Magnetic suction competitive game device and method for playing game using device

A magnetic suction competitive game device, comprising:

• a competitive game plate (1), wherein a game space (11) is formed at the competitive game plate (1);
• a plurality of magnet placement regions (12) are distributed in the game space (11);
• the plurality of magnet placement regions (12) are classified into a plurality of different types of magnet placement regions;
• the plurality of different types of magnet placement regions are crosswise arranged;
• a surface of the game space (11) is a rough surface;
• region surfaces of the magnet placement regions (12) are also rough surfaces;
• and
• a plurality of magnets (2), wherein a cross-sectional area of each magnet (2) is smaller than an enclosure area of the magnet placement regions (12), to ensure that the magnets (2) are accommodated by the magnet placement regions (12) when placed in the magnet placement regions (12);
• a magnetic suction force or a magnetic repulsion force is generated between two adjacent magnets (2);
• if a weight of each magnet (2) is set to m, and a gravity generated from the magnet (2) is set to G, there is G=mg;
• g is a gravitational acceleration which is about 9.8 N/kg, wherein N is the unit “Newton” of force;
• a friction coefficient of the rough surface is set to u;
• when the competitive game plate is horizontally arranged, a friction force generated by a single magnet (2) at the rough surface is f=μG=μmg;
• friction forces generated by two magnets (2) that generate the magnetic suction force at the rough surface are respectively set to f1 and f2, f1=μG1=μm1g, f2=μG2=μm2g;
• f1>f2 when G1>G2;
• when two magnets (2) are respectively placed in two magnet placement regions (12), under a condition that center points (21) of the two magnets respectively correspondingly overlap center points (121) of the magnet placement regions where the two magnets are placed, the magnetic suction force generated between the two magnets (2) is set to H;
• the magnetic suction force generated between two magnets (2) arranged in two adjacent magnet placement regions (12) is set to H1;
• the magnetic suction force generated between two magnets (2) arranged in two magnet placement regions (12) that are spaced apart from each other is set to H2;
• and then, H1>f2 and H2≤f2 are satisfied.
