Using a sing-song mnemonic of made-up words works great for this short of a quiz. FXW, PCV, HLQ, UOK were easy to split into "Fox-wah, Puck-vuh, Hulk, oo-awk," and singing it to myself a few times made it so I could just keep repeating it. Then, you just have to remember the letters that made up the sounds for like 10 seconds.
Maybe make that first one red or blue? The yellow background made it nearly invisible on dark mode.
Fun quiz! Love short term memory quizzes like these. Whammies suit them surprisingly well.
