What this tool does not do
This tool does not assess, score, grade, rank, or diagnose a child, and it does not claim that playing this matching game improves memory or any other skill. It only turns your chosen pair count and set number into printable cut cards.
This is a free, independent web tool. It is not the Lumi Bopomofo app, and it is not a diagnostic tool, assessment, or memory-training program of any kind.
This tool does not provide pronunciation or romanization for any symbol; use official Taiwan MOE resources for that.
How these cards are generated
Card selection and order are a fixed, documented algorithm run by this site, not a random shuffle or adaptive activity.
- Pick a pair count from 4 to 12; that many of the 37 basic Bopomofo letters (ㄅ through ㄩ) are selected in a fixed rotation based on your set number.
- Pick a set number from 1 to 99; each set number rotates which symbols are selected, so different sets cover different parts of the 37-symbol range over time.
- Every selected symbol appears on exactly two cards, and the card order is deterministically arranged from your pair count and set number — never a live random shuffle.
- Card size only changes how big the cards print; it never changes which symbols are selected or their order.
- Print the cards and play offline; nothing about your session is sent anywhere or stored by this tool.
