 Had some instant noodle around midnight, fell asleep around 1:30 and got up at 7 to have breakfast. Played games in the morning and afternoon. Specifically, the average time of finishing a soduku with extreme difficulty was lowered under 10 minutes. It's for all games, from the very start, so the average time for recent hundreds of games would be even less, like 6 minutes or so. Watched football games after dinner. Slept around 5.5 hours and completed nothing today.
