It is a game where you control Mario around a Cement Factory (Duh!). Mario is operating 2 concrete mixers, feeding concrete into the hopers. To get to the 4 different valves Mario has to hop on to a lift. Each hopper holds 3 loads of cement, so it is crucial not to let them overflow.

Game differences:

Game B requires more coordination, technique and timing.


Highest possible score is 999. 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:

Remember each hopper holds 3 loads of concrete (A warning signal will sound when the hopper is full). Only one load of concrete flows with each press of the button. Make sure you don't overflow!!!!
There is also a shelter on the lower left which he can grab if he can't get on an up lift from the down lift. Unfortunately there is no such escape if you are on the up lift.


1 point for each load of concrete emptied from the upper hopper to the lower hopper and 2 points for each load emptied from the lower hopper into the truck.


When concrete overflows a hopper and lands on the truck driver below. When Mario tries to get on a lift and misses, or when he rides the lift to the ceiling or the basement. When you have 3 misses (shown by Mario's on the upper right side of the screen.), the game ends.

Other notices:

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 five 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.

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.
