Rock and Rubbles by Gameplay Interactive is a prehistoric-themed online slot with a 3x3 reel layout and a single active payline. The game uses numbered stone-style symbols, while the middle reel carries arithmetic operators that determine whether the outer numbers are added or multiplied. The result is then tied to the line bet.
The paytable shows scatter variants including SCATTER PLUS and SCATTER MULTIPLIER, which are linked to bonus features and free spins. The interface presents a caveman setting, jungle background and carved control panel, with options for line bet adjustment, max bet and auto spin. Players can use the demo version to play for free and practice before playing for real money.
