"UPPERCASE lowercase" is a font matching card game that aims to improve one's font-identification skills. The cards all contain the letter "A" in its respective font and the goal is to match the lower case "a" to it's uppercase counterpart. The guide lines on the every card are based on the Cap Height, X-height, and Baseline of the uppercase "A" from the font Helvetica. Placing the cards face up, the player attempts to match an uppercase A to it's corresponding lowercase a and then flips the cards over to reveal the font family they are from. If correct, the cards stay face down, if not, they are flipped back over and the player can try again.
