The head and knight must meet the entry condition
The feature starts when a snakehead appears on reel one and a Knight appears on any reel. The position of the head matters: the rule is more precise than “land two special symbols anywhere.”
Once inside the feature, a Knight appears on every spin. Before the next spin, the snake moves toward that target. Reaching it consumes the knight, lengthens the body and allows the sequence to continue. The Wild body’s growth is therefore linked to successful catches, not simply to elapsed spins.
The shortest route allows at most one turn
The game chooses the shortest permitted path to the knight, using no more than one turn. The snake’s initial facing direction is disregarded for this calculation. This can make the animation look unlike a manually controlled arcade snake that must keep moving in its current direction.
For a target two columns to the right and one row above, the two basic shortest routes are horizontal-then-vertical and vertical-then-horizontal. The game checks the permitted alternatives rather than allowing the player to draw a more elaborate detour. This example explains the path rule; it does not forecast a particular next Knight position.
An available route is chosen by the game
If one of the two routes reaches the knight, the snake takes a valid route. If both reach it, the game chooses between them randomly. If neither does, the snake collides with itself and no further spins are awarded.
The rule does not authorize a longer path with several bends merely because a human viewer can see one. That distinction answers a common “why did it crash?” question. The feature is constrained by its documented movement system, not by every route that could be drawn through the grid.
A larger body changes two things at once
Growth can place more Wild coverage on the field, while also creating more occupied positions for the next movement check. The same progress that makes the snake visually impressive can restrict its later route.
That is the design’s strongest tension. It also means length alone is not enough to estimate the remaining feature duration. The next Knight position and the available permitted paths still matter. No probability of survival is inferred from a screenshot of the body.
Filling reels two to five ends the feature successfully
The documented completion condition is filling all positions on reels two through five with the snake. This ends the feature and awards an additional 1,000× stake. It is a distinct completion prize, not the same as the ordinary symbol payout table.
At a €0.20 base stake, the additional 1,000× award would be €200. At €0.50 it would be €500. Those calculations illustrate the unit; they do not claim that a particular session reached the condition or that buying the feature guarantees it.
Completion and collision are different endings
A collision ends the feature because no permitted path reaches the knight. Completing the required field also ends it, but with the additional prize. Describing every ending as “the snake dies” would hide the important difference between those outcomes.
The feature does not start with a published fixed batch such as ten spins in the checked rules. It continues through catches until one of its ending conditions occurs. The Free Spins category explains why games grouped under that label can have quite different continuation rules.
A purchase enters the feature, not the completion state
The original has a Buy Feature in supported versions. Its help says a purchase guarantees entry to the snake feature. It does not say that it fills the body, guarantees a specific length or supplies the 1,000× completion award.
The public help fills the price and purchase RTP from the active configuration, so this review does not invent a universal cost. Read the confirmation screen and compare the actual charge with the eventual credited amount. The Bonus Buy guide shows how a large base-stake multiplier can still represent a loss relative to the entry price.
