Happiness

"Happiness" is an in-game mechanic that indicates how friendly the Pokémon is to the owner, from a scale of 0 to 255. A Pokémon's Happiness is seen as a percentage in its summary, on the party screen, or when hovering over it when viewing Fields.

Note: Happiness is not the same thing as Affection. If a Pokémon states they need max Affection to evolve please visit the Affection wiki page.

Effects

Evolution

There are Pokémon that require a certain amount of Happiness to evolve.

There are currently 21 Pokémon that evolve from having high Happiness. In order to evolve, the Pokémon must have a Happiness of 220 or more.

There are currently 2 Pokémon that evolve from having 0 Happiness (also known as Unhappiness). Due to rounding, the Happiness percentage may show 0% even when the Pokémon has more Happiness.

Note: When this happens the Pokemon will not evolve yet. Wait a while longer and it will evolve once the percentage is truly 0%.

Breeding

Happiness is factored into the breeding percentage of two Pokémon that are left in the Daycare. The higher the happiness the higher the breeding percentage will be. This means a higher chance of the Pokémon pair producing an egg.

Raising Happiness

Fields

If a Pokémon is put into a field that matches or is super effective against their type, they will gain Happiness. For example, Espeon, a Psychic type, will like the Psychic, Bug, Ghost, and Dark fields. Since Espeon matches the Psychic type, its Happiness will increase faster in a Psychic field than in a Bug, Ghost, or Dark field.

Dual Types
		Type 2
		Match	Super Effective	Neutral	Not Very Effective	No Effect
Type 1
	Match	+8/hr	+6/hr	+4/hr	+2/hr	-8/hr
	Super Effective		+4/hr	+2/hr	0/hr
	Neutral	+4/hr	+2/hr	0/hr	-2/hr
	Not Very Effective	+2/hr	0/hr	-2/hr	-4/hr
	No Effect	-8/hr

Exceptions:

• Hisuian Zorua is a Normal and Ghost-type Pokemon. These types do not have any effect on each other which means that neither of its matching field types will raise its happiness.
  • The only Field Type that will raise a Hisuian Zorua's happiness is a Dark Type Field. The reason is that the Dark type is the only type that is super effective against Ghost types and has a normal effect on Normal types.

Pokémon that are busy, such as Pokémon in the DayCare, will not gain or lose happiness from fields. If a Pokémon has been in a field for awhile and not gaining any happiness try moving the Pokémon out of the field then back in. This should allow the Pokémon to start gaining happiness.

Consumables

Certain Consumables can be used to raise happiness. These consumables raise the happiness value by a certain number. E.G. A Sweet Heart will raise a Pokémon with a value of 70 to 90. This is approximately a 7.8% raise to the happiness percentage.

Note: These consumables are obtainable by trading with other users or during certain events.

• Cookies were obtainable from the Valentine's Event and Advent Calendar.
  • Boosts Happiness by 50 and boosts Experience by 50% of the Pokémon's current level.
• Sweet Hearts were obtainable from the Valentine's Event and Advent Calendar.
  • Boosts Happiness by 20.
• Easter Eggs were obtainable from the Easter Event.
  • Boosts Happiness by 20.
• Lovely Soups were obtainable from the 2019 Valentine's Event.
  • Boosts Happiness by 50.

Trading

Trading resets a Pokémon's Happiness to 70. This can be used to restore a Pokémon's low Happiness, but can also lower a Pokémon's Happiness if it is higher than 70.

Lowering Happiness

Fields

If a Pokémon is put into a field that has zero effect or is not very effective against their type, they will lose Happiness. For example, Umbreon, a Dark type, will dislike the Psychic and Ghost fields. Since Umbreon completely resists the Psychic type, its Happiness will decrease faster in a Psychic field than in a Ghost field.

Type immunity (aka zero effect) overrides all other compatibility checks. For example, Stunfisk, despite being ground/electric, loses happiness in an electric field due to electric types having zero effect against ground types. Hisuian Zorua is a Normal/Ghost type meaning that if placed in either of its type's fields, it loses happiness due to both Normal and Ghost being immune to each other.

Pokémon that are busy, such as Pokémon in the DayCare, will not gain or lose happiness from fields.

Gigaremo

Use of the Red Gigaremo will reduce the happiness of both Pokémon in the Daycare while increasing the number of eggs bred. If Happiness runs low, the pair's breeding rate is decreased until their Happiness is restored. At 0 Happiness, Pokémon will refuse to produce eggs.
