Our Verdict
Grug Make Fire is a high-volatility slot from Hacksaw Gaming with a 96.19% RTP, a 5x4 grid, and a max win of 10,000x your bet. It's built for players who can sit through dry spells and still get excited when a Burning Wild lights up a reel. If that sounds like you, it's worth your time.
The Burning Wild mechanic is genuinely interesting. Low pays become wilds. Premium symbols transform into Burnt Wild Multipliers worth anywhere from x2 to x200. Two separate bonus rounds give you different ways to chase the bigger numbers. This isn't a slot that just spins and pays lines quietly. Things actually happen on screen.
That said, high volatility is not for everyone. Losing runs can be long and expensive before a feature pays anything meaningful. The 96.19% RTP is a long-run theoretical figure across millions of spins, not a session promise. Players who prefer steadier returns or smaller swings should look elsewhere. But if you're comfortable with the risk, Grug Make Fire has more going on than most slots in its class.
What We Like and Don't Like
Pros
- Burning Wild mechanic actively changes the symbols on the reel, so each spin can shift quickly from nothing to something significant.
- Burnt Wild Multipliers range from x2 to x200, giving the base game real win potential without needing to trigger a bonus.
- Two distinct bonus rounds (Grug Find Food and Grug Fight Dino) offer different experiences, with the Dino round adding Burnt Reels and a Wildfire progression bar.
- RTP of 96.19% is competitive for a high-volatility slot, and Hacksaw publishes multiple RTP variants so operators can disclose which version they're running.
- Bets start at $0.10 CAD, which keeps it accessible for players who want to manage exposure carefully.
Watch-outs
- High volatility means you can spin through a significant portion of your session budget before a feature lands, or before a feature pays anything worth talking about.
- The Feature Buy option costs up to 200x your bet. That's a large single outlay, and it doesn't change the odds of what the bonus pays once you're in it.
- Some operators run lower RTP variants (as low as 86.22% according to Hacksaw's own published figures), so check which version your platform is offering before you play.
- Availability depends on your operator and province. Not every platform listed carries the game, and access rules vary under iGaming Ontario's framework.
RTP, Odds and What They Actually Mean
RTP stands for return to player. Grug Make Fire's published RTP is 96.19%, which means that over tens of millions of spins, the game is designed to return roughly $96.19 for every $100 wagered in aggregate. The remaining 3.81% is the house edge. That's the mathematical cut the game keeps over time, and it's built into the RNG before you ever press spin.
What RTP is not: a session guarantee. It's not a promise that you'll get 96 cents back on every dollar in your next hour of play. In a high-volatility slot, a single session might return 0% or 400%, because the math plays out across a distribution that includes a lot of small wins, occasional medium wins, and rare but large bonus payouts. Your 200-spin session is a tiny sample. The 96.19% figure only stabilises across a population of millions of rounds.
The house edge here is 3.81%. That's the gap between 100% and the RTP. It's not hidden, and it's not negotiable. Every spin you make contributes to that edge over time. Knowing it doesn't change it, but understanding it helps you set realistic expectations about what the game can and can't do for your bankroll.
In terms of what wins actually look like: the paytable runs from royals (10 through Ace) paying 1x stake for five of a kind, up to premium prehistoric creature symbols paying 2.5x to 10x for five of a kind. A five-of-a-kind Burning Wild pays 10x. The meaningful money in this game comes from Burnt Wild Multipliers (x2 to x200) stacking with premium symbols during features, not from base-game line pays. These are illustrative based on the published paytable and RTP; actual session results will vary.
Hacksaw Gaming also publishes lower RTP variants of this game, specifically 94.28%, 92.27%, and 86.22%. The 96.19% figure applies only when the operator is running the standard version. If you're playing on a platform that hasn't disclosed which variant is active, that's worth asking about. It's a meaningful difference over time.
Fairness and Round Independence
Grug Make Fire runs on a certified random number generator. Each spin is generated independently, with no connection to any previous spin or future outcome. The game has no memory. A bonus round that paid 500x on the last spin doesn't make the next one more or less likely to trigger. A long run of dead spins doesn't mean a win is due. That's not how RNG works, and it's not how this game works.
Hacksaw Gaming is a licensed provider that submits its games for independent testing by certified labs. That process verifies that the RNG behaves correctly and that the published RTP figures are accurate over the long run. When you play on a regulated platform under iGaming Ontario, you have additional protections because the operator is required to offer games that meet AGCO standards. That's a real layer of accountability, not just a marketing claim.
On the topic of predictor apps, hack tools, and signal bots: none of them work. There is nothing to predict. Each spin outcome is determined at the moment you press the button by an RNG that produces results no external software can access or anticipate. Apps that claim to predict Grug Make Fire results are either selling false promises or outright scams. The only thing they'll reliably do is waste your money before the game even gets a chance to.
Volatility and What It Feels Like
High volatility means the win distribution is uneven. Most spins pay little or nothing. The game is designed so that value concentrates in less frequent, larger events, specifically in the bonus rounds and in Burnt Wild Multiplier combinations. In practice, that means you can spin through 50 or 100 rounds without anything significant happening. Then a Burning Wild hits at the right moment, a premium symbol burns into a x100 multiplier, and the picture changes fast. That's the deal with high-volatility slots, and Grug Make Fire is an honest example of the type.
The speed of play matters here. Slots move quickly. A $200 CAD session budget at a $2 bet per spin can disappear in under 20 minutes on a bad run, faster if you're using the Feature Buy. The pace doesn't give you much time to notice how quickly things are moving. Setting a loss limit before you start, and sticking to it, is the only real protection against a session running away from you. If you want to think through how to structure your bets and session limits, the strategy guide covers that in detail.
Mobile Experience
Grug Make Fire plays in the browser on both desktop and mobile, so there's nothing to download or install. The game is built to scale across screen sizes, and the prehistoric art style translates well to a smaller display. The Burning Wild animations are clear enough on a phone screen that you can follow what's happening without squinting. On a decent mobile data connection or Wi-Fi, the game loads quickly and runs without lag.
If you're playing on an older device or a slower connection, the experience is generally still workable, though animation-heavy moments during the bonus rounds can occasionally stutter.

Who Should Play Grug Make Fire
This game suits players who are comfortable with variance and genuinely enjoy watching a mechanic play out. If you like the idea of a Burning Wild changing the shape of a spin mid-round, and you can accept that most spins won't lead anywhere, Grug Make Fire gives you a lot to engage with. The two bonus rounds are different enough to feel like distinct experiences, and the Wildfire progression in the Dino round adds a layer of escalation that keeps things interesting when you do get in.
Skip it if you're uncomfortable with long losing streaks, if you tend to chase losses, or if you prefer slots that pay smaller amounts more regularly. High volatility is not a style that works for every player or every session budget. It's also worth knowing your limits before you start. If gambling has ever felt like something you couldn't control, this isn't the right game, and taking a break is always a valid choice. Gambling should be entertainment. If it stops feeling that way, resources like ConnexOntario (1-866-531-2600) are available. Must be 19+ to play in Ontario.
