Rainbow Ray

Rainbow Ray is a video slot from Endorphina that features a layout with 6 reels and 5 rows, as well as a "pay anywhere" mechanic where symbols act as scatters - they can appear anywhere on the reels as long as enough matching symbols are displayed. The theme is inspired by Irish folklore, with leprechauns, rainbows, four-leaf clovers, and gold mines hidden among lush mountains and meadows. One of the central features is the cascading reels: when a winning set of symbols is formed, those symbols disappear, new ones fall in, and you can achieve chain reactions of wins. Another major feature is the Free Games mode, which is activated by getting four or more Leprechaun Bonus scatter symbols, granting 10 free spins. During Free Games, you can reactivate extra spins if enough Bonus symbols appear again. Multipliers ranging from x2 up to x100 can land during Free Games, but they remain inactive until the end of each winning cascade; then all collected multipliers are summed up and applied to the win. A Magic Clover symbol only appears during Free Games; when it appears, it blasts away all standard symbols on the same row and reel (excluding bonus and multiplier symbols) and triggers additional cascades. Rainbow Ray also includes a Risk Game feature (sometimes called gamble) that allows players to try to double wins up to a certain number of times. There is a Bonus Pop / Bonus Buy option in many markets, allowing players to directly purchase entry to the free spins round instead of waiting for it to be triggered.

You can play it for real money.
