MelBet matches a Monday deposit 100%, up to 100 USD, but only for deposits made inside that single day — and only when a different, deposit-count-based promotion isn't already claiming that same deposit instead. It's one of the site's tighter offers to actually clear, with a 24-hour wagering window and an accumulator rule that's stricter than it first looks, both of which matter more here than they would on a bonus with a week or a month to work with.
The Monday Window and What You Get
The offer runs only from 00:00 to 23:59 on Monday, and the match is a flat 100% of the deposit, capped at 100 USD, with a 5 USD minimum deposit to trigger it. Because the rate never changes with deposit size, the bonus tracks the deposit dollar-for-dollar right up to the cap: a 20 USD deposit returns a 20 USD bonus, a 60 USD deposit returns 60 USD, and an 80 USD deposit returns 80 USD, still comfortably under the ceiling. Once the deposit reaches 100 USD or more, the match flattens out — a 150 USD deposit would calculate to 150 USD at the 100% rate, but the bonus is capped at 100 USD regardless, and a 300 USD deposit produces exactly the same 100 USD bonus as the 150 USD one did. Getting it credited also depends on account setup being complete beforehand — full name, activated phone number, email, and country of residence on file, plus opting into bonus offers under Account Settings → Bonuses → Sport ahead of the deposit itself, since MelBet checks these conditions at the moment the deposit lands rather than after the fact.
Every Leg Has to Clear 1.65 — Not Just Some
The wagering requirement is 6 times the bonus amount, and it has to be cleared within 24 hours of the bonus landing or it's voided outright. Scaled against the deposit examples above, a 20 USD bonus carries a 120 USD wagering target, a 60 USD bonus carries 360 USD, an 80 USD bonus carries 480 USD, and the capped 100 USD bonus carries the maximum possible 600 USD target — all of it due inside the same single day regardless of how large the underlying deposit was. What sets this offer apart from several of MelBet's other accumulator-based promotions is the odds rule: every single selection in a qualifying accumulator needs to be priced at 1.65 or higher, not just three of them. Some of MelBet's other bonuses only require a handful of legs to clear a minimum odds floor while allowing the rest to sit lower — this one doesn't leave that room, so a long accumulator with even one selection below 1.65 doesn't qualify at all, no matter how high the other legs are priced.
To put a real slip against that rule: a three-selection accumulator priced at 1.70, 1.85, and 2.10 qualifies outright, since every leg clears 1.65. Swap the 1.70 leg for one priced at 1.55, though, and the whole accumulator falls out of contention for this offer's wagering requirement, even though the combined odds of the bet might still look attractive and the other two legs are both comfortably above the floor. That's the practical effect of an "every selection" rule versus the "at least three selections" wording MelBet uses elsewhere — it removes the option of padding an accumulator with a couple of shorter-priced, safer legs alongside the higher-odds ones.
Each accumulator still needs at least 3 selections, with both the start and settlement dates of every event falling inside the offer's validity window, and progress only counts once a bet is fully settled rather than the moment it's placed — a bet still pending when the 24-hour window closes doesn't contribute to the total even if it eventually wins. Handicap and Total-type bets don't contribute to the requirement regardless of their odds, and a refunded selection inside an otherwise-qualifying accumulator is simply dropped from the count rather than voiding the whole bet, so a four-selection accumulator with one refund is re-evaluated as three and can still qualify if the remaining legs meet the 1.65 floor.
When Royal Monday Doesn't Apply
A few conditions can keep this specific offer from landing even on a qualifying Monday deposit. If that deposit happens to be the account's second, third, or fourth deposit overall, MelBet's separate "Deposit Series" promotion takes precedence over Royal Monday for that same deposit — a detail worth knowing if the plan was specifically to claim this offer rather than the other one, since the two can't both apply to a single deposit. Making a withdrawal before that Monday's deposit also blocks the bonus from being credited entirely, and the offer is restricted to active customers making daily transactions on their account, so a mostly-dormant account depositing once on a Monday isn't guaranteed to qualify even with everything else in order. Only one Royal Monday bonus is available per customer regardless of how many Mondays pass, and it's limited to one per family, address, shared computer, and shared IP as well — a household with several MelBet accounts doesn't multiply the offer across them.
