Octo Attack
Octo Attack is a grid-based slot from Hacksaw Gaming, built around cluster pays and fast-paced features. Instead of traditional paylines, wins land when matching symbol groups connect on the grid, with cascading (avalanche) wins keeping the action going as new symbols drop in.
How Octo Attack works
The game uses a Grid & Cluster Pays system: you’re aiming for clusters of matching symbols rather than line combinations. When a cluster wins, it disappears and triggers Avalanche / Cascading wins, giving you a chance to chain multiple payouts in a single spin.
Key features and symbols
Octo Attack includes classic slot mechanics like Wild symbols to help complete winning clusters, plus Scatter symbols that can unlock feature rounds. It also uses Symbol Swap-style moments where symbols can change to create or extend winning clusters, adding extra unpredictability to the cascades.
Free Spins and Bonus Buy
Free Spins are one of the main highlights, activated via Scatter symbols (as is typical for this type of feature). For players who prefer quicker access to the bonus action, Octo Attack also offers a Bonus Buy option, letting you purchase entry into the feature round directly where available.
Volatility
Octo Attack is tagged as Medium Volatility, meaning it generally balances the potential for frequent smaller hits with the possibility of larger wins through connected clusters and long cascading sequences.
