NetEnt also attaches its Elevate suite of paid bonus-entry and feature-boost options

NetEnt also attaches its Elevate suite of paid bonus-entry and feature-boost options. That reflects the wider industry move toward giving players direct routes into bonus play rather than waiting for natural triggers.

For NetEnt, now part of Evolution’s game-supply operation, Demon Beats fits a pattern. The studio tends to iterate on proven mechanical families rather than pivot into adjacent categories such as crash or instant-win formats. The Avalanche engine is a durable part of the studio’s identity, and returning to it positions Demon Beats as a portfolio continuation rather than an experiment.

The two companies began collaborating in November 2025. As part of the deal, Polymarket provided data for a dedicated prediction market section on Yahoo Finance. The feature provided market-based probabilities of economic, political, and financial developments alongside Yahoo Finance content. 

The Yahoo Finance prediction market section was taken out in April. The companies have now confirmed that the larger deal is also off, as reported by Bloomberg. 

Yahoo said Polymarket is still an advertising partner and suggested the two could collaborate on other projects in the future. Polymarket has not provided any public explanation for the end of the data partnership.

The proposition is already being tested commercially. Live casino supplier Eeze has become the first supplier to utilise Studio in a Box as it looks to expand its proprietary content into slots. Using Yggdrasil’s framework also gives Eeze access to its wider distribution network.

The first games are expected towards the end of the year, with the partnership ultimately targeting a release cadence of two games per month. For Curwen, Eeze demonstrates the demand among established gaming businesses for greater ownership of their content strategy without the cost and complexity of creating a conventional development operation.

The implications could extend well beyond companies already established in other areas of gaming.
