Four campaigns sit in the independent database and every one of them is missing the same number.
Seventy percent up to C$1,500 with 70 spins. Then 100% up to C$1,000 with 50. Also 120% up to C$1,000 with 60, and 110% up to C$1,500 with 100. Four offers, four caps, four spin counts — and no wagering multiplier attached to any of them, in any source we examined.
That gap is the whole page, because a percentage without a multiplier is a headline rather than an offer. Below we cover what the campaigns are, what the one flagged clause does, why we would decline the lot, and what the two published player accounts actually say.
| Campaign | Match | Cap | Free Spins |
|---|---|---|---|
| 🎁 Highest cap | 70% | C$1,500 | 70 |
| 🎰 Spin-weighted | 110% | C$1,500 | 100 |
| 💠 Highest match | 120% | C$1,000 | 60 |
| 🎯 Standard | 100% | C$1,000 | 50 |
Two observations before the criticism, because both are genuine.
These caps are real rather than aggregated. Compare against the series: Roby advertises 250% by summing three deposits, PowerUp advertises C$4,500 by summing several more, and both figures describe arithmetic rather than an offer you receive. Gravira's C$1,500 appears to be C$1,500 on a deposit, which is the honest way to present a match and worth crediting.
Percentages are also modest. Seventy to 120% is unremarkable in a segment where 250% headlines are standard, and unremarkable is a compliment here — inflated percentages exist to distract from the terms underneath them.
Now the problem. No source publishes a wagering requirement for any of those four campaigns. Not the independent audit, which logs the offers by headline and stops. Affiliate pages carry nothing either, and neither does the operator's own material as far as any reviewer has reproduced it.
Consider what that absence hides. On a C$100 deposit taking the 120% match, you hold C$120 of bonus credit. At 20× that is C$2,400 of turnover. Raise it to 35× and the figure reaches C$4,200; 40× puts it at C$4,800. Apply the multiplier to deposit-plus-bonus instead of bonus alone and every figure roughly doubles. Those are four completely different products wearing one number, and the number that separates them is not published.
One player supplies the only public statement on the subject, and it is not a figure: he says the wagering follows standard rules and that you can withdraw your money as soon as you meet the requirements. Another reports getting the welcome bonus right away after depositing, with no weird activation steps or hidden requirements. Both accounts are positive. Neither contains a number.
Our position across this series has been consistent: a promotion whose cost is unpublished cannot be evaluated, and the live cashier panel is the only place the figure may surface. Where it does not appear there either, decline.
Take the 120% campaign and fund C$100:
Five blanks and one red flag against two solid lines. That ratio is the honest summary of this offer.
Independent review found exactly two unfair provisions in this venue's entire terms document. One governs verification and sits on our payments page. The other lives here:
Detection of certain betting techniques while wagering bonuses may result in confiscated winnings.
Read what that permits. The techniques are undefined. Detection rests with the operator. Your winnings are the consequence. And the trigger applies only while a bonus is active — meaning it cannot touch a player who never accepted one.
We have watched this exact clause work at two other brands in this series, which is the useful thing about auditing six venues rather than one:
| Venue | Same Clause? | What Happened |
|---|---|---|
| Jokersino | Yes | A player describes his $1,500 withdrawal cancelled for breaching the terms "by playing slots" — naming a title he says he never opened · three of four complaints unresolved, two of them confiscations |
| Cherry Spins | Yes, among seven flagged clauses | Two confiscation complaints on file · eleven disputes, zero resolutions · no reachable support |
| Gravira | Yes, one of only two flagged | Nothing yet — zero complaints, at a casino established in 2025 |
That third row is the honest assessment of this brand's promotional layer. The mechanism is loaded. Nobody has reported it firing. A venue eighteen months old with an empty archive tells you the trigger has not been pulled, not that it will not be.
Decline the bonus.
Reasoning is arithmetic rather than suspicion. You would be accepting an unpublished turnover requirement, an unpublished window, an unpublished stake ceiling, and an unpublished win cap — in exchange for C$120 of credit — while activating the only clause at this venue that has produced confiscated payouts elsewhere. Playing without a bonus removes all six unknowns at once and costs you a modest match you cannot price anyway.
Should you take one regardless, take the smallest. The 100% up to C$1,000 campaign on a C$50 deposit gives you C$50 of credit and 50 spins, which is a cheap way to find out what the terms panel actually says once you are inside.
Documentation here is thin and comes from a single source.
A player review describes the bonus programme as constantly updated, with regular tournaments carrying prizes and quests paying free spins and bonus cash. He calls the whole structure fire, which is an assessment rather than a specification. Affiliate coverage adds nothing.
The independent audit records four welcome campaigns and no ongoing promotional structure whatsoever — no reload calendar, no cashback tier, no tournament schedule.
