EGG AND PET RARITY

There are many different pets going from the funniest to the most majestic. Each pet gives different boosts depending on its rarity, level and rank. They boost critical rate and give a money multiplier.

after a short animation showing what you got,

your pet will be added to the inventory that is accessible through the dropdown menu, where you can equip your pet up to a maximum of three pets at once.*

Upgrade your pet and rank them up! At first your pet will reach its maximum power at level 10, but if you level up two pets of the same type to their max level you can then merge them to create a new pet of a higher rank with a new, bigger level cap.*

Now a bit of maths

pet upgrade cost

public int UpgradeCost(PetInstance pet) {     if (pet == null)     {         return 0;     }      int rarityValue = getRarity(pet);      float rarityMult = 1f + rarityValue * 0.60f;     float rankMult = 1f + (Mathf.Max(1, pet.rank) - 1) * 0.35f;     float lvlGrowth = Mathf.Pow(Mathf.Max(1, pet.Petlvl), 1.18f);      petData petData = GetPetData(pet);      float baseCost = 100f;      finalCost = Mathf.RoundToInt(         baseCost * rarityMult * rankMult * lvlGrowth / 10f     ) * 10;      pet.currentUPcost = finalCost;      return finalCost; }

Upgrade costs start from 100 coins and increases by 60% for each rarity(common doesn't increase base cost), then another 35% for each rank, going from 1 to 5. Lastly, current pet level is also used to calculate upgrade cost, this cost is then rounded to the nearest multiple of 10.

Level up experience scaling

if (data.xp >= data.xpMax) {     data.xp -= data.xpMax;     data.lvl += 1;     lvlup = true;      Unlock();      data.xpMax = Mathf.RoundToInt(35f * Mathf.Pow(data.lvl, 1.65f));      StartCoroutine(LevelUpAnimation()); }

 Required experience scales with player level to 1,65(value found with various balancing tests) multiplied by a coefficient of 35(also obtained by testing), and rounded to the nearest integer.
