Sum Up Competitive

Your opponent and you get the same board with the same stones and the same target sums.

The winner receives score points and climbs up the season leaderboard.

After a week, the score points are exchanged for a medal. The more rank points the more valuable the medal.

The player who has collected the most and most valuable medals is at the top of the leader board.

Each week you get the new chance to receive a better medal.
