Spade Panel

Spade Panels, also known as Spade Bonus Panel Minigames or ♠ Panels are small panels on overworld maps in Super Mario Bros. 3 which can be used to earn extra lives for Mario or Luigi. Once they enter one, the player can play a minigame similar to a slot machine, in which parts of pictures slide past on panels and the player must line up three of the same panels to make a picture and win extra 1-Ups. There are Mushroom, Flower, and Star panels, granting 2, 3, and 5 extra lives when lined up, respectively, similar to the goal at the end of each level. If any of the panels are mismatched, no extra lives are awarded.

In the Game Boy Advance version (Super Mario Advance 4: Super Mario Bros. 3), if a Spade Panel is matched up correctly, further Spade Panels will change to . The Stars are replaced by Super Leaves that give 7 extra lives. Clearing one of these turns further Heart Panels into , and the Super Leaves change to "3" icons that reward 10 extra lives. Clearing a Club Panel turns further panels into , where only one picture can be lined up, making it impossible to lose. Earning a minimal amount of lives at previous panels will result in a mushroom picture, while higher amounts yield a random picture, and gives the corresponding amount of extra lives. If Mario or Luigi clears a Diamond Panel, or fails at any of the other ones, then all Panels will revert to Spade Panels, restarting the process.
