Gravira is a 2025 Curaçao-licensed casino for Canada with about 6,000 games, Interac in both directions and a four-deposit welcome worth up to C$5,000 and 330 spins. The first-stage wagering of 35x on the bonus is lighter than most. Five days to finish it is not.
The short version
Curaçao Gaming Authority, no. OGL/2024/1944/1124
Every welcome bonus has one term that does most of the damage. At some casinos it is the multiplier, at others the max bet. At Gravira it is the calendar. Here is what five days actually means for a C$1,000 match.
Gravira's Canadian offer at present: 100% up to C$1,000 + 100 free spins.
A four-deposit welcome bonus. The record we keep covers the first stage in detail; the package total covers all four. From Canadian sources (the operator blocks automated readers):
| Term | Value |
|---|---|
| Match | 100% on the first deposit |
| Bonus cap | C$1,000 (C$5,000 across four deposits) |
| Free spins | 100 on Gates of Olympus (330 across the package) |
| Wagering | 35x the bonus; 40x on spin winnings |
| In money, sample deposit | C$100 deposit = C$100 bonus = C$3,500 in bets |
| Minimum deposit | C$30 |
| Max bet with bonus | C$7 |
| Expiry | 5 days |
| Conversion cap | 10x the bonus |
The positives are real. Wagering at 35x the bonus alone undercuts the usual 40x and leaves your deposit out of it. The C$7 max bet gives room to move.
Now the calendar. Five days for C$3,500 of betting is C$700 a day. At the full C$1,000 bonus it is C$35,000 in five days - C$7,000 a day, or about 1,000 spins daily at the max bet. Put your real deposit into the wagering calculator before you opt in.
Two caps follow. Bonus winnings convert to cash only up to 10x the bonus - C$1,000 on a C$100 bonus. And spin winnings carry their own 40x and are capped per stage, so the 100 free spins on Gates of Olympus are worth less than the number suggests.
The regular offer is a weekly cashback of up to 25%, with the rate climbing by loyalty level. It carries 15x wagering, and Canadian sources report a cap on cashback winnings of 3x the cashback. A new player starts at a lower rate than the headline.
Deposit C$200 and the match adds C$200, with 100 spins on Gates of Olympus. The bonus needs C$7,000 of betting in five days: C$1,400 a day. At C$2 a spin, that is 700 spins daily; at the C$7 limit, 200. Spin winnings have their own 40x on top. If everything clears, the 10x conversion cap holds bonus-derived cash to C$2,000.
Claim it if you already play several hundred spins a day and your deposit sits around C$100-200: the 35x basis is fair and five days of your normal play may cover it. Skip it if you play in short weekend sessions, prefer table games, or would need a big deposit that pushes the daily target past what you normally bet. For most players the weekly cashback is the better long-term hook: up to 25% back, rising with loyalty level, at 15x.
Short-burst, high-volume players. If you already play several hundred spins a day, five days is manageable.
Players who want Interac withdrawals - Gravira takes Interac both ways, which keeps casino money in a familiar channel.
Regulars who will climb the loyalty ladder for a better cashback rate.
It does not suit a weekend player who deposits on Friday and plays a bit each day. Gravira's bonuses are available for players outside Ontario and Alberta. Jackpot City pairs the same 35x basis with seven days per deposit instead of five.
| Casino | Welcome match | Wagering | Window |
|---|---|---|---|
| Gravira | 100% up to C$1,000 + 100 spins | 35x bonus | 5 days |
| Jackpot City | 100% up to C$400 | 35x bonus | 7 days |
| CasinOK | 100% up to C$2,000 | 35x bonus | 30 days |
| 20Bet | 100% up to C$120 + 120 spins | 40x bonus | 14 days |
Three casinos here charge 35x on the bonus. Gravira gives the least time to do it - a sixth of CasinOK's window.
About 6,000 games, the lower stated figure among Canadian sources (another counts 8,500+). Provider counts range from 26 to 95 depending on the source, so we print none.
Gates of Olympus is the welcome spin game. Gravira sits in our new casinos list and its lobby is mid-to-large by current standards. Mobile play is browser-based, with no native app.
Because spin winnings carry their own 40x on top of the 35x match wagering, it pays to treat the 100 spins as part of the playthrough rather than a separate prize. Their results feed a second requirement with its own per-stage cap, so a strong spin session adds betting as well as balance.
Gravira takes Interac e-Transfer, Visa, Mastercard, Apple Pay, Google Pay, and five coins: Bitcoin, Ethereum, Litecoin, Tether and USD Coin.
Interac covers deposits and withdrawals; Apple Pay and Google Pay are deposit routes, so plan to cash out by Interac or crypto if you pay in with a mobile wallet. Canadian sources give a C$50 minimum for Interac withdrawals and a C$15 minimum deposit outside the bonus.
Withdrawals take about 24 hours on our record; one Canadian source quotes 0-12 hours. The coin range places Gravira on our crypto casinos list, and our Interac casinos guide compares sites with Interac withdrawals.
Gravira is operated by Horizonix Corp N.V. (reg. 166811) under Curaçao Gaming Authority licence OGL/2024/1944/1124. The brand launched in 2025, so its track record is short.
Curaçao remains a lighter regulator than Kahnawake, which is worth weighing if you plan to hold a large balance on site. The casino licences guide explains the difference.
Support is on live chat 24/7. A five-day bonus window can push longer sessions than you planned; session reminders and loss limits on our responsible gambling page help keep it in hand.
In short: Gravira's maths is friendly, its calendar is not. Size the bonus to five days of real play, keep within C$7, and lean on the cashback for the long run.
Expected cost = total bets x (100% - RTP). Assumes slots at 96% RTP and every bet counting 100% toward wagering; caps on winnings ignored. Real sessions swing far above and below the average.
Each part out of 10, from published terms and cross-checked sources. How we rate
Gravira has a fact sheet in one section of the site, each with the offer for that country's players.
Best for: Canadian players who play a lot in short bursts and want Interac withdrawals plus a loyalty-linked weekly cashback.
Gravira gets the multiplier right and the clock wrong. 35x on the bonus only is one of the friendlier rates on our Canadian list, and a C$7 max bet is workable. But five days per stage, a 10x conversion cap and 40x on spin winnings make the package tighter than its headline. The weekly cashback and Interac withdrawals are the lasting reasons to stay.

35x the bonus. A C$100 deposit matched 100% means C$3,500 in bets within 5 days, at a C$7 max bet.
Bonus conversion is capped at 10x the bonus. On a C$100 bonus the most you can convert to cash is C$1,000. Spin winnings are also capped per stage.
Weekly cashback of up to 25%, with the percentage rising as your loyalty level goes up. It carries 15x wagering.
Yes. Interac e-Transfer works for deposits and withdrawals; Canadian sources give a C$50 minimum for Interac withdrawals. Apple Pay and Google Pay are for deposits.
