Normally it eliminates teams with lower Keys every day, and the elimination line will go up gradually.

The elimination line is based on the following rules：
- 1st round: teams that less than 10% of the first team's keys will be eliminated.
- 2nd round: teams that less than 20% of the first team's keys will be eliminated.
- 3rd round: teams that less than 30% of the first team's keys will be eliminated.
- Until 90%.
- Then, the elimination continues, but the ratio remains unchanged at 90%

Whenever there is only one team left, the game ends.

So one season could last two weeks or just two days, then another season begins.

There is no end of the game!
