Big Brown is a slot machine by Endorphina. According to the number of players searching for it, Big Brown is not a very popular slot. Still, that doesn't necessarily mean that it's bad, so give it a try and see for yourself, or browse popular casino games.
To play for free in demo mode, just load the game and press the 'Spin' button. You can learn more about slot machines and how they work in our online slots guide.
Big Brown does not have an especially new theme. It draws on the animals and setting of the Rocky Mountain wilds.
Most slots that take this theme use a style that references a uniquely American type of spray-painted mural. Here that style is preserved, but given a slightly hand-painted veneer, it elevates the theme and gives the Rocky Mountains a more epic feel and classy style.
If you enjoy the idea of a mountain hike or have ever been moved by the majesty of the big brown bears of the U.S., then this slot may just be for you.
Set in the majestic Rockies of the United States, Big Brown draws on the classic art style of slots like this—the patriotic mural.
Each animal has a small animation that triggers when it wins, but the rest of the slot is pretty inert. There are basic win and spin graphics, but little other movement.
The soundtrack is ambient forest noises and piping music that evokes movies in the Western genre. Even the reel sounds have the natural sound of wood tapping on wood.
Overall, the slot's visuals and soundtrack do a good job of drawing players into the wilderness experience of the slot.
Big Brown is played on a big canvas, reflecting the landscapes that inspired the slot. There are six reels of four symbols each.
That makes for 24 symbols on each spin and 4,096 ways to win, thanks to the any-way-wins system that Big Brown uses.
When the player wins, they can use the double or nothing game to gamble their winnings. However, it is worth noting that the Gamble Feature has a return of just 84%, greatly impacting the cost of the game.
The maximum win on any given round is capped at a decent 9,000x the player's bet.
Big Brown has two Wild symbols. The Wild symbol substitutes for all symbols except the Scatter and Raging Wild. The Raging Wild works like the Wild symbol but doubles any win it is a part of.
Landing three or more Scatters will trigger the Free Spins Bonus. Three symbols give the player eight free spins, with the number increasing for every additional Scatter the player lands.
The maximum number of free spins is 24 for six Scatters. However, the Free Spin Bonus can be retriggered if the player lands three or more Scatters on a Free Spin.
The return to player (RTP) of the basic game in Big Brown is 98.08%. This is way above our yardstick for an average of roughly 96%.
However, playing with the Bonus Pop on reduces this to between 93.97% and 95.85%, this is too low and a good reason to turn Bonus Pop off, no matter how tempting the increased chance of hitting a Bonus is. As for the Gamble feature with its 84% RTP, avoid that like you would a bear in the woods.
The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.50 up to a maximum of $/£/€12.50 per spin.
We love that Big Brown is a high volatility slot as it means that this slot is a great match for our preferred slot machine strategies. Just remember to maximize the RTP with the game options.
With high volatility and a magnificient RTP of 96.08%, this slot has great stats for use with our preferred slot strategies.
The theme is handled well (if unimaginatively), and the slot hangs together decently enough.
If you enjoy the American wilds, this could be a good slot for you.
