In Tea Ceremony you have to get the highest value 'hand/tea set' out of all the unfolded players, at the end of the round. The 'hands' are different coloured teas.
At first you can see only the values in your own hand/table of teas, but as play progresses you may be able to see others.
On your turn, you may lock a table of teas, preventing it from being stolen, but also revealing it to other players. Do this with tables you want to keep.
Or you may switch one of your own tables with one of another player, in an attempt to improve your own hand/tea set. Note: this may backfire. You may also raise during your turn.
If you win the round, you win all the btm in the Teapot.
