The Grand Tournament was added to IdleOn in patch V1.05.

The Grand Tournament Overview

The Grand Tournament is held every day and runs for the course of a Season. You can win several cosmetic-only rewards depending on where you place at the end of the season.

Each day, all the unique Pet Companions you own will face off against another IdleOn player's pets in your bracket. If you win, you will face another player until you lose 3 times. If you get enough wins to make the 1024 bracket, you'll then be entered into a head-to-head knockout round until an eventual winner is crowned.

The winner of each daily tournament is awarded the Champion Pet, which is a cosmetic-only pet based on the division they win.

There are three tournament divisions: Bronze, Silver and Gold.

You must make sure you register each day. You can only enter a division if you have enough points from previous wins (you can move in and out of divisions).

Duplicate pets do not count.

Tournament Battles

Each day at a specific time, all your pets will face off against a random player in your division. You can view your battle by clicking the View Tournament button.

Each pet has a pre-assigned Pet Power; when two pets face off a random dice roll occurs where Pet Power helps determine the winner (the more pet power, the better chance it has of winning).

The chance is worked out as Your Pet Pet Power / Total Pet Power = Chance To Win. So if the both pets have a cumulative total of 200 Pet Power and your pet has 50 Pet Power, then: 50 / 200 = 0.25 (25% chance to win).

When a Pet wins against another, it knocks it out and it won't be able to be used for the rest of the battle. This continues until one side has zero pets left and a winner is declared.

Major Championships

At the end of each season, a special Major Championship is held. Only players who are ranked in the Gold Division can participate in the Major Championship.

The same exact tournament rules play out where each player faces off against another random player in Gold Division, until a winner is eventually declared in the knock-out rounds.

The Major Championship rewards the winner with the exclusive BIG CHARACTER reward, which basically makes their in-game character model super big like LavaFlame2.

You also get the BIG CHARACTER reward if you're top of the Gold Division Leaderboard at the end of the season.

Pet Mart

The Pet Mart can be found within The Grand Tournament UI. Here you can buy Pet Companions directly with Pet Crystals.

The pets in the Pet Mart rotate each day. The pets that rotate come from previous released Pet Companion Sets, but not from Bundles (usually).

Some of the Pets also have a discount.

If you own all the available pets in Pet Mart, you'll then be upgraded to Pet Mart+, which allows you to upgrade specific pets with Pet Crystals.

Upgraded Pets have higher bonuses than normal pets.

Free Gems

Each day you can claim Free Gems from the Pet Mart, just by clicking the Free Gems button.

You'll gain a random amount between 1 and 150 Gems!

Pet Mart Packs

Inside the Pet Mart you can also purchase Pet Mart Packs for real money.

They will only show if you do not own the Pet in the Pet Mart Pack.

The Grand Raid

The Grand Raids is a daily Raid Battle that puts your Pet Companions up against a group of pets from IdleOn (PvE!). Battles work exactly like Tournaments, in the sense that a random pet of yours will face off against a random pet of the raid.

There are three different levels of raids and you must beat each one to progress to the next level.

• Beginner Raid
• Veteran Raid
• Nightmare Raid

You can register for a raid each day and view your results in the View Raid button.

If you manage to win a Raid, there is a chance to win a new Raid Pet. Unlike other Tournament pets, these pets actually give IdleOn Bonuses.

Raid Leaderboards are based on how many pets you have left at the end of each raid.

At the end of the Season, the players who are at the top of each Raid Leaderboard will also be given the BIG CHARACTER effect for their IdleOn account.

Season 4 & Season 5

This was the first time raids were added to Seasons was in the middle of Season 4 and the raids stayed the same for Season 5.
