THE QUICK ANSWER
A boost to a calculated reward does not mean that percentage of a deposit or all wagers is returned. Name the base before comparing the rate.
01
Ask what the percentage is applied to
A deposit benefit is described against an eligible top-up. A rakeback or reward boost changes a reward system calculated from activity. Gamdom's current help explicitly says its rewards depend on gameplay factors and are not a fixed percentage of total wagers.
This means a 15% reward boost, a 20% RakeBoost and a 20% deposit credit cannot be ranked simply by their headline numbers. Without each base and its conditions, a numeric comparison has no defined result.
Put the base beside the rate
Top-up credit
Percentage × eligible payment amount
Reward boost
Increase to a separately calculated eligible reward
Missing formula
A stand-alone rate cannot fill in undisclosed factors.
Generic bases explain the distinction; this does not reproduce a platform's full reward formula.

Compare the named mechanics
| Gamdom new-account boost | Current help describes 15% Boosted Instant Rewards for seven days after activation, with activation within six hours of registration. |
|---|---|
| Rainbet affiliate RakeBoost | Its Rewards Overview lists +20% for 72 hours after affiliate-code redemption. |
| Rainbet simultaneous boosts | The same source says boosts do not stack or queue; only the highest percentage applies at a time. |
| Top-up percentage | CaseHug's promo help describes an extra percentage of the eligible top-up amount, a different base from a calculated activity reward. |
| Unknown reward calculation | Do not replace undisclosed factors with an invented universal refund percentage or cash amount. |

A percentage needs a complete sentence
For a generic illustration only, 20% of a 100-unit payment is 20 units. A 20% increase to a separately calculated 10-unit reward adds two units. These invented bases illustrate why the words after the percentage matter; they are not reward quotes for any named account.
Record whether the source describes a percentage of the payment, a percentage of a reward, or a percentage used inside a formula. If the formula is undisclosed, state that limitation. No generic calculator can supply the missing factors.
A boost has eligibility and duration
Activation window
Check whether activation is available to that account.
Active period
Record the timer for the named reward boost.
Overlap
Rainbet documents highest-only boosts with no queue.
Reward record
The activity system determines what eligible reward exists.
No activity target, earning guarantee or recommendation to play is implied.

Duration and stacking can change the displayed offer
Read activation eligibility, expiry and overlapping-boost handling as separate conditions. A duration attached to a boost does not guarantee that an amount will be generated during that time. An activity reward still depends on its own criteria.
Use the currently active reward record to understand existing account activity. Do not treat the comparison as a target amount of play, a reason to generate activity or a method to recover losses. It supplies no expected return and does not claim that a larger advertised boost is more valuable.
05
Describe the offer without a stand-alone percentage
- Write the reward name and the base it changes.
- Record the activation window and duration.
- Check the documented overlap or stacking rule.
- Use the account's eligible reward record and ask about undisclosed or conflicting terms; do not invent a cash equivalent.
BEFORE YOU CONTINUE
Quick checklist
- Name the base after every percentage.
- Separate deposit credit from activity-generated rewards.
- Check activation, duration and overlap.
- Keep undisclosed calculations unknown.
