Spider card skill formula

There are some formulas, such as observing first, emptying the space and establishing the sequence.

1. Observe first: Before moving the cards, carefully observe the overall layout of the cards in order to make a more informed decision.

2. Clear the empty space: give priority to using the empty space, move the cards to the empty space, and create more opportunities for moving combinations.

3. Establish a sequence: try to establish a continuous sequence, that is, arrange adjacent values in ascending or descending order to create liquidity and vacancies.
