How to identify the program mahjong machine?

The method of identifying mahjong machine program is:

The easiest way, if conditions permit, is to open the cover plate of mahjong machine and check whether the belt below is smooth. If it goes well, nothing else, you can rest assured, because this is where most cheaters start to work.

Magnet test: This is a practical way to check dice and mahjong. If the magnet can be attached to the dice or mahjong, there is something wrong with it. Because normal mahjong is not affected by magnetism.

Judging from the dice: as we all know, the normal number of dice is; 6: 00 is 1, 5: 00 is 2: 00, 4: 00 is 3: 00, and the sum of the two opposite sides of the dice is 7. If mahjong machine installs the program, it is necessary to change the points of some dice (that is, to misplace the dice), because when installing the program, it is necessary to set the position of opening the door to grab the cards according to the rules of mahjong game, so as to switch back and forth the position of opening the door to grab the cards and prepare for the next deck of cards (if you don't switch, you can only play a little).
