Mostbet offers new customers a multi-stage welcome promotion called Start of a Dream, extending rewards across the first five qualifying deposits instead of limiting the offer to the initial payment. Depending on the selected option, customers can receive sports or casino bonus funds alongside free spins or free bets, with the first-deposit reward reaching 125% when the payment is made within 30 minutes of registration and later deposits unlocking their own percentage-based rewards.
How the Mostbet Welcome Bonus Series Works
Start of a Dream is structured as a sequence rather than a single registration reward. Customers can unlock bonuses as they progress through their first five qualifying deposits.
The offer is available only for accounts using EUR. Customers must register and log in to Mostbet, select either the sports or casino bonus, and make a qualifying single deposit. Deposits made through MOSTBET Cash are excluded.
There is an important choice at the beginning. Selecting the sports bonus means giving up the casino alternative, and selecting the casino option means giving up the sports alternative. The decision cannot be changed after the deposit has been made.
For deposits two through five, the required reward must be selected on the Bonuses page after making the corresponding deposit. Bonus funds and free spins can take up to 72 hours after the promotional deposit to appear on the bonus balance.
First Deposit: Up to 125% and 250 Free Spins
The first deposit has two percentage levels depending on how quickly a new customer funds the account.
An increased 125% bonus is available when the first deposit is completed within 30 minutes after registration. Waiting longer does not necessarily remove the first-deposit offer: a 100% standard bonus remains available when the qualifying first deposit is made within seven days.
The maximum bonus amount is €400.
For the version without additional free spins, the minimum qualifying deposit is €10. A version that includes 250 free spins requires a minimum deposit of €20.
First Deposit Calculation
Suppose a customer deposits €200 within 30 minutes of creating the account.
The increased bonus calculation is:
€200 × 125% = €250
A qualifying €200 deposit can therefore produce €250 in bonus funds.
If the same €200 qualifying first deposit is made later but still within seven days of registration, the standard rate becomes:
€200 × 100% = €200
Timing alone creates a €50 difference in this example.
The maximum remains €400, so increasing a deposit indefinitely does not continue increasing the bonus once the cap has been reached.
Second Deposit: 50% Plus Crash Game Free Bets
The second-deposit stage changes the structure. Both the casino and sports options provide a 50% deposit bonus, with the maximum bonus capped at €650.
Additional crash-game free bets depend on the qualifying deposit level and selected bonus type.
| Minimum Deposit | Casino Reward | Sports Reward |
|---|---|---|
| €30 | 50% + 10 free bets | 50% + 10 free bets |
| €60 | 50% + 20 free bets | 50% + 15 free bets |
| €90 | 50% + 30 free bets | 50% + 20 free bets* |
The official rules list progressively larger free-bet packages at the €30, €60 and €90 thresholds.
*The supplied rules contain inconsistent wording in the final sports example: the condition states 20 free bets, while its example later mentions 15. The advertised condition has therefore been retained here rather than silently changing the source.
Second Deposit Example
Consider a €100 second deposit.
At a 50% match:
€100 × 50% = €50
The customer receives €50 in bonus funds, subject to the applicable conditions.
Because €100 also clears the €90 threshold, it can qualify for the highest listed additional free-bet tier for this deposit stage.
Third Deposit: A Full 100% Match
The third deposit increases the percentage again.
Both sports and casino customers can receive a 100% bonus, capped at €650. The accompanying free-spin package depends on the deposit threshold.
| Minimum Deposit | Deposit Bonus | Extra Reward |
|---|---|---|
| €30 | 100% | 15 free spins |
| €60 | 100% | 30 free spins |
| €90 | 100% | 50 free spins |
For example, a €150 qualifying third deposit would generate:
€150 × 100% = €150 bonus
The percentage does not change between these three thresholds. Instead, a larger qualifying deposit unlocks more free spins. The €60 and €90 tiers and their corresponding rewards are specified separately in the promotion rules.
Fourth Deposit: Sports and Casino Rewards Diverge
The fourth deposit creates one of the biggest differences between the two bonus paths.
The casino reward provides 100%, while the sports version increases to 150%. Both have a maximum bonus of €650.
The available reward levels are:
| Minimum Deposit | Casino | Sports |
|---|---|---|
| €30 | 100% + 15 free bets | 150% + 20 free bets |
| €60 | 100% + 25 free bets | 150% + 30 free bets |
| €90 | 100% + 40 free bets | 150% + 40 free bets |
The additional rewards are free bets for a crash game. Higher qualifying deposits unlock progressively larger packages.
Comparing a €100 Fourth Deposit
A casino customer making a qualifying €100 deposit would have:
€100 × 100% = €100 bonus
Under the sports option:
€100 × 150% = €150 bonus
Both deposits exceed the €90 threshold, meaning the relevant additional package contains 40 crash-game free bets.
This stage therefore produces a substantial difference between sports and casino bonus funds despite using the same deposit amount.
Fifth Deposit: The Final Welcome Reward
The fifth deposit completes the promotional sequence.
