Model Nr: MH-06
Manhole is a game in which you have to help the people over the water by moving a manhole cover under them.
Game B requires more coordination, technique and timing.
Maximum score is 999 and when the score reaches 300 all miss marks will clear and if no misses are recorded all points are awarded double score until a miss is made.
Cheats and tricks:
When pedestrian passes each manhole without falling into the sewage, a point is scored.
When a pedestrian falls into the sewage a miss is scored. Three misses and the game is over.
If you hold in Game A or Game B key the highest previous score will be displayed. If the unit is left as it is after game is over, time display will appear in about four minutes. A game is not interrupted even if TIME key or other game keys are depressed during game playing. Pressing ACL switch or removing batteries erases high score from memory.
Issue Differences (click to enlarge pictures)
The table will show how to tell the different Issues that were made:
The battery covers seem to have a number on the back, but they seem to vary a lot and I won't even speculate what the difference is.
