Secrets of the Universe (Mark of God)

Gameplay: Align outer ring 1 with inner ring 1. Then, divide the number in the middle ring by the number in inner ring 7. The result is the decimal value on the outermost ring, clockwise.

1÷ 7 = 0.142857142857... (repeating block is 142857)
2 ÷ 7 = 0.285714285714... (repeating block is 285714)
3 ÷ 7 = 0.428571428571... (repeating block is 428571)
4 ÷ 7 = 0.571428571428... (repeating block is 571428)
5 ÷ 7 = 0.714285714285... (repeating block is 714285)
6 ÷ 7 = 0.857142857142... (repeating block is 857142)

The number seven, hailed as the 'number of God', holds a unique and profound meaning of completeness in humanities, mathematics, and nature.

In ancient cultures, seven symbolizes order and completeness. God created the world in seven days, resting on the seventh; the ancient Babylonians called the sun, moon, and five visible planets the 'Seven Luminaries', defining the rhythms of celestial motion. The Chinese 'I Ching' also contains the wisdom of 'seven days of return', believing that the waxing and waning of Yin and Yang occur in seven-day cycles, where all things complete a transformation from prosperity to rebirth.

From a mathematical perspective, seven possesses an inherent mystical quality. The 'carousel number' 142857, born from 1 divided by 7, only shifts its digits when multiplied by one through six, but transforms entirely into 999999 when multiplied by seven, forming a wondrous cyclic destiny. As a prime number that cannot be evenly divided, it also represents a pure origin independent of external factors.

Nature and living organisms also conceal the 'seven' code: a rainbow has seven colors, musical scales have seven notes, and the limit of human short-term memory is precisely '7±2 chunks'. Even human physiology follows a seven-day rhythm, common colds often resolve in seven days, and female growth cycles are phased in seven-year increments (e.g., 'Heavenly Gui arrives at two sevens').

Across time and space, seven encapsulates the profound meanings of order, completeness, and origin. It is both a cosmic constant and a natural law etched into DNA, and it is precisely because of this unique quality that it is revered by people as a symbol of divine origin.
