Goal
Match identical numbers to clear all pairs.
A concentration-style time attack shaped by 2-second flashes and miss penalties.

Memory Lock is a concentration-style memory card game where uncleared cards flash for just 2 seconds. Wrong pairs add time instead of ending the run, and each extra flash also adds a penalty. Decide when to trust memory and when to reveal again for the fastest clear.
