Octo Attack is an online slot that was developed by Hacksaw Gaming and released in 2024. The game focuses on the evil Otto the Octopus as he unleashes an attack on a city.
The Octo Attack slot is set in a busy black-and-white city, as a colourful blue Otto stands beside the reels. Symbols in the game include wild icons, sharks, ice cream, mushrooms, beer cans, fish, hearts, boxes, message bubbles, bolts, fish hooks, free spin scatters, Otto eyes, ink stains, and more.
The Octo Attack slot uses a 6×5 grid layout with a cluster pays mechanic that requires you to form clusters of five or more icons to make wins. You’ll need to bet between £0.10 and £100 per spin, and you’re given a chance to win up to 10,000x your bet, which is huge.
The highest-paying symbol in the Octo Attack slot is the wild icons, which pay £60,000 for a cluster of 26 to 29 symbols and a maximum of £100,000 for a cluster of 30 icons. After this, the shark pays £50,000, the ice cream and mushroom each pay £25,000, beer cans and fish pay £15,000, and the remaining symbols all pay £10,000.
The Octo Attack slot comes with a return to player (RTP) rate of 96.27%, which is around the average for most video slots. The game also comes with medium volatility, so you can expect to make both big and small wins when playing.
The Octo Attack slot comes with wild icons that substitute for all symbols to help you make more wins. Wild icons can also appear with multiplier values of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, or 10x.
Whenever winning combinations are made, the winning symbols are removed and new icons drop to fill in gaps. Winning positions are marked with ink stains, which are only removed from the grid when they’ve been used by the tenta-grab mechanic.
The eye of Otto triggers the tenta-grab mechanic when it lands on the grid with ink stains. When activated, the tenta-grab mechanic randomly grabs one symbol from the grid and replaces all ink stains with the chosen icon.
Landing three normal free spin scatter icons at the same time during the base game triggers the free spins mode, with the total number of spins awarded equal to the number of triggering icons. During the feature, ink stains are not removed from the grid until they are grabbed. Landing additional free spin scatter icons awards more spins.
Landing three epic free spin scatter icons awards the give me eight free spins mode. It functions similarly, but the tenta-grab can only grab wild or wild multiplier icons.
