Summer Break Event has now started for IdleOn, returning the Buried Treasure Mini Game with a new Name Tag up for grabs! This is a limited-time event, so you'll want to try and complete it every day to get the most out of it.
This event will last until July 8th 2026 for a total of 18 days! The event was added for Patch V119.
Cooler Boxes
Every day you can collect 50 Cooler Boxes that drop from any mob in IdleOn. Once you obtain 50 Cooler Boxes, you'll also get 1 free try at the new Buried Treasure Mini Game located in Blunder Hills World 1.
After opening 500 Cooler Boxes, you'll be given the guaranteed reward of Treasure Nametag.

Buried Treasure Mini Game

The Buried Treasure Mini Game requires you to find gold bars in the sand whilst avoiding the game-over skulls! If you get 3 skulls, your game will end and you'll be given a prize based on how many gold bars you found.
You can find the game in Blunder Hills World 1.
You get 1 free play per day once you have found 50 Cooler Boxes.
You also get a free play based on how long you keep IdleOn open. The timer starts at 10 minutes and increases each time you get a free play.
There is a guaranteed Jackpot win after 59 plays.

Dig Treasure Hunt
Every day there is a new Treasure Hunt that requires you to type the word "dig" on a specific part of a random map in IdleOn. The prize each day is the same for all players and so is the spot.
The prize changes each day, so if you miss any days you won't be able to claim previous days.
You must be on Server Pizza Channel 1 in order to play. When you find the spot, use the chat bar to type the word "dig" and you'll be given the prize.
We'll try and keep this part of the event guide up-to-date with the latest spot throughout the event; but if we're late, use the comments section below to let players know where the spot is and the reward!
| Day | World / Map | Prize |
|---|---|---|
| 1 | Frostbite Tundra / Waterlogged Entrance | 30 Event Boxes |

Pet Bonus Token
A new Pet Bonus Token has been added to IdleOn for Patch V119.
This new token will drop from any mob and can be used only once (so obtaining multiple copies doesn't matter).
The token allows you to obtain the effect of any other Player's Pet Companion. Simply click on a player and click the Trade button; you'll then be able to see their active pet and choose whether to trade your new Pet Bonus Token for their Pet bonus.
If you ever obtain the pet you have traded the bonus for (i.e. getting it from buying Pet Crystals) you'll be refunded the Pet Bonus Token and allowed to use it again on another pet!
So in essence, you get to obtain any pet's bonus for FREE!
