There are 3 possible scenarios:
If you disconnected (have not completed the game) you get a penalty of -20 (your ELO is reduced by 20).
Game suspension
If the game gets suspended while playing (e.g. you get a phone call), your "suspension count" is incremented.
When the "suspension count" reaches 4, you automatically lose the challenge.
