Bonus Challenge

Bonus Challenges are Bonus Games in Super Mario World 2: Yoshi's Island, its remake, and Yoshi's Island DS. When a Yoshi reaches the goal roulette and the roulette lands on a flower, then a Bonus Challenge can be instantly played. In the original Yoshi's Island, a specific Bonus Challenge can also be unlocked and played anytime after getting 800 points in a world; in the later two games, they can be accessed after getting 700 points in a world.

The list of Bonus Challenges are below.
 * Scratch and Match
 * Flip Cards
 * Drawing Lots
 * Match Cards
 * Roulette
 * Slot Machine

In Yoshi's Island and its remake, the Bonus Challenges available after getting a flower at the goal roulette depends on the world currently being played, as follows:
 * World 1: Flip Cards / Scratch and Match
 * World 2: Drawing Lots / Slot Machine
 * World 3: Match Cards / Roulette
 * World 4: Scratch and Match / Drawing Lots
 * World 5: Flip Cards / Roulette
 * World 6: Match Cards / Slot Machine

Trivia

 * Drawing Lots was the only Bonus Challenge that did not appear in Yoshi's Island DS, most likely due to the fact that the game has only five worlds as opposed to six, and that the player couldn't use items in this game.
 * In Yoshi's Island DS, the background music shares some similarities with the underwater theme from the original Super Mario Bros.
