🐑Moonsheep Cannon

Shoot the sheep

Moonsheep Cannon is a collaborative game between Witty and @moonsheepverse, where players bet, aim, and launch sheep across chaotic, cartoonish landscapes filled with mushrooms, aliens, and volcanoes. Every shot is a mix of skill, timing, and luck, and every meter your sheep travels increases your payout.

🎯 How to Play

1. Set your launch angle using the up or down buttons (between 15° – 75°).

2. Choose your bet amount.

3. Press Launch or hit the spacebar to fire your sheep.

4. Watch it fly. Distance and interactions with objects determine your reward.

For every 100 m traveled, you earn 1× your bet. For example, reaching 330 m gives a 3.3× return.

⚡ Terrain Bonuses & Hazards

• UFOs, mushrooms, volcanoes, and aliens boost flight distance or add bonus multipliers.

• Aliens come in three types:

  • 🟡 Gold Alien: +10× bonus

  • 🟢 Green Alien: +3× bonus

  • 🔴 Red Alien: +0.3× bonus

• Flags or batteries instantly end the run. Hitting them means you lose your bet.

🧠 Fairness & Randomness

Each run is generated deterministically from pre-simulated terrain data and a random seed derived from a cryptographic hash. For each possible angle, several thousand runs are pre-computed under different seed values, each describing a unique terrain layout.

When a player launches, a random seed is selected by hashing the submitted signature, ensuring that results cannot be predicted or manipulated.

const resultSources: any = {}; // sheep-cannon-data-casino-chaos-gold.json

export async function playSheepCannon(angle: number, signature: string): Promise<any> {
  if (!Number.isInteger(angle) || angle < 15 || angle > 75) {
    throw new Error('Invalid angle');
  }

  const signatureHash = keccak256(toBytes(signature));
  const hashBytes = toBytes(signatureHash);
  let randomValue = 0;
  for (let i = 0; i < 4; i++) {
    randomValue = (randomValue << 8) + hashBytes[i];
  }
  const randomIndex = Math.abs(randomValue) % resultSources.length;
  const result = resultSources[randomIndex];
  return result;
}

This function converts the player’s signature into a pseudo-random index that selects one of the pre-simulated terrains from sheep-cannon-data-casino-chaos-gold-2.json. Because the data and code are public, anyone can verify that every launch follows deterministic logic.

📜 Verification & Data Access

All simulated map data used for Moonsheep Cannon outcomes is publicly available on IPFS for transparency and independent verification. You can inspect or download the dataset below to review the pre-simulated results, expected payouts, and terrain seeds used by the game.

This file contains the complete set of simulated results for every angle under multiple seed values. Each entry corresponds to the deterministic outcomes referenced by the randomness function, ensuring that every launch is verifiable and reproducible using the open-source code provided above.

💰 RTP and Risk

• The Return to Player (RTP) varies slightly by launch angle, typically between 96.66 ~ 96.74 %.

• Across all angles combined, the overall RTP is 96.69 %.

• Lower angles carry higher risk and higher potential payout.

• Higher angles provide more consistent, lower-variance returns.
