Book of Jurassic Slot by Amigo Gaming

Two weeks after Book of Amigo launched with its Western saloon look, the same engine got a prehistoric makeover. Identical core - one book symbol that acts as wild and scatter, 10 free games with a randomly chosen expanding symbol, retriggering via three more books. The difference is three progressive jackpots bolted on top: Grand, Major, and Minor, all server-managed with undisclosed trigger conditions. Book of Amigo doesn't have those. So this is essentially the same game dressed in a different skin, plus jackpots.

Fiery red and orange wash over everything. The volcanic background glows through layers of tropical tree silhouettes and distant mountain ridges, all in that smoky crimson haze. Rough stone pillars - bone-like, cracked - hold the grid in place. The explorer in a safari hat sits at the top of the paytable, followed by a T-Rex framed in purple, a triceratops in green, and a pterodactyl perched near an erupting volcano in red. Card values 10 through A use a teal metallic finish with orange edges, chunky enough to read against the dark reel strips.

Free games work the same way they do in every "Book of" slot. Three books land, 10 spins start, one symbol gets selected at random as the special expanding symbol. During those spins, if the chosen symbol lands and can form a winning combination on a payline, it stretches to fill all three rows on that reel. Get the explorer selected and land him across three adjacent reels - he fills them top to bottom, paying across all 10 lines. If the expansion wouldn't create a win, the symbols just stay in their original positions. Three more books during the round add another 10 spins, and a new expanding symbol gets picked for the extension.
