From this page, you can pretty much instantly queue up for the Tournament game mode. Tournament play occurs in 4P and 3P forms. The entry for the 8/9 player Tournaments is 500 Coins. The entry for the 32/27 Player Tournaments is 10 Vouchers. In the Coin tournaments, you have to win twice in a row. In the Voucher tournaments, you essentially have to win 3 times in a row. In 4P mode, the winner of the hand and one other player advances. In 3P, only the winner advances. There is no Ranking or Rating awarded from Tournaments, so don't feel pressured! In the Daily Tournament modes, you really should only focus on the quickest hand you can make. There is no difference between winning with Yakuhai Nomi and Triple Yakuman in Daily Tournaments. Even dora is completely useless! Just go as fast as you can.
This is Riichi City's 'appointment' game mode. In it, up to 256 people attempt to play in a special asynchronous mode to try and reach the top. It runs every day at the time specified (in your own time zone.)There is a Morning GP and an Evening GP every weekday. There is only an Evening GP for each day on the weekend, but in the western time zones, it's more like an early morning GP. Hopefully as the western audience grows, We can get Premium GPs in our time zone!
A full GP is 13 hands (or less if you are eliminated), so please make time accordingly.
During the week, the Grand Prix on offer is a 5000 coin entry fee with prizing for the top 64, and a winning prize of 300 TP. The weekend Grand Prix has registration available during the entire week. The weekend Grand Prix is a 30 Voucher entry fee with prizing for the top 64, and a winning prize of 10 Lucky Tokens. The format of this event is incredibly interesting!
First, it starts with an East only round, no dealer retainership. Your goal is to place in the top 2 to continue into the Grand Prix proper. In this format, defense and scores DO matter. You will carry an ever increasing percentage of your winning score with you throughout the event. From here, you will play up to 4 1 round sessions, like the Daily Tournaments. You will advance if your score is still within the top 2. If you make it to the final table, one more East Only game will decide the final winner of the Grand Prix.
Lets say, for instance, you landed a dealer Mangan for 12000 points in the first East Only part of the grand prix. When you go to stage 2, the first 1 round portion, your starting score should be 31,000, or (12,000 * .5= 6,000) + 25,000.
If you don't end up winning the next hand but still move on, your starting point total should be (6,000 * .6 = 3,600) + 25,000, or 28,600. As you can see, without wins your score will decay, so make sure you keep aiming for high point totals that can move you through multiple berths of the 1 round portions of the event.
TL;DR Stay in 1st or 2nd or get eliminated.
