Game rules

Preparation: 2 or more people, a deck of playing cards, remove the jokers. A is the smallest, followed by 2 to 10, J, Q, and K is the largest; the suits do not compare with the size.

Each person draws a card and puts it directly on their forehead without looking at the face of the card; they cannot see it, but others can.
Before opening the cards, you can ask any player "Do you think I need to change?" The other party can answer honestly, or they can deliberately mislead.
Each person can decide whether to change cards, and there is no limit to the number of times; when changing cards, the forehead card is returned to the discard area face down, and then one card is drawn from the card pile. The new card cannot be looked at.
When everyone is ready, they reveal their cards at the same time, and the one with the lowest points loses. When there is a tie with the lowest points, the tied players will each draw an open card and weigh the ratio until there is a loser.
