This disclosure is directed to techniques for presenting a scratch-card style interface using a touch-sensitive device. The touch-sensitive device is configured to present a first image using a display of the device. The first image may include a plurality of portions. The plurality of portions may be a plurality of overlapping image particles, or may be a plurality of image layers. The device may detect a first user interaction, and graphically remove a first number of portions of the first image in response to detection of the first user interaction. The device may detect a second user interaction, and graphically remove a second number of portions of the first image in response to the detected second user interaction. Graphical removal of the second number of portions may at least partially reveal a second image presented using the display of the device.
