If it is late at night, there will definitely be fewer people playing games than at night or during the day, and there may be a situation where people can't be matched (the matching time will be longer than usual)

2. Reasons for the achievement:

If the summoner's level is still around 10 or lower, it may not match the opponent, and the level is also a factor.

3. Teams that have not teamed up for the time being can compete:

If you are playing games with a good friend in a team and three or even four or five people match, you may not necessarily meet the same team.

4. Regional factors:

Although there are many League of Legends players, there are still differences in the number of people in such a large area. There will be more people in earlier regions and newly opened regions.

5. System error:

Sometimes it may be a system error. After logging in for a few minutes or even ten minutes, there is no prompt to match the opponent. We can try to start pairing again.
