Swing For Eggs Hatch Alert Tool
Start a countdown the moment an egg begins hatching, and get an alert in this browser tab when the timer ends.
What This Tool Does
Waiting on a Colossal Egg or a Secret Egg that still has hours to run? Start the countdown here and use the waiting time to farm or train elsewhere. The alert fires in this tab, so the game does not have to be on screen.
It times a timer you start, not an event in your server. The tool cannot see your egg, the hatch screen or a Secret egg announcement, and it stops if you close the tab, reload the page or let the device sleep.
Configure Your Alert
Starting the timer asks for notification permission once. Declining still gives the on-screen alert.
Pick a preset or your own minutes, then start the countdown the moment the egg begins hatching. Nothing is sent anywhere: the timer runs in this tab.
This is a browser timer, not a connection to the game. It cannot see your server, the hatch screen, or a Secret egg announcement. A closed tab, a sleeping device or a reloaded page stops the alert.
Why Set Alerts Instead of Watching?
Hatch Waits Run From Seconds to Hours
The readings in the egg database start at 1m 39s on a base egg, passed 13m on a placed Colossal egg, and reached 2h 05m on a Secret one. Sitting in front of that screen is the expensive part, and a timer lets you train speed or farm another egg while it runs.
A Timer Cannot Predict a Spawn
Secret egg spawns are announced when they happen, and no published schedule or interval exists for them. An alert here can only time a countdown you started — it cannot tell you when a spawn or a night reset will happen in your server.
Night Resets Refill Nests
Per the official description, all nests reset every night. Since day/night cycles run locally per server, tracking your own server's reset interval with the Night Reset Timer and pairing it with an alert keeps you ahead of other players.
