Game: Sapporo
Serial Number: 388
Submitted By: Warwick Armstrong
Submit Date: 11/27/2025
Game Part: Complete Game
Country: New Zealand
Comment: The inspection date is 1978, which is quite a bit after the supposed release of the earliest serial number reported as 1971. Taken from NZ TradeMe auction site 27/Nov/2025, as this looks to be quite a rare game..
SerialBot Says: The serial number does not match any known definition masks.

Nudge History:

Nudging allows IPSND members to adjust the SerialBot score for a submission with a photo attached by determining of the photo clearly shows the existence of the serial number submitted. However, nudging is only 'Open' until there is a clear determiniation of accuracy by members. If a serial number has more than 5 nudges and the total of those nudges is greater than 4 or less than -3, then the nudge will be closed automatically after the last nudge. If a submission is controversial and there are nudges in both the positive and negative direction, then the nudge will remain open until the balance of voting swings the point value beyond 3 (positive or negative).
