What is Rainbow Reels?
For a second year, the Las Vegas Convention & Visitors Authority (LVCVA) is organizing the city-wide “Vegas 5-Day Sale.” Officially running from today (Sept. 22) through Saturday (Sept. 26), the event for 2026 includes more than 180 limited-time offerings.
Caesars is offering rooms at its Las Vegas properties discounted by up to 60% for stays through March 2027. The Caesars Palace operator is extending the five-day promotion to 9 am PT on Tuesday, Sept. 29.
Caesars is additionally offering $50 tickets for Josh Groban and Tim McGraw, $30 seats for Jeff Dunham, and 20-25% discounts on the High Roller Observation Wheel, Fly LINQ Zipline, and Eiffel Tower Viewing Deck.
How to play Rainbow Reels
In practice, the colored fireballs feed matching pots that shape how the Power Spins bonus plays out. Trigger the bonus game via the green fireball and the feature runs with the Expand enhancement; any green scatters that land can unlock up to three additional rows. The Collect and Multiplier variants offer alternative routes into the same bonus framework.
The significance here isn’t the individual modifiers. It’s the reuse pattern. Blueprint is carrying a differentiator across the franchise, reinforcing a recognizable identity rather than asking returning players to learn a new core engine.
The pattern reflects a wider supplier tactic: building recurring mechanical families so a proven feature can be redeployed across multiple titles. That approach lowers development risk and reduces the familiarity barrier for players. For operators, it typically means a steady supply of new content that behaves in predictable, sellable ways.
About Rainbow Reels
It has been a challenging few years for Entain, having cycled through four CEOs in short succession. In November 2023 Entain agreed to pay a financial penalty totalling £585 million, plus a £20 million charitable donation and £10 million in Crown Prosecution Service (CPS) and HMRC costs. This related to a bribery case initiated by the CPS into the company’s historic operations in Turkey.
Troubles continued as it faced declining growth within its digital business. Reports of failed integrations amid a frenzy of acquisitions further dampened Entain’s reputation and the operator subsequently committed to a major turnaround effort to cut costs and return its digital business to growth.
Efforts to update its legacy tech were also set in motion, and short-lived CEO Gavin Isaacs told iGB at ICE in January 2025 that his biggest challenge in the role was to modernise its core platform.
