This is not the first time we meet ELK’s quirky troll family, but it’s the most memorable experience thus far. Book of Sam follows the charming creatures on their holiday to Las Vegas, and the neon-infused setting is far more engaging than the forest and beach settings in predecessor installments. You really feel like you’re going with them on the trip thanks to the immersive intro and visuals, and it’s a joy to see what can be done with the Egypt theme with a bit of imagination added to the mix.
Players can join Sam's clan in trying their luck on any device in two different modes – Normal or Bonus mode. Normal mode means picking a stake of €0.20 to €100 per spin and banging away on the play button. Bonus mode is enacted by clicking the X-iter button and choosing one of the five options. Both modes have a theoretical return value of 94% and are highly volatile. While packed with more features than a regular 'Book of' slot has, Book of Sam's grid setup is completely standard, consisting of 5 reels, 3 rows, and 10 paylines.
Regular wins begin on the leftmost reel, paying left to right on consecutive reels. At least three are needed for the low pay 10-A card rank symbols, or at least two for the higher value cat, Maggie, Sandra, or Sam symbols. Hitting a five-of-a-kind win awards 5-9x the bet for the lows, increasing to 10 to 500 times the stake for the premium symbols. Book of Sam comes with a book symbol, and as you might have guessed, it is the wild and the scatter. In its task as wild, the book can replace any pay symbol, or if making a winning line of only wilds, it is worth the same as Sam.
Book of Sam comes with free spins where chosen symbols expand, plus three varieties of Electric Treats and five options from the X-iter menu to cover.
Electric Treats are available in the base and bonus game. They are triggered when one of the troll family members creates a win, like so:
Landing 3, 4, or 5 book scatters in normal mode awards 8 free spins with 1, 2, or 3 expanding symbols, respectively. Pay symbols are randomly chosen to be expanding symbols. After regular win evaluations, expanding symbols spread to cover all positions on their reel. You'll need at least two high-pay or three low-pay expanding symbols on individual reels to do so. Once expanded, these symbols pay all ways from any position.
Should 3 or more book symbols land during free spins, extra free spins are awarded plus 1 more expanding symbol, up to 5 expanding symbols at the most. Electric Treats can be activated in free spins, too. Sandra's multiplier is persistent through free spins but is only active during an Electric Treat. It deactivates when the Treat ends but is reactivated by a new Electric Treat. If Electric Sam triggers, the book symbol is also an expanding wild during the respins.
If present within the game, players can click the X-iter button to enter feature buy mode, where they can choose one of these options.
Once into the bonus round, the Treats tended to trigger more frequently, and when they did, they had the ability to integrate with the expanding symbols feature rather well. Expanding symbols are the heart and soul of any 'Book of' slot, and here they get the chance to sparkle with up to five expanding symbols at once. Or, fork out 500x the bet to buy the Super Bonus from the X-iter, where every single pay symbol is an expander. The X-iter options were positive additions, too, nicely fitting to the features rather than the other way around. They give eligible players a chance to instantly sample some of the finer things Book of Sam has to offer or, taking it one step further, the finer side of what 'Book of' gaming, in general, has to offer. The final frosting is a win cap of 10,000x the bet, meaning the extra bells and whistles aren't just for show, though the return to player value is such that it might sour the experience for some.
Book of Sam's gameplay on its own felt good enough to draw 'Book of' fans in for a look, but it's also been wrapped up in an attractive package, something ELK Studios is good at doing. The lower-than-average RTP is a drawback, the jazzy attitude, the bright lights of Sam Vegas, and the pacey mix of old and new elements added up to a slot that injects life into the 'Book of' category.
