bonus can pay
A fourth number appears in six of the ten, and it is the one that turns a large win into a small one.
- BitStarz caps winnings from a no-deposit bonus or free spins at €100, and prints no cap for deposit bonuses (1.1).
- Oshi Casino prints €5,000 under its deposit-bonus headings.
- PlayAmo caps a no-deposit bonus at €50 (1a).
- Bitkingz caps a no-deposit bonus at €50 for players who have not deposited, and at ten times the bonus for those who have.
- Slotum caps no-deposit bonuses and no-deposit free spins at €50 (1.7).
- Bets.io caps deposit-bonus winnings at 5,000 USDT and at five times the qualifying deposit (general terms item 8).
We list these caps because they are the figures most often quoted out of context.
Headlines we have not matched to terms
Some of the biggest numbers in the market sit on front pages whose bonus terms are outside the ten above. TrustDice's front page leads with 500% up to $90,000 plus 100 free spins. We have not read the wagering terms behind that banner, so we print no multiple for it.
Bitcasino.io's front page offers up to 5,000 USDT on the first three deposits, and its promotions page, read on 2 September 2026, sets 30× on bonus money. Its full bonus terms sit outside the ten documents above, so it has no row in the table.
Vave's package, and what its page leaves out
Vave is our advertiser and the only paid placement on this site. Its promotions page, read on 24 August 2026, offers four deposits: 150% up to 1.5 BTC with 100 free spins, then 100% up to 1 BTC, 50% up to 1 BTC and 25% up to 0.5 BTC. That page states no wagering multiple, so we print none. Read Vave's bonus terms before you accept it, the same as anywhere else.
Its VIP scheme, by contrast, prints its arithmetic: one point per 30 USDT wagered on slots, and 200 points redeem for 1 USDT.
What to check before you accept any bonus
- The multiple, and what it multiplies. BitStarz states its 40× against the bonus; check what each document applies its multiple to.
- The maximum bet, including the lower welcome-offer figures and whether bought bonus rounds count.
- The expiry, in days. If the document gives none, assume you will not know until it happens.
- The win cap, especially on free spins.
The same habit applies to payouts: a balance still under bonus terms may face different withdrawal rules, which we compare on withdrawal limits compared. For the operators themselves, product by product, start with our Duelbits alternative picks, or go straight to the best Duelbits alternatives.
