According to Rule 7:
24-HOUR INSTANT FORFEITURE (New!) – If a player neglects to make a move for 1 full day (24 hours) and no prior arrangement was made to continue the game at a later time, then the aggrieved player may claim that round as a win by forfeiture. A screen shot showing a full day with no moves must be provided on request.
Please provide the screenshots of the games and time lapses to email@example.com
Then you can record the win by forfeiture.
