Purrrminator Dream Drop

Purrrminator Dream Drop by Relaxgaming is a video slot featuring a 6-reel by 4-row layout that uses a connected ways win mechanic rather than traditional paylines. The theme is animal-based with a twist: a heroic cat versus street dogs in a dystopian, gritty urban setting, rendered in sharp, cartoonish visuals and a humorous tone. One of its core features is the Reverse Avalanche: when you form a win, those symbols stay locked in place while all others (except bonus symbols) are removed and replaced, giving opportunities for additional matching symbols to drop in. Expanding Symbols also appear during drops, marked with arrows to indicate whether they will grow upward or downward in a reel, increasing their potential. Free Spins are triggered by landing 3 or more Scatter (alarm clock / bonus) symbols during a single Reverse Avalanche; depending on whether you get 3, 4 or 5 scatters, you can receive various numbers of free spins. In Free Spins the grid is expanded to 6 reels and 5 rows, and all base game mechanics—including Reverse Avalanche and Expanding Symbols—apply. There is also a Dream Drop Jackpot: a randomly triggered bonus mode offering a chance to win one of several progressive jackpots. If you prefer, there is a Feature Buy option allowing you to directly purchase the Free Spins bonus for a fixed multiplier of your bet. Max win potential can go up to around 5,000 times the bet plus whatever the Dream Drop Jackpot awards.
