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.
