Classic four in a row, except every chip is your face. Drop chips into the columns. The longer your line gets, the bigger you grin.
Take turns tapping a column. Your chip drops to the lowest open hole. Each chip shows the longest line it belongs to: 1 serious, 2 smiling, 3 grinning, 4 laughing and the game is yours. Photos stay on this phone.
Drag and zoom so your eyes sit on the two rings and your mouth on the dashed line. That's where the grin gets stretched.
