@lexulous said in Game Completion Rate - GCR:

Before a player joins a "hosted game", they are shown all information including the opponent's game completion rate, dictionary setting, expected rating change and opponent information. Hence joining a game and deleting it immediately is unfair to the opponent (they need to place another request for no fault of theirs).
A player's GCR reduces each time they delete a game that they have joined from a hosted table. If the GCR falls below a specific level, the player is prevented from joining additional hosted games. The player can continue to post requests or play with friends.
How to maintain a healthy GCR?
Make sure you try to finish every game you have started playing and do not delete games without a proper reason.
How to improve your GCR?
You need to complete more games (either with friends or via hosted game requests of your own) and your GCR will keep rising.
Another way to improve your GCR is to play against opponents with similar or higher skill levels. If you consistently beat weaker opponents, your GCR may decrease, as the system expects you to win those games. However, if you lose to weaker opponents, your GCR may also decrease, as the system expects you to win those games.

Therefore, to maintain a healthy GCR, you should aim to play against opponents of similar or higher skill levels, where the outcome of the game is uncertain. This will help you improve your GCR over time as you win more games against challenging opponents.
