Summer Rush Slot by Fazi

Land 3 or more of the gold VIP BONUS diamonds and the free games kick off, but the number you trigger with sets the length: 3 diamonds for 7 spins, 4 for 10, 5 for 15. The twist is what happens before the first spin. The game picks one regular symbol at random and turns it into an extra wild for the whole feature, so every copy of that symbol on the reels chips in to complete wins alongside the normal wild symbol. Get a frequently-landing symbol and the round can pour. Here's the honest catch, though: the chosen symbol tends to be one of the lower payers, so a lot of the time you're getting help on combinations that weren't worth much to begin with. When it picks a richer symbol, that's when the free games actually deliver.

The setting is a glossy beach-resort holiday: turquoise sea behind the reels, palm trees and sun loungers along a jetty, all lit in bright postcard colours. The symbols match the fantasy. A yellow sports car, a white yacht, a blonde woman in oversized sunglasses, and a row of vivid cocktails (an orange one, a green mojito, a red berry mix), with a strawberry and cherries filling out the bottom of the paytable. It's good-looking, if a bit by-the-numbers, the VIP-summer theme has been done plenty of times.

Base game runs the standard wild that stands in for the paying symbols, no expanding or multiplier behaviour, just a clean substitute. Three mystery progressives (Gold, Diamond, Platinum) sit underneath, each fed by a slice of every bet and dropping at a hidden random point, so betting higher shortens the odds on the progressive jackpots without giving you anything to aim at. After any win you can run a red-or-black double-up, guessing the colour to double your money over and over until you miss or hit the 50,000 win ceiling. Pick the chosen wild well in the free games and this one has a real ceiling at 1,043x; pick a dud symbol and you're mostly watching cocktails line up for small change.
