Scratch card

Scratch cards are a bonus feature in Mario & Luigi: Bowser's Inside Story and its 3DS remake.

Usage
These cards allow Mario, Luigi, or Bowser to receive a refund for some of the coins spent while shopping. Having a higher 'Stache or Horn statistic will affect the player's chance of winning. After purchasing an item from the shop, the player may be given the option of scratching a scratch card. A Mushroom refunds 10% of spent coins, a Fire Flower refunds %20, and Super Star refunds %40. Scratching a Fawful will reward no bonus.

There are three different types of scratch cards, depending on the 'Stache and Horn statistics. The 'Stache number represents Mario and Luigi's combined score for the statistic, as indicated below.
