How to play Rainbow Princess

The strategic detail is what happens when features overlap. When two feature types activate together, Super Charged Free Spins combines both sets of mechanics, and when all three activate, Mega Stampede Free Spins brings the six-row grid, Thunder Bison and Multiplier Wilds into the same seven spins.

It lets a single title behave like several different bonus games

That combinatorial structure is the real product idea. It lets a single title behave like several different bonus games depending on which crystals land. An optional setting layers on top: GO Ultra doubles every Free Spins award from seven to fourteen spins.

What is Rainbow Princess?

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

The institutional layer is largely invisible to customers presented with a P2P proposition. Retail users may technically trade against one another, but the depth required by a mass-market product cannot be supplied by occasional customers alone. Professional firms must be prepared to quote continuously and commit substantial capital.

Marantelli says the London-based White Swan is a significant market maker on several secondary exchanges, accounting for as much as 40% of activity on some platforms. Its particular focus is the RFQ, parlay market.

About Rainbow Princess

On Monday, the Gambling Regulators European Forum (GREF) announced a reshuffle of its board following the departure of two long-standing members and the appointment of two new officers.

GREF is a cooperative network bringing together national gambling regulators across Europe and beyond to facilitate dialogue, exchange information and share best practice on regulatory strategies. 

Tim Miller, who resigned from the UK Gambling Commission earlier this year, has stepped down from the GREF board and has relinquished his role as treasurer.
