What is different about hard mode?
The standard game uses a four-by-four grid, while hard mode expands the board to six rows by four columns. More cards mean more locations to remember before a pair is found. Separate best times by mode let players compare progress on equal terms.
What does the game measure during a round?
It keeps a move count and a running timer while players search for pairs. Those two measures show different kinds of progress: someone may finish quickly with extra turns, or take longer while remembering more cards. The win screen gives players a chance to start another round.
Can the card pictures be changed?
The current sample uses drawn fruit and vegetable faces with sound and music. A new version could use animals, symbols, landmarks, or words from a learning topic. Clear images and a consistent back design matter because the game depends on remembering where each face appeared.
