Rock Vegas, an engaging online slot game crafted by Pragmatic Play and Reel Kingdom, offers a unique blend of humour and adventure set in a prehistoric theme. This game features a 5-reel, 3-row layout and provides players with 20 different ways to secure a win. Players are greeted by a comical caveman character, reminiscent of Gonzo from Gonzo's Quest, who adds a light-hearted touch to the gameplay. In contrast, the reels are adorned with a variety of wild beasts, adding a sense of thrill and excitement.
In the base game of Rock Vegas, players aim to match symbols from left to right across adjacent reels, starting from the leftmost reel. The game includes nine regular paying symbols. The lower-value symbols are represented by the classic 10-A royals, offering payouts ranging from 3.75 to 6.25 times the player's stake for a combination of five identical symbols. The higher-value symbols, referred to as 'crazy beasts,' include lizards, white tigers, and cavemen. Landing a line of five high-value symbols can reward players with 12.5 to 37.5 times their bet. Notably, despite its 'wild' theme, Rock Vegas does not feature any wild symbols within the game.
The primary focus of Rock Vegas is its unique Hold & Spin feature, which is activated when at least three scatter symbols appear on the reels. Upon triggering this feature, the standard base game reels vanish, and players are presented with a new 10x10 grid. This grid exclusively features coloured rock symbols and blank spaces. Each colour of rock carries its own value: blue rocks are worth 0.1x the bet, green rocks 0.2x, yellow rocks 0.4x, pink rocks 0.6x, and red rocks 1x the bet.
The variety of rocks that appear during the bonus round depends on the number of scatter symbols that triggered the feature. Three scatters allow all rock colours to appear, four scatters eliminate blue rocks, and five scatters remove both blue and green rocks. The bonus round starts with three respins, during which any landing rock symbols lock in place and reset the respin count back to three. This process continues until no more respins remain or the grid is filled with rocks.
