Quick answer
What to remember
Track new stickers per packet
Measure duplicate rate
Compare random cost with targeted acquisition
01
The probability changes
Early packets usually produce broad progress because most album positions are empty. Later packets draw from a pool in which many possible stickers are already owned.
02
Use a session log
For each opening session, record packet count, total stickers, new stickers and duplicates.
New-sticker rate
Duplicate ratio
Cost per new sticker
Remaining gaps by team
03
A practical decision rule
If several sessions produce mostly duplicates and common gaps can be traded or ordered directly, move budget toward targeted completion. Continue opening packets when the entertainment value itself justifies the cost.
