Bison Boom Review

Northern Lights Gaming is no stranger to this niche and we've seen them pull off similar feats with games like Bison Moon. What's the difference between a Bison Boom and a Bison Moon? Well, the moon still plays a part in this latest release but it seems that dynamite is now also an option.

Gameplay & Features

Dragging those big hairy hides across this 5x3 grid, the bison and other symbols can collect wins on 20 paylines during the regular part of the game. 

Royal symbols pay a maximum of 1x for a group of five aces while the picture symbols can grow between 2x and 8x for their respective five-of-a-kind wins. The most powerful beast out there is the bison wild symbol and these show up thanks to the mini dynamite tokens. 

As a stick of dynamite lands, it heads over to the big box of dynamite beside the reels and has a chance of triggering the Bison Wild Boom feature. As the box explodes, up to 15 wild symbols can join the attack and bring potentially large payouts.

The Bonus symbols will help complete the feature upgrade bar at the top of the screen and you'll need two of them to move you along a notch. Do this 10 times to fill one of the sections, which results in an unlocked row as you start the free spins bonus. 

Bonus Game

Some jurisdictions will allow the Upsizer option where players can purchase a number of upgrades to enhance the bonus game. 

The bonus game is officially an L&W feature, which is more re-spins than free spins. You begin with three spins and each time a special symbol lands, this goes back to 3. If you go three spins without a special symbol, it's game over. 

Moon symbols bring multipliers of your bet amount and the red ones display values up to 7x but the blue ones go beyond that figure. Collector symbols will combine all of the landed moons into one and the adder will add its own multiplier value to other moons. It's also possible to split moons into two or four separate moons and unlock extra rows so that further symbols may land.

Bison Boom - Bison Wild Boom

Bison Wild Boom

Sticks of dynamite land as a symbol overlay before jumping into the box of explosives beside the reels. When the box explodes, up to 15 wilds hit the reels.

Bison Boom - Bison Spins

Bison Spins

3 scatters trigger this Link&Win game and if you fill the upgrade meter in the base game, you’ll have some unlocked rows as well. The Upsizer option may also be available to add modifiers. You get 3 respins and when multipliers and other special symbols land, the spins are reset.

Win Potential

The wild symbols can produce some top payouts as they explode from the box of dynamite when you least expect it. On several occasions, I saw wins reach over 30x thanks to these magnificent beasts. However, the main payout potential is in the bonus game and this is hardly a surprise. There may be a direct buy in option, depending on where you live, and it has a very specific price of 71.8x your bet. You should see some fairly regular wins of a half-decent value while you play and that's all thanks to the medium volatility and generous hit rate of over 30%. The RTP is 96.15%.

Design

Bison games, and others which depict hungry wild animals from North America, were clearly designed for in-person play on the casino floor. On a smaller screen, some of the epic adventure fails to come across and the graphics seem a bit brash and unrefined. Strangely, on mobile devices, it works a lot better - this may be because the details soften as your eyes squint to appreciate everything that's on offer. The soundtrack is pretty much the same as every other game in this niche but this slot does have the added annoyance of a lady commentating every so often.

Our Verdict

It feels like we've been here hundreds of times with various developers over the years and even Northern Lights is no stranger to the theme. It's hard to get excited about the design or the storyline but the win potential is sizzling away under the surface like the taper on one of those sticks of dynamite.
