The tiles still look like a wall of symbols.
First move
Stop trying to name every tile. Sort only by family: numbered suits, winds, dragons, flowers, and jokers.
Do not escalate it
Do not test yourself on all 152 tiles or compare your speed with the table.
Recover from here
Keep a small reference nearby. Name the family first, then the number or honor. Return to the tile lesson after the game with a real set in front of you.
Words you can use: “I know this is a numbered tile; can you remind me which suit?”Practice the tile families →
