Octo Attack

Octo Attack by Hacksaw Gaming features a 6-reel, 5-row grid using a cluster pays mechanic, where wins form from five or more matching symbols connected horizontally or vertically. After each win, symbols are removed and replaced by cascading new ones, leaving Ink Stains in their positions that persist until activated by the Eye of Otto symbol, which triggers the Tenta-Grab mechanic to randomly select and replace all Ink Stains with one symbol type, including potentially wilds, wild multipliers up to 10x, or free spin scatters. Symbols include low-paying hooks, bolts, and hearts in black and grey, contrasted by colorful high-payers like fish, ice cream, and sharks. Free spins activate via three or more normal FS scatters for 'Eighth Arm Is the Charm,' where Ink Stains remain between spins and grant extra spins every three scatters, or epic yellow FS scatters for 'Give Me Eight,' restricting Tenta-Grab to wilds and multipliers. Bonus buy options include BonusHunt (3x bet for higher bonus chance), Tentacular FeatureSpins (50x for guaranteed win and Eye of Otto), Eighth Arm Is the Charm (100x), and Give Me Eight (300x). The visual style employs a monochrome ocean backdrop with splashes of color on premium symbols and dynamic octopus animations during Tenta-Grab, distinguishing it through persistent Ink Stains and versatile symbol substitution that can chain massive clusters or bonus triggers.
