How to play Grizzly Strike mobile slot

The Grizzly Strike slot is a 5×3 reel, 20 payline game created by Iron Dog Studio. Open it up, and you’ll find Grizzly Expanding Wilds, Free Spins, Instant Wins up to 1,000x bet, a Hold & Win feature, and a 5,100x bet max win.

Set deep in the woods; you’ll find the Bison, Elk and Mountain Lions as the high-paying symbols paying for finding two or more, with A, K, Q, J, 10, and 9 low-paying symbols which pay for finding three or more.

At first glance, it might look like a simple five reel with a good-looking animal theme, but this slot hides a few exciting features, all created to help entertain and reward you with wins.

The Grizzly Strike Feature adds Extra Wins

When 2 or more Grizzly Wild symbols show up on a winning payline, they’ll battle it out with one of them expanding and the others running away in fear leaving behind wild symbols in its wake.

As it runs, it can run into another Grizzly wild, creating a multiplier or collect the money values if it runs into a Special Golden Nugget symbol.

It’s a feature that shows up often, adds extra action to your base game and free spins bonuses, and can help top up your casino balance.

Talking about topping up your balance, you’ll instantly win a prize if you find three or more of the rare Special Strike Nuggets. A prize could be 50x, 250x or 1,000x your bet for finding 3, 4, or 5 symbols, respectively.

Action packed with Free Spins & Hold & Win

There are two more bonus features that can add to your winning ability. The first, which is usually the feature where you can win the game’s biggest wins, is the free spins.

These are just your standard free spins, nothing special here, except you can retrigger more free spins and the Hold & Win feature.

The second is the Hold & Win feature, where the Special Golden Nugget symbols can payout their values.

Triggered by finding six or more nugget symbols, you’ll get an initial three spins to try and land nugget symbols on the screen. Do that, and you’ll reset the respins, but find none for three spins in a row, and you’ll end the game.

It’s a feature that can reward some generous payouts, especially as you could get a 5x win multiplier applied if you have 5 Special Strike Nuggets on screen.

In-game bonus features

Wilds: The Grizzly bear is the wild symbol and substitutes for all other symbols except Scatters, Special Golden Nugget, and Special Strike Nuggets.

Grizzly Strike Feature: 2 or more Grizzly Wilds on a winning line trigger the Grizzly Strike feature. At the start, one Grizzly will expand to fill the entire reel and scares off the other Grizzlies on the winning line, leaving wilds behind as they run. If the Grizzly runs into another Grizzly, it'll add a multiplier. If it runs into a Special Nugget, it will add the value on it to your win.

Special Strike Nuggets: Appearing on all reels, 3 or more Special Strike Nugget symbols will award instant wins.

  • 3 = Mini Payout of 50x bet
  • 4 = Minor Payout of 250x bet
  • 5 = Major Payout of 1,000x bet

Hold & Win: A combination of 6 or more Special Strike Nugget or Special Golden Nugget symbols triggers the Hold & Win feature. You'll start with 3 respins where if Special Strike and Special Golden Nuggets land, they'll reset your spins back to three. The game ends when all positions are filled, at which point a 2x multiplier is applied or when there are no more respins. If 5 or more Special Strike Nugget symbols are on screen, a 5x win multiplier is applied.

Free Spins: 3, 4, or 5 scatter symbols trigger 5, 10 or 15 free spins. Free Spins can be retriggered, and the Hold & Win feature can also be awarded during the free spins.


  • Win up to 5,100x stake
  • Instant wins up to 1,000x bet
  • Hold & Win feature


  • Low 94.44% RTP

Grizzly Strike Review Conclusion

Iron Dog Studio surprised us with their Grizzly Strike slot on mobile. Its Grizzly Strike feature with the Expanding Wilds shows up often in the base game, while the potential for those instant win prizes, Hold & Win or free spins to hit adds value to your spins.

A 0.20 minimum bet up to a maximum of 50 per spin gives you plenty of room to mix and match your bets while you wait for the slot features to hit.

If you're a fan of animal-themed slots that come with lots of features, you'll enjoy a few spins on this game, but it might just get lost to other great slots like the Wild Hike slot from Relax gaming or the Great Bear slot from IGT.

Take it for a spin at one of our best online casinos and see how many features you can trigger.
