How To Play Book of Sam Mobile Slot

The Book of Sam slot brings you expanding scatter pays but with three added bonus features to stand out from the crowd.

The Trolls are back and headed for the all-you-can-play buffets of Vegas! First seen in the Electric Sam slot and the sequel Sam on the Beach review, Elk Studios bring you a fun theme where fun-loving trolls get up to no good around the world.

The Book of Sam mobile slot gives you 10 paylines where 2 high-paying symbols can trigger either avalanching wins, multipliers, respins or extra wilds. But it’s the 3 scatters and the 10 free spins with expanding scatter pay that are still the star of the show.

If you think that sounds very similar to the Book of Dead slot or any of the many copies, that’s because it’s exactly what you are getting. Instead of Egyptian Pyramids, you have Vegas Pyramids and three cheeky trolls filling up your wallet.

The Book of Sam slot main slot features:

The three highest-paid symbols on the paytable are Sam, his wife Sandra and their daughter Maggie. They pay well by themselves, but getting any 2 of the same symbols on the reels will trigger any one of the following features:

  • 2 Sam’s: Adds 1 wild symbol onto the reels and gives you respins with the wild sticky
  • 2 Sandra’s: Multiplier is increased, and you get respins with the multiplier active
  • 2 Maggie’s: All low-value symbols are removed

You can get other pairs of troll symbols and have multiple features in a row, giving this Book of Sam game a quick action feel that almost makes you forget that you are losing slowly.

A mid to high variance slot by Elk Gaming studios

All this passes the time until you hit three books wild and scatter symbol and trigger 10 free spins with one expanding scatter pays – much like in the Legacy of Dead slot.

This time, Sam, Sandra and Maggie can give you an extra boost, allowing you to get wins of up to 10,000x your bet, especially if you manage to trigger sticky multipliers throughout the bonus games.

Unfortunately, the RTP is a low 94%, which is much lower than so many other Book of games, like Book of Oz slot or the Book of Golden Sands review.

But you do have multiple features and the ability to catch multiple expanding scatter pay symbols, which you don’t often get, with a mid-to-high variance that keeps things interesting.

Book of Sam Bonus Features

The Wild Scatter Book: The book symbol is both the wild and the scatter symbol. It replaces other symbols to create wins over this 10 payline slot or triggers the free spin bonus.

Maggie Electric Treat: Two or more Maggie symbols on the reels will trigger this bonus. Once pays have been calculated, all the low-value symbols, including the cat and Maggie symbols, are removed, allowing more symbols to drop from above.

Sandra Electric Treat: Two or more Sandra symbols will increase the game multiplier and award respins.

Sam Electric Treat: Two or more Sam symbols, adds a Wild Book symbol, and awards respins. The book symbols are sticky during respins.

Scatters and Free Spins: 3 or more book symbols on the reels will trigger 10 free spins. However, 3, 4, or 5 book symbols will add one, two or three expanding scatter pay symbols, respectively. These expanding scatter pay symbols are paytable symbols that expand and cover the reel to give you wins regardless of where they land on the reels over all 10 paylines.

You can retrigger the bonus with three or more bonus symbols; each retrigger will give you a new expanding scatter symbol, up to a normal 5.

The Electric Treats can trigger during the bonus game, except the Sandra Multiplier is persistent throughout the entire bonus game, but only during the electric treats (i.e. if Maggie or Sam show up).


  • High 10,000x bet maximum win
  • Wild Scatters
  • Free Spins with expanding scatter symbol


  • Low 94% RTP

Book of Sam Review Conclusion

We love it when we get a new version of our favourite Book of Ra Deluxe slot, but as there are so many versions, we need something new to pique our interest.

The Book of Sam slot on mobile does just that thanks to three bonus features that give you respins, multipliers and avalanching reels at any point.

If only the RTP had been a little higher, we could have given this Elk Slot review 4 stars. As it is, this is an enjoyable machine that is easy to play with plenty of features.

That said, video slots like The Pyramids of Dead review give you similar mechanics, equal top wins but a higher RTP. For that reason, we think the Book of Sam won't stand out amongst all the other 'book of' reviews.

Expert Rating: 3 / 5
A solid slot with good wins and reliable mechanics. It may not break new ground, but it's worth a spin
