Boom bonus: what you're agreeing to before you claim
Knowing when a bonus works against you
Before getting into what Boom puts on the table, it is worth spending a moment on the mechanics that quietly shrink a win — or wipe one out entirely. Understanding the conditions that void a bonus is the most useful thing a player can do before opting in, and it is where we start.
Boom's terms identify several routes to a cancelled bonus. Deliberately delaying the completion of a game round or a bonus feature until after your wagering requirement is met — or until after a new deposit lands — is treated as manipulation and gives the operator the right to void the associated winnings. The same applies to playing out a slot's progression mechanic in a way that exploits active bonus conditions: a practice the terms call out by name.
More broadly, the operator lists a cluster of behaviours under "bonus abuse": holding real-money funds while avoiding wagering them (cash stashing), accumulating bonuses without working through them (bonus stashing), or depositing only to pick up free spins and then withdrawing your real balance before meeting the 1× deposit turnover requirement. Any of these can result in winnings being confiscated and accounts being closed.
Worth remembering: the 1× deposit wagering rule applies before any cash-out — not just before the bonus clears. Make sure your deposited amount has been turned over at least once before requesting a withdrawal, even if you are not using a bonus.
Some games are excluded from bonus play entirely: Blood Suckers, Dead or Alive, The Wish Master, all Spribe titles (including Mines, Plinko and Dice), Hacksaw Gaming's Coins, Boxes and Mines, and 100 Bit Dice contribute 0% toward any wagering requirement. Staking on these while a bonus is active does not count toward clearance — and placing large bets on them when the maximum bet rule is in force can cause the operator to remove associated winnings.
Boom's welcome offer in plain numbers
Boom's standard welcome offer is a 100% deposit match up to €100, paired with up to 100 Free Spins. T&Cs apply. 18+. New customers only. Please gamble responsibly (BeGambleAware.org).
Both parts of the offer carry a wagering requirement. The bonus amount must be wagered 40 times before any withdrawal. Winnings from the free spins carry the same 40× requirement applied to the winning sum. Bonus money that goes unused is removed after 30 days. The cap on winnings you can withdraw from any free bonus is €500 — amounts above that are forfeited.
| Term | Detail |
|---|---|
| Deposit match | 100% up to €100 |
| Free spins | Up to 100 |
| Wagering requirement | 40× the bonus amount |
| Free spins winnings wagering | 40× the winning sum |
| Maximum bet while wagering | €5 per round |
| Bonus expiry | 30 days from award |
| Maximum withdrawal from free bonus | €500 |
Eligibility depends on the operator's own terms and on where you are located — not every offer is available in every market. Check the terms on the platform before depositing.
Clearing the wagering requirement
A 40× requirement on a €100 bonus means turning over €4,000 before a withdrawal becomes available. Slot machines contribute 100% toward that figure, making them the most efficient route through. Table games and live dealer titles contribute far less: roulette of any kind counts for 5%, and blackjack variants contribute a maximum of 10%.
The maximum bet while a bonus is active is €5 per round. Placing larger bets is not blocked, but any winnings from a stake above that limit may be removed at the operator's discretion. Sticking to €5 per spin or below is the safest way to protect a clearing run.
- Slots: 100% contribution
- Video poker: up to 30%
- Blackjack (all variants): maximum 10%
- Live dealer games: 10%
- Roulette (all variants): maximum 5%
- Baccarat and Punto Banco: 5%
If the offer genuinely does not suit your playing style — particularly if you favour table games or live titles — declining it and depositing without a bonus is a reasonable choice. Playing through your own money carries none of these constraints.
Boom's loyalty scheme and ongoing rewards
Beyond the welcome offer, Boom runs a continuous loyalty mechanic called Boom Cash. Every eligible bet feeds 0.3% of the stake into a visible pot — split as 0.2% toward the current pot and 0.1% toward the next. After every 1,000 bets the pot resets, and the accumulated Boom Cash becomes claimable as bonus money carrying a 20× wagering requirement.
The maximum addition per bet to the pot is €1, so very large individual bets are capped in what they contribute. Most game types count at 100%, with the same exceptions as the welcome offer: baccarat and Punto Banco contribute nothing, and the excluded titles listed above feed 0% in all circumstances.
The operator also runs an invitation-only VIP programme for high-activity players, with personalised bonuses, faster withdrawals, and dedicated support — access is at the operator's discretion and is not applied for directly.
One practical note on account management: an account that goes unused for three months while holding a real-money balance is flagged as "paused", at which point a monthly inactivity fee may apply. Logging in periodically keeps the account active and the balance intact.
Responsible gambling
Promotions add value, but they also add conditions. If a bonus ever makes you feel you need to chase a target or play beyond what you intended, set it aside. Boom offers deposit limits, loss limits and wagering limits across 24-hour, weekly and monthly timeframes, plus time-out options and self-exclusion. Use them early, not as a last resort.

Frequently asked questions
Does the Boom welcome bonus require a minimum deposit to activate?
The welcome offer is a 100% match up to €100 plus up to 100 free spins. The minimum deposit amount required to trigger it is not published by the operator, so check the current terms on the platform before depositing.
What is the maximum bet allowed while working through the wagering requirement?
While a bonus is active, the maximum permitted bet is €5 per round. Winnings resulting from a higher stake may be removed by the operator, so staying at or below that limit throughout the clearing process is important.
How long does bonus money stay in my account before it expires?
Bonus money is valid for 30 days from the date it is awarded. Any unused bonus balance is removed when that window closes, unless a specific campaign states a shorter expiry period.
Is there a cap on what I can withdraw from free spins winnings?
Yes. Winnings earned from a free bonus can only be withdrawn up to a maximum of €500. Any amount above that threshold is forfeited, and the 40× wagering requirement must be met before a withdrawal can be made.
