Recognizing a pair and being allowed to collect it are different questions in Sorcerer Mahjong Marvels.
Read the symbol first
Sorcerer Mahjong Marvels presents tiles decorated with mystical artifacts. Begin by comparing the complete symbol on two tiles, not just a shared color or a small repeated mark. Similar illustrations can suggest a match before you have checked the whole design. A pair is a visual relationship, and taking a moment to identify it accurately gives the later accessibility check a specific candidate to examine.
Inspect the sides separately
The listing says to collect only open tiles and relates that condition to neighboring tiles on the left or right. Look at those sides of each candidate and use the game's own highlighting or acceptance feedback to confirm the rule. Do not import an additional top layer restriction or a precise side interpretation from a different mahjong game unless this version explains it. A matching symbol does not, by itself, establish that a tile is collectible now.
Look for a changed edge after removal
When the game accepts a pair, inspect the nearby tiles whose side relationships changed. A previously unavailable match may now be worth checking because the arrangement is different. That is a local accessibility question, not a promise that every removal unlocks a specific tile. Keeping symbol recognition and open status as separate steps makes it easier to understand why one visible pair can be collected while another remains on the board.
