Yggdrasil Gaming has expanded its portfolio with the release of Coo Coo Cashoo with LightningLines™, marking the second title developed using the company's innovative Game in a Box™ technology.
Set within a bustling clock shop, the game introduces players to Ben, the overworked proprietor who oversees the action across the reels. The slot's standout feature is the newly developed LightningLines™ mechanic, which dynamically adjusts the number of symbols on each reel from two to seven, creating up to 117,649 ways to win.
The game operates on 6×7 dynamic reels populated with mechanical clocks, buzzing gadgets, and Coo Coo Wilds that facilitate combination completions. Punch Clock Multipliers enhance the gameplay experience, while Free Spins maintain locked multipliers for enhanced winning potential.
Game in a Box™ Technology
Yggdrasil's proprietary Game in a Box™ platform enables coordinated gameplay elements that synchronize mathematical models, visual presentation, and audio responsiveness. Coo Coo Cashoo marks only the second title developed using this innovative technology.
During free spins, scatter multipliers accumulate without resetting, with each scatter symbol throughout all spins contributing to the multiplier total. This mechanism enables a maximum win potential of 5,323x the stake.
The title distinguishes itself through reactive audio technology, where the soundtrack responds to on-screen action during each spin, creating an immersive gaming environment that evolves with player interaction.
"It was a blast working on Coo Coo Cashoo. It was a rare occasion where each element of a game is coordinated to work with each other. The gameplay math model is highlighted by the animated visuals; the visuals are supported by a reactive audio track; the audio track follows the flow of the gameplay."
— Ricardo Viana, Executive Creative Director at Yggdrasil
Coo Coo Cashoo joins Yggdrasil's core game lineup alongside established titles including Vikings Go To Valhalla, MexoMax, and Raptor 2.
