Rainbow Princess

Rainbow Princess by Hacksaw is a cluster-pay video slot played on a 6×5 grid where wins form when at least five matching symbols connect horizontally or vertically. It is set in an anime-fantasy theme with pastel skies, dreamy clouds, gems, crowns and magical motifs, all centered around the titular rainbow-clad princess. One of its main features is Super Cascades: after a winning cluster, those symbols are removed and new ones drop down, allowing chain reactions of wins. Another core mechanic is Magic Frame Multipliers, which can land in random grid positions when there is at least one winning cluster. These frames carry values from 2× up to 100×, activate when involved in a win, and double in value in subsequent cascades in the same spin. Aurora Gems may also appear during cascades and, when activated, multiply all existing Magic Frame Multipliers currently on the grid; only one Aurora Gem can be active at a time. The game includes three distinct Free Spins bonus rounds: Tiara Treasure (triggered by three scatters), Make It Rainbow (four scatters), and Throne of Starlight (five scatters), each starting with ten free spins. Tiara Treasure grants sticky progressive Magic Frame Multipliers that persist through the free spins; Make It Rainbow adds a Rainbow Rush Bar that fills with winning clusters and, once full, places wilds onto the grid; Throne of Starlight begins with every grid position having a sticky progressive Magic Frame Multiplier of at least 4×. Rainbow Princess also offers a Feature Buy option letting players directly purchase access to BonusHunt FeatureSpins, Magic Mode FeatureSpins, or specific Free Spins rounds rather than triggering them via scatters.
