Slot Summary

Marking every cleared position creates the chance for a later symbol replacement to cover much of the board at once. Octo Attack names that interaction Tenta-Grab: Hacksaw Gaming's octopus selects a symbol and places it across the Ink Stains left by earlier cluster wins. Cascades therefore prepare the next intervention instead of simply extending the current payout. Its 94.26% RTP and Medium volatility make those transformations the key source of variation on the 6x5 grid.

How It Plays

Matching symbols form Cluster Pays across the 6x5 Grid. Winning groups disappear through Cascading drops, leaving Ink Stains on the cleared positions.

Otto can then activate Tenta-Grab, choosing one paying symbol or Wild and transforming every stained position before the board is evaluated again.

Theme & Atmosphere

The Sea setting treats its octopus as a disruptive Monster rather than background decoration, giving each tentacle event a clear connection to the rules.

Cartoon and Graffiti themes soften the Apocalypse imagery, while Fish and Shark figures keep the crowded underwater Grid readable during rapid replacements.

Features & Win Potential

Transforming Symbols and Symbol Swap effects change marked areas at once, while Random Wilds or Additional Wilds can improve the resulting cluster arrangement.

Increasing Multipliers appear in the stronger Free Spins mode, making persistent marked positions more consequential each time another replacement crosses the Grid.

Bonus & Free Spins

Landing 3 Free Spins Scatter symbols awards 8 Free Spins in the first feature, where Ink Stains remain until Tenta-Grab consumes them.

Landing 4 Scatter symbols opens the stronger 8-spin feature. Its Ink Stains persist for the complete round, and Wild Multipliers can affect transformed clusters.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (94.26%), with wins capped at its top multiplier (10,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
