Online instant win games provider IWG has launched its new Rollover Jackpots product with the GVC Holdings-owned bwin brand.

bwin becomes the first operator to launch the supplier's jackpot mechanic, which can be applied to any IWG game and offers prizes starting from £5m and up to £25m.

The deal expands on GVC's existing relationship with IWG, which has seen a number of instant win games launched on its brands, including Cash Buster and Slingo.

"IWG's games have proved immensely popular with our customers and we're confident the addition of Rollover Jackpots will significantly enhance the user experience," said GVC chief product officer Liron Snir. "Jackpots are a sure-fire way to grab players' attention and with a potential £25m up for grabs, it's sure to have massive appeal.

"What's great about the IWG jackpot mechanic is that we don't have to share the liquidity with others, something that is very common with networked jackpots," he added.

IWG chief executive Rhydian Fisher said he was "thrilled" to have launched the jackpot solution with GVC, having built up a strong relationship with the operator over the past year.

"Rollover Jackpots is the first product to offer such massive prizes in the online instant win space, introducing another layer of excitement to our already popular games with the addition of a giant prize pot," he explained.
