5. Getting caught by the shepherd or catching a killer goat ends the game

Field Layout

• Dimensions: 960×540 pixels
• Goats: 8 standard goats with individual multipliers
• Shepherd: 1 AI-controlled shepherd
• Fox: Player-controlled character
• Tick Rate: 60Hz server-authoritative

Goat Catches

Each goat has a pre-determined multiplier assigned at session start:

payout = betAmount × goatMultiplier

Multipliers are drawn from the provably fair RNG and vary by RTP variant.

Killer Goat

One goat in each session is secretly designated as a killer goat:

• Catching the killer goat immediately ends the game
• The player loses any uncollected winnings for that round
• Killer goat is visually identical to other goats (no way to distinguish)
• Killer goat probability varies by RTP variant

Shepherd AI

The shepherd has three behavioral states:

State	Description	Fox Detection Range
sleeping	Stationary, does not detect fox	0 (inactive)
alert	Stationary but watches for movement	120px
patrolling	Moves along a patrol path	180px

The shepherd transitions between states based on the game timer and player actions:

• Starts in alert state
• Transitions to patrolling after the first goat is caught
• May enter sleeping during special rounds

Special Round

Triggered randomly (probability varies by RTP variant):

• +6 bonus goats added to the field
• Shepherd enters sleeping state
• Duration: 10 seconds
• Higher-value multipliers on bonus goats

move(dx, dy)

Move the fox by a delta vector. Rate-limited to 60Hz.

  "payload": {
    "action": "move",
    "dx": 5.0,
