The Chasm of Challenges is a minigame that can be played by Sora in Kingdom Hearts II. It is located in the Cave of Wonders at Agrabah. It requires Sora to defeat all the Heartless and descend all platforms within two minutes.
In the first visit to Agrabah, Sora must complete the Chasm of Challenges to proceed to the Treasure to obtain a treasure to barter for Jafar's lamp from the Peddler. As a reward for finishing the challenge, the door to the Treasure Room unlocks.
