The Treasure Chest is a function in TOH2 that opens up the ability for the player to recieve trophies. (Exact the same game concept like SSMB). You put your hard earned gold coins in it and see if you have the luck on your side.

Different trophies has different % chance to be recieved. Overall is it so that the more cooler or odder trophy, the harder to get. Be aware that there could be boss and sub boss trophies that has low % chance to get.

Some trophies cant be unlocked in the treasure Chest. They must be unlocked by completing challenges, mini games or be bought in the Item Shop.