Compare against the series. Roby publishes 15% daily cashback at 1× wagering and itemised weekend reloads. PowerUp publishes 25% live cashback at 1× and a hundred-tier progression. LuckyHills publishes Wednesday spins, Sunday reloads, and 10% weekly cashback at 5×. Every one of those figures is checkable. Gravira's tournaments exist on one player's word.
We are not going to describe a promotional calendar nobody publishes. What we can say is that no cashback appears in any source for this brand — and cashback has been the single best-value offer at three of the five venues we audited before it.
Affiliate pages describe a VIP structure spanning twenty levels. The independent audit records nothing — no tiers, no thresholds, no benefits, no qualification criteria.
Those same affiliate pages claim 4,900 games and 120 providers against an audited 37, and one claims the venue launched in 2020 against an audited 2025. A source wrong about the founding year and wrong about the catalogue by a factor of three is not a source we would take a VIP schedule from.
Our position: a twenty-level ladder may exist. Nothing verifiable describes it, and at a casino this new, tier benefits are a promise about a future that has not happened yet.
Credit first, because the overall result is better than most of this series. Independent review of the whole terms document found two issues. Cherry Spins carried seven. Jokersino carried three. SlotShake carried two. Two is at the good end.

Connecting the layers, as we have on every brand in this series.
Good news first, and it is real. Ceilings sit at €2,000 daily, €7,500 weekly, and €15,000 monthly — and the independent audit raises no low-limit flag, the only brand across our six audits to avoid one. Clear an unpublished rollover, convert a €5,000 balance, and it collects in three days rather than three months. That is a functioning exit, which is more than Jokersino at €2,000 weekly can say.
Bad news is the shape of the risk. At other venues the danger was the ceiling — money that could not leave fast enough. Here the ceiling works and the danger sits earlier in the chain: an unpublished multiplier you cannot plan around, and a clause permitting the operator to decide your betting technique was the wrong kind before you ever reach the cashier.
Which reframes the recommendation. At brands with punishing ceilings, we said take the cashback and skip the match. Gravira has no cashback and a workable ceiling — so the advice is simpler: play with your own money, at limits you set yourself using the deposit and stake tools this venue actually provides, and let the cashier do the one thing it appears built to do.
Three things here are better than the series average. Caps look real rather than aggregated. Percentages are modest rather than inflated. And the terms document as a whole drew only two flags, which is the second-cleanest result across six audits.
What we cannot do is recommend any of it, and the reason is not suspicion — it is that six parameters are missing. No multiplier, no window, no stake ceiling, no win cap, no contribution table, no cancellation policy. Every one of those decides whether C$120 of credit becomes C$120 of money, and not one is published anywhere a reader can find.
Sitting alongside those blanks is the one clause that has produced real confiscations elsewhere in this series — undefined betting techniques, detected by the operator, forfeiting your winnings, active only while a bonus runs. Gravira has no complaints and a good support record, so nothing suggests it will be used aggressively. It also has no history at all, so nothing suggests it will not.
Guidance is one line. Decline the bonus, use the deposit and stake limits instead, and let a venue with a workable ceiling and a clean archive prove itself on your own money rather than on credit you cannot price.
Four campaigns appear in the independent database, all in Canadian dollars: 70% up to C$1,500 with 70 spins, 100% up to C$1,000 with 50, 120% up to C$1,000 with 60, and 110% up to C$1,500 with 100. Which one reaches you depends on the campaign live when you register.
Not published — by the audit, by affiliate coverage, or by anything else we examined. That absence is the single most important fact on this page, since a multiplier between 20× and 40× on bonus-only versus deposit-plus-bonus describes four different products under one headline.
Also unpublished. So are the maximum stake during rollover, the bonus win cap, the game contribution table, and the cancellation policy. Six parameters, all blank.
One clause permits it: detection of certain betting techniques during bonus wagering may result in confiscated winnings. The techniques are undefined and the judgement is the operator's. It applies only while a bonus is active — which is why declining the bonus removes the risk entirely.
No. The complaint archive is empty and no player has described anything of the sort. Read that against the venue's age, though — it launched in 2025. The same clause at Jokersino produced a cancelled $1,500 payout, and at Cherry Spins it sits among seven flagged terms with two confiscation disputes on file.
None appear in any source. That is worth noting, because cashback at 1× or 5× wagering has been the best-value offer at three of the five brands we audited before this one. Gravira publishes no cashback tier at all.
One player describes regular tournaments with prizes and quests paying free spins and bonus cash, calling the programme constantly updated. No schedule, prize pool, or mechanic appears in any verifiable source.
Affiliate pages claim twenty levels. The independent audit records nothing about it. Those same pages claim 4,900 games against an audited 37 studios and a 2020 launch against an audited 2025, so we would not build expectations on them.
None documented for this venue.
No. You would accept six unpublished parameters and activate the one clause at this venue capable of costing you a payout, in exchange for a match you cannot price. Use the deposit and stake limits this brand actually provides and play with your own money instead.
