Quick verdict

Book of Buffalo puts a fresh spin on over-used slot tropes to solid if slightly unspectacular results. A solid RTP and some high volatility help to compensate for a modest maximum win, while the bonus features deliver some excitement.

Book of Buffalo review

Theme and Style

Book of Buffalo is a buffalo-themed slot designed and developed by Indigo Magic. As the name might suggest, the slot also utilizes the popular ‘Book of’ gameplay mechanic.

Graphics, Sounds and Animations

The Great American Plains is a popular source of inspiration for slot developers, and Indigo Magic is taking us out there once again for the Book of Buffalo online slot.

The genre lends itself nicely to rich designs, and Book of Buffalo is definitely one of the more attractive on the market. The slot has a brilliant 3D-like design that brings its symbols, which consist of wildlife from the plains, to life in an effective manner. An eagle, bear, cheetah, and, of course, the buffalo, all make appearances.

A Western-style soundtrack plays as you spin the reels, while a majestic buffalo stands just off to the right of the game grid.


Book of Buffalo has a conventional base-game set-up. The action begins in a 5x3 grid with 10 paylines. Winning combinations are formed from left to right for three or more matching symbols. As the reels expand with the bonus features, so do the number of ways to win.

At 5x4, there are 15 ways to win, at 5x5, there are 20, and at 5x7, there is 50, which is the maximum available.

Wilds, Bonuses and Free Spins

The main focus in the Book of Buffalo slot is the Free Spins round. This is triggered by landing three or more Scatters.

When the round is triggered, players select a symbol to expand. If this lands as part of a win, it will expand to cover its reel. These symbols also no longer need to be adjacent when expanded, becoming a scatter pay.

The game grid can expand by collecting Scatters during this round. Three scatters expand it to a 5x4 grid with 15 paylines, seven expand it to 5x5 with 20 paylines, and 12 expand it to 5x7 with 50 paylines. You will be rewarded with three, two, and one spin at each level, respectively.

It is also possible to have an expanded symbol during the base game. On any spin, a normal symbol can be expanded using the Stampede feature. This feature also guarantees a win-spin.

At the start of the Free Spins bonus, players are given the chance to gamble their spins. This can not happen if they are already at the maximum number of 18 spins.

Depending on your location, the possibility to buy a bonus may be available.

Bet Sizes, RTP and Variance

Book of Buffalo has a good math model. The maximum win is 7,490x your bet. This can be won if you select the Buffalo as the expanding symbol in the Free Spins round. This also puts the game at its highest level of volatility. In general, the game is considered highly volatile. It has an RTP of 96.28%, which is a good amount according to our slot strategy guide.


With Book of Buffalo, Indigo Magic has attempted to put a fresh spin on two of the most common themes in slots: the buffalo and the ‘Book of’ features. For the most part, the game is a success, with the option for players to choose their own expanding symbol and, in turn, their volatility, helping the ‘Book of’ features feel fresh. While it is not quite as innovative as titles like Book of Books, it is still an enjoyable twist on old themes.

The math model in the game is quite attractive, with a strong RTP and some high volatility. However, the maximum win of just under 7,500x your stake is not likely to get pulses racing.