This time, the percentage advantage switches toward the casino offer:
Casino: 125% + 100 free spins
Sports: 75% + 100 free spins
The minimum qualifying deposit is €30, while the maximum bonus is €650.
With a €200 deposit, the calculations would be:
Casino: €200 × 125% = €250
Sports: €200 × 75% = €150
Both versions additionally include 100 free spins under the supplied conditions.
Mostbet Welcome Bonuses at a Glance
The percentage structure changes considerably throughout the five-deposit sequence.
| Deposit | Casino Bonus | Sports Bonus | Maximum Bonus |
|---|---|---|---|
| 1st | Up to 125% | Up to 125% | €400 |
| 2nd | 50% | 50% | €650 |
| 3rd | 100% | 100% | €650 |
| 4th | 100% | 150% | €650 |
| 5th | 125% | 75% | €650 |
Additional free spins or crash-game free bets can accompany these percentage rewards depending on the deposit and qualifying tier.
This progression is why the promotion should not be evaluated only by its first-deposit headline. Each stage has its own percentage, deposit threshold and possible extra reward.
Sports Bonus Wagering Explained
Sports bonus funds do not immediately become withdrawable real funds.
Mostbet requires customers to complete wagering equal to 5x the sports bonus within 30 days after the first deposit.
Qualifying wagers must be accumulators containing at least three events, and each event must have odds of 1.40 or higher. The rules do not set a maximum number of selections.
Suppose a customer receives a €150 sports bonus.
The required wagering is:
€150 × 5 = €750
The customer therefore needs €750 in qualifying accumulator stakes under the promotion rules.
Receiving €300 in sports bonus funds would raise that requirement to:
€300 × 5 = €1,500
Bets that fail to satisfy the applicable wagering conditions do not contribute toward completing the requirement.
Casino Bonus Wagering Explained
Casino bonus conditions are considerably different.
Casino bonus funds carry a 60x wagering requirement, which must be completed within 72 hours after the first deposit according to the supplied rules. Eligible activity can take place in Casino, Live Casino and Virtual Sports, although not every wager necessarily contributes at its full value.
For example, a €100 casino bonus creates a nominal wagering requirement of:
€100 × 60 = €6,000
A €250 casino bonus would produce:
€250 × 60 = €15,000
The contribution rate is particularly important. The rules state, for example, that only 10% of a wager is counted in Live Casino and Virtual Sports.
Customers should therefore check eligible games and their contribution rates instead of calculating the requirement solely from total stakes.
How Free Spin Winnings Are Wagered
Winnings generated from promotional free spins are transferred to a separate casino bonus balance.
Those bonus funds also carry a 60x wagering requirement, with 72 hours available after the corresponding bonus account is created.
This means receiving 250 free spins with the first deposit should not be interpreted as receiving unrestricted cash of an equivalent value.
The spins are the initial promotional reward, while any resulting bonus winnings must pass through the applicable wagering process before conversion into real funds.
What Happens When Real and Bonus Funds Coexist?
Mostbet prioritizes the real-money balance.
When an account contains both real and bonus funds, wagers are first taken from the real balance. Bonus funds begin to be used only after the real balance reaches zero.
After all wagering requirements have been successfully completed, the remaining eligible bonus is transferred to the main account. The converted amount cannot exceed the original bonus value.
This is an important distinction when calculating the practical value of a welcome reward: the displayed bonus amount is not automatically equivalent to immediately withdrawable cash.
Withdrawal Rules During an Active Bonus
Withdrawals require particular attention while a bonus account remains active.
The rules allow withdrawals within specified limits connected to deposited and wagered funds, provided that more than twice the bonus value remains on the gaming balance. A withdrawal that violates the stated requirement can be treated as withdrawal from the promotion, resulting in the bonus balance being canceled.
Because the five-deposit promotion can involve several rewards, customers should check their active bonus status before requesting a withdrawal.
Deadlines Matter
Sports and casino rewards operate under very different time limits.
Sports wagering must be completed within the applicable 30-day period, while casino wagering is subject to a much shorter 72-hour window. Bets also need to settle before the relevant bonus validity period expires.
The first deposit has an additional timing consideration of its own: depositing within 30 minutes after registration unlocks the increased 125% rate, whereas the standard 100% first-deposit rate is available for a qualifying payment made within seven days.
Customers therefore need to consider both the claiming deadline and the subsequent wagering deadline.
Choosing Between the Sports and Casino Welcome Offers
The two bonus routes share several percentage rates, but they are not interchangeable.
Sports customers face a lower 5x wagering multiplier but must complete it through qualifying accumulators with at least three selections priced at 1.40 or higher.
Casino customers face a much higher 60x requirement, and individual game categories can contribute at different rates.
The fourth and fifth deposits also highlight how reward percentages diverge. Sports customers receive 150% on the fourth deposit compared with 100% for casino, while the fifth deposit gives casino customers 125% compared with 75% for sports.
Most importantly, the initial choice matters because customers cannot claim both versions of the welcome offer. Once one bonus path has been selected and the deposit completed, the alternative cannot simply be substituted later.
