Daily Check-In
Select Check In from the sidebar on My Home.

You can also check in through the WeChat official account by selecting Go Player — Check In. Each WeChat check-in awards 1 Weiqi Bean.
Check in for 100 consecutive days, or reach any multiple of 100 days, to receive 100 Weiqi Beans.
A full year awards 365 Weiqi Beans, and 1,000 days awards 1,000 Weiqi Beans.
You may make up a missed check-in for any day within the past year. There is theoretically no limit to the number of make-up check-ins, but each one costs Weiqi Beans. The first costs 10, the second 20, the third 40, the fourth 80, and the cost continues to double.

Note that the check-in on day 100, including every multiple of 100, must be completed normally by you. A make-up check-in counts toward the total number of days but does not award the milestone bonus. The bonus will instead be issued when you next reach a multiple of 100 days through a normal check-in.
