Origin Horses
Strategic Value of Origin Horses
Origin Horses are not only rarer and more powerful, but they also serve as genetic anchors for the Planet Horse economy. With limited breeding across generations, Origin NFTs ensure controlled population growth and long-term value.
With only 2,202 Origin Horses available in the inaugural drop, owning one means owning a piece of the foundation of Planet Horse. These horses are your gateway to earning, evolving, and expanding within a thriving and competitive ecosystem.
Breeding Foundations
In Planet Horse, Origin Horses serve as the cornerstone of ecosystem expansion through a robust breeding system. These special NFT horses possess enhanced breeding capabilities, allowing them to create new generations of race-ready offspring. Their breeding count is determined by rarity, ensuring higher-rarity Origin Horses can be leveraged more strategically to expand your stable.

Offspring Limitations
Offspring horses — those bred from Origin Horses — have limited breeding potential, with a randomized breeding count between 0 and 3 over their lifetime.
Breeding Costs (Dynamic Model)
Breeding uses a dynamic formula that adapts to rarity, the oracle price of $PHORSE, and each parent’s breeding history. This ensures long-term sustainability of the economy while protecting the value of Origin Horses.
Key Rules:
Base cost is defined in USD depending on the lowest rarity parent:
Common → $10
Uncommon → $15
Rare → $20
Epic → $25
Legendary → $30
Mythic → $40
The parent with the highest breed count (
maxCurrentBreeds) is used to calculate breeding tax.Each additional breed on that parent adds +$5 USD to the base.
Formulas
PHORSE = ((baseUsd + (maxCurrentBreeds × 5)) ÷ usdPrice) + (maxCurrentBreeds × usdPrice)
RON = (maxCurrentBreeds + 1) * 1.8Where:
usdPrice= oracle price of $PHORSE in USD.maxCurrentBreeds= the higher breed count between the two parents.breedBaseRon= predefined curve that increases with each breeding attempt.

Breeding Chances
To breed, you must pair one Male and one Female horse. Horses of any rarity can be matched together.
However, the rarity of the offspring is determined by the lower rarity parent. For example, breeding a Rare horse with a Legendary one will follow the Rare breeding table.
The offspring rarity chances are defined per rarity tier. Each breeding table specifies the chance to produce a horse of a certain rarity. The array format is as follows:
[Common (%), Uncommon (%), Rare (%), Epic (%), Legendary (%), Mythic (%)]
Common
[73, 21, 5, 1, 0, 0]
Uncommon
[30, 55, 13, 2, 0, 0]
Rare
[5, 15, 65, 12, 3, 0]
Epic
[0, 4, 25, 63, 6, 2]
Legendary
[0, 1, 6, 30, 56, 7]
Mythic
[0, 0, 1, 8, 30, 61]
Breeding Status Calculation & Gene Splicing
Offspring Status Calculation
New offspring inherit one base statuses from each of their parents. Base stats refer to a horse’s stats at level 1, excluding any gains from leveling. Consider the following example:
Base Power
1
Base Sprint
2
Base Speed
2
Base Power
3
Base Sprint
2
Base Speed
1
The resulting offspring will have:
Base Power
3 (Inherited from parent two)
Base Sprint
1 (Random inside its rarity range)
Base Speed
2 (Inherited from parent one)
Gene Splicing
Gene splicing is the act of burning an NFT horse and using its genes to create a new improved one. When a horse is burned, the user receives a level-up Voucher (Each horse in existence can use only 1 level-up voucher ever!), plus one of the following gene items:
Power Genes: Adds +3 to a horse’s base Power stat during breeding.
Sprint Genes: Adds +3 to a horse’s base Sprint stat during breeding.
Speed Genes: Adds +3 to a horse’s base Speed stat during breeding.
These gene items can then be applied to other horses during breeding to further boost inheritance beyond parent stats and make sure you inherit the target stats based on the used genes!
Example: Breeding with Gene Items
Using the previous example, assume Parent One is given Power Genes (+3 Power) and Parent Two is given Speed Genes (+3 Speed) before breeding:
Base Power
1 + 3 = 4
Base Sprint
2
Base Speed
2
Base Power
3
Base Sprint
2
Base Speed
1 + 3 = 4
Offspring now inherits the highest boosted stats:
Base Power
4 (Inherited from parent one)
Base Sprint
2 (Random inside its rarity range)
Base Speed
4 (Inherited from parent two)
This demonstrates how gene splicing can significantly enhance breeding outcomes by boosting specific base stats beyond the parents’ original values.
Rarity & Stat Influence
Each horse in Planet Horse has three core stats: Power, Sprint, and Speed. These stats, along with a horse’s maximum level cap and growth potential, are determined by its rarity.

Higher rarities also possess greater GROWTH POTENTIAL, a hidden trait that determines how much a horse’s stats increase per level.
Comparison (Common Horse Growth vs Epic Horse Growth)
In this example we see the difference between a Common horse versus an Epic horse growth in terms of status.

At maximum level (30), the total cost reaches 126,000 $PHORSE and 624 medals. Higher levels demand increasing investment, rewarding long-term dedication and smart resource management.
Leveling up a horse does more than just improve its energy—it boosts stats using the following formula:
new_stat = old_stat + 2 * growth_potentialGrowth potential is a hidden trait rolled during level-up, and higher-rarity horses consistently roll higher values.
Medals are also required to level up. Horses earn 1 medal each time they finish 1st, 2nd, or 3rd in a race.
