Increase your legendary hatch rate with these proven techniques.
Save 20+ eggs and hatch them consecutively. Legendary rates seem higher when hatching in bulk (anecdotal but widely reported).
Feed your pet a speed potion (from hospital) before hatching – some players believe it influences RNG.
Weekend events often have 2x legendary chance. Check the event board in the nursery.
Less lag = faster hatching. Use a private server if available.
