Cash chest
Adds a stated cash value to the bonus total. Check whether the value is shown in currency or stake units before comparing screenshots.
Mine Rush field guide
Mine Rush has a game feature called Treasure Hook Bonus and may also be played under an operator promotion. Those are different things. This page documents the 50-key route, Standard and Premium purchase costs, three lives and chest results without inventing reward odds.

Three entry routes
| Route | Cost or condition | Version | Evidence |
|---|---|---|---|
| Key collection | 50 credited keys | Regular Treasure Hook | Official mechanics and interface |
| Standard Buy | 50× selected stake | Regular chest pool | Official selection screen |
| Premium Buy | 100× selected stake | Upgraded chest pool | Official selection screen |

The key route requires time and ordinary round exposure. Paid entry removes the waiting period but creates a large single commitment. Neither should be called free. Keys can be earned during wagering, while a purchase charges many stake units at once.
Key accounting
VeliPlay stores progress separately for every combination of bet and difficulty. Suppose a player has 18 keys at €0.50 on Low. Moving to €1 on Low opens a different counter. Moving back to €0.50 Low should restore the earlier track. The same segmentation applies when only difficulty changes.
| Stake | Mode | Example saved keys | Same track? |
|---|---|---|---|
| €0.50 | Low | 18 | Reference track |
| €1.00 | Low | 4 | No, stake changed |
| €0.50 | Medium | 7 | No, mode changed |
| €0.50 | Low | 18 | Yes, original pair |
These key totals are an explanatory example, not claimed results. The table shows how the indexing logic works. If the current interface behaves differently, record the version and contact the operator before making further wagers.
Up to one key may appear on a step. The wording does not mean every step gives one, and it does not publish the chance. Do not calculate a “key return” by assuming a frequency the provider has not stated.
Inside Treasure Hook

The feature begins with three lives. Opening chests increases the displayed bonus total and can alter the remaining state. Provider media identifies cash, Extra Life, Multiplier and combined Extra Life plus Multiplier outcomes. The remaining lives and running total should be read after each reveal.
Adds a stated cash value to the bonus total. Check whether the value is shown in currency or stake units before comparing screenshots.
Applies the displayed factor under the game's feature rules. A multiplier icon alone does not reveal its probability or average contribution.
Adds survival within the bonus sequence. A life extends the feature; it is not a separate cash payment.

Cost table
| Selected stake | Standard 50× | Premium 100× | Difference |
|---|---|---|---|
| €0.10 | €5 | €10 | €5 |
| €0.20 | €10 | €20 | €10 |
| €0.50 | €25 | €50 | €25 |
| €1.00 | €50 | €100 | €50 |
| €2.00 | €100 | €200 | €100 |
Check multiplication before confirming. A 100× button at €2 commits €200 in one action. The label “Premium” describes the feature version, not the affordability of the purchase and not a known return advantage.
Compare the purchase with the entire session budget. If one click exceeds the preset boundary, the option does not fit the plan. Do not deposit more simply to make a feature button available.
Casino promotions
An operator welcome bonus, free-bet offer or cashback promotion is not the Treasure Hook Bonus. Operator terms can set wagering requirements, maximum qualifying stakes, game contribution rates, excluded features, withdrawal caps and expiry dates. A game feature may contribute at 0%, a reduced percentage or be prohibited during bonus play.
No universal Mine Rush promo code is verified in the provider evidence. We do not repeat codes from unrelated affiliate pages. Before opting in, save the dated terms and check that Mine Rush and Bonus Buy are explicitly permitted. If the title is absent from both the included and excluded lists, ask support in writing.
| Term | Question to ask | Why it matters |
|---|---|---|
| Wagering | Bonus only or deposit plus bonus? | Changes total required turnover |
| Contribution | What percentage does Mine Rush count? | A 10% rate makes clearance ten times slower |
| Maximum bet | Does the limit apply to GO or feature purchase? | Exceeding it can void bonus funds |
| Bonus Buy | Is direct feature entry allowed? | Many promotions exclude purchases |
| Expiry | Exact date, time and timezone? | Unfinished wagering can expire |
| Withdrawal cap | Is converted cash limited? | Affects the real value of the offer |
Value limits
They cannot provide the probability of cash, multiplier or extra-life chests. They cannot show the expected value of Standard or Premium. They cannot establish whether an operator has changed a configuration field, and they cannot prove that a future chest will resemble a captured one.
A sound bonus review must therefore stop at documented mechanics, price and interface state. If VeliPlay later publishes a paytable or feature probability document, the page can add those numbers with a source date. Until then, ranking Standard or Premium by expected return would be speculation.
Bonus due diligence
Ask whether the feature result is credited as withdrawable cash, bonus balance or another restricted field. The game can display a reward while operator terms still govern withdrawal, wagering and maximum payout. Save both the game result and account transaction entry if they appear different.
Ask whether a direct purchase is allowed while an operator promotion is active. Many casino terms restrict feature buys because they compress wagering into high-variance events. Violating a maximum-bet rule or excluded-game clause can void bonus funds even when the game interface allowed the click.
Ask whether the 50× or 100× price is calculated from total stake, base stake or another configured unit. Mine Rush provider media presents those factors against the selected bet. The current confirmation screen should show the money amount before purchase; cancel if the multiplication does not match.
Ask how an interrupted chest feature resumes. Record remaining lives, running total, account balance, time and round identifier before reloading. Do not open another purchase to test whether the first one returns. The operator server record should resolve the state.
Keys should be checked after changing one setting at a time. Start with stake, return to the original value, then test difficulty. This reveals separate counters without spreading a funded session across many tracks. A demo is preferable for mapping this behaviour.
Promotions can expire in a named timezone and may cap converted winnings. A headline percentage is incomplete without wagering base, contribution, maximum bet, expiry and withdrawal limit. If the terms do not identify Mine Rush, request a written answer instead of assuming another crash game's contribution applies.
Confirmation screen
Confirm selected stake, price multiplier, currency total and feature version before pressing the purchase control. Standard at 50× and Premium at 100× should change immediately when the stake changes. If the displayed currency amount does not match multiplication, cancel and ask support instead of relying on the feature name.
For a technical dispute, preserve the purchase round ID, opening balance, three-life state, each chest result, final feature total and closing balance. A single winning chest cannot show the net result, while a final total without the entry price cannot show cost. Do not confuse this record with a method for predicting the next chest.
Operator deposit promotions add another layer. Check whether a purchased feature counts toward wagering, violates a maximum-bet rule or receives zero contribution. The game screen cannot answer those account-specific terms.
Direct answers
Fifty keys on one stake-and-difficulty track open the regular Treasure Hook Bonus automatically.
Yes. Credited keys persist after TNT and between sessions according to VeliPlay, but totals remain separate for each bet and difficulty combination.
The Standard route costs 50 times the currently selected stake and opens the regular three-life chest bonus.
Premium costs 100 times the selected stake. It uses an upgraded chest pool presentation, but public reward probabilities are not disclosed.
Provider material shows cash rewards plus possible Extra Life, Multiplier or both. Exact occurrence rates are not published.
No public expected-value table proves that either route is more profitable. The purchase concentrates 50 or 100 ordinary stakes into one feature entry.
