Three numbers that describe a slot
| Number | What it tells you | Where to find it |
|---|---|---|
| RTP | long-run return; 100% minus the house edge | game info screen |
| Volatility | how often and how big wins come | studio page or info screen |
| Max win | the ceiling of one spin or bonus | studio page or info screen |
A slot at 96.5% with high volatility and a 5,000x max win will feel very different from one at 96.5% with low volatility and a 500x cap, even though both return the same over time.
Three slots Canadians play
| Slot | Studio | RTP | Volatility | Max win | Released |
|---|---|---|---|---|---|
| Sweet Bonanza | Pragmatic Play | 96.51% | medium to high | 21,100x | June 2019 |
| Gates of Olympus | Pragmatic Play | 96.50% | high | 5,000x | February 2021 |
| Big Bass Bonanza | Pragmatic Play | 96.71% | medium to high | 2,100x | December 2020 |
All three come from Pragmatic Play, the studio most crypto casinos carry. For other studios, see game providers.
Check the version
Studios ship several RTP versions of the same slot and let the casino choose. Gates of Olympus, for example, exists at 96.50% and 95.51%. The difference is small per spin and large over thousands. Open the game's info screen at the casino before you play; if it shows the lower version, consider a different casino or a different slot.

Crypto slots from Canada: the cost of a session
A slot's RTP gives the average cost of play. At 96.5%, every C$100 wagered costs about C$3.50 on average; at 94.5%, it costs C$5.50. That is why the version matters more than almost anything else on the info screen. Volatility decides how far a session strays from that average. A high-volatility slot can end a session well up or well down; a low-volatility slot keeps closer to the average.
| RTP | Average cost per C$100 wagered |
|---|---|
| 96.71% | C$3.29 |
| 96.50% | C$3.50 |
| 95.50% | C$4.50 |
| 94.50% | C$5.50 |
Bitcoin slots, USDT slots
Slots at crypto casinos are the same games as anywhere else; the balance is in coins. Playing in Bitcoin adds the price of Bitcoin to your result: a session that breaks even in the game can end up or down in dollars. Playing in USDT keeps the result in dollars. Our volatility article works through both with real numbers.
Slots and bonuses
Slots usually count 100% toward bonus wagering, which makes them the default way to clear a deposit bonus. Read our bonus guide and wagering guide before accepting one. If you prefer faster, simpler games, the crash games section has five of them.
The slots streamers play are the same ones you can play: see Canadian casino streamers and are casino streams real money?. Two studios behind many hits: Pragmatic Play and Hacksaw Gaming.
Questions and answers
What are crypto slots?
The same online slots you find at any casino, played with a crypto balance. A few crypto casinos also make their own slots, but most titles come from studios such as Pragmatic Play, Hacksaw Gaming and BGaming.
What is RTP in slots?
Return to player: the share of all stakes a slot pays back over a very long run. A 96.5% slot keeps about 3.5% on average.
Why does the same slot have different RTPs?
Studios offer several versions, for example 96.50% and 95.51% for Gates of Olympus. The casino chooses which one it runs. Check the info screen in the game.
What is volatility?
How a slot pays: low volatility gives frequent small wins, high volatility gives rare big ones. It does not change the RTP.
What is max win?
The largest multiple of your stake a single spin or bonus round can pay, for example 21,100x on Sweet Bonanza.
Are crypto slots provably fair?
Slots from outside studios use certified random number generators rather than player-checkable seeds.
What is bonus buy?
An option to pay a set price, often 100x the stake, to go straight to free spins. It is not available in every market or at every casino.
Which slots do Canadians search most?
Among the big Pragmatic Play titles, Sweet Bonanza, Gates of Olympus and Big Bass Bonanza draw the most searches from Canada.
Do slots count toward bonus wagering?
Usually in full, which is why slots are the standard way to clear a casino bonus.
What stake should I use?
Small enough for at least 100 spins in a session, more on a high-volatility slot.
