How Memory Match works

Memory Match is a vocabulary game. Every pair on the board is an eye care term and its definition. Turn over two cards at a time; a matching term and definition stay face up, anything else flips back. Clear the board in as few moves and as little time as you can.

Choose your certification track (COA, COT, CPO or CPOA), a single content area or all of them, and a difficulty: Easy has 6 pairs, Medium 8 and Hard 12. Your best time and move count are kept for each difficulty, so you have a score to beat next time.

Exam questions assume you already know the terminology. Matching each term to its meaning is a quick way to drill it between longer study sessions.

Included in every paid plan, for each certification track your plan covers. New here? Try the free COA Daily Challenge, read the free COA study guides, or see plans.
