Getting Started

To play, you'll need
• a supported wallet - we recommend XCP Wallet
• BATTLECORN token
• some fighters

First, connect your wallet. By doing so, you are giving this website (read-only) permission to verify that you control the bitcoin address that is battling. It's a crypto thing. Once you verify an address, we check for the BATTLECORN token, which is required to play. It allows the holder to play 3 battles per day, just like the original game did. Next we check to see which fighters you have - you need to have at least one to battle.

The battle starts when you choose an enemy farm to attack. There are rounds of attack and defend, until someone loses all fighters. In each round an attack takes place and Some(damage) is done, or maybe None, to the defender. After you attack, expect a vigorous counterattack!

Fighters

Here are the relative attack, defense, and health strengths of the fighters:

Leaderboard

The leaderboard ranks farms by various metrics. The default is a ranking system we use called an Elo Rating system. Here are the main reasons we replaced the original ranking by wins leaderboard:

Raw Wins
• favors grinders
• punishes new players
• top spot becomes impossible to catch

Elo Ratings
• beating strong farms matters more
• upset victories feel meaningful
• rankings self-balance naturally

Damage Scoring

When an attacker and defender have been chosen and the player clicks the button to attack or defend, the defender takes damage. How much damage is based on the fighters' attack and defense levels, along with some element of chance.

The difference between attack and defense strengths is varied by a random amount between -20 and +25. Non-zero damage is the result in 90% of cases. The other 10% of the time, damage is either doubled or tripled. Here is the code snippet that shows the calculation:

 	let base = attacker_attack - defender_defense;
	let variance: i64 = rng.random_range(-20..=25);
	let mut dmg: i64 = base + variance;

	// critical damage chances: 10% 
	let crit = rng.random_bool(0.1);
	let crit2 = rng.random_bool(0.25);

	if crit {			//  for 10% of these, at least 2x
		if crit2 {		//  1/4 of those will be 3x
			dmg *= 3;
		} else {
			dmg *= 2;
		}
	}
	// never heal the enemy accidentally
	let dmg = dmg.max(0);
