General info
SendouQ is a community made matchmaking system. It features leaderboards and a season system. Everyone is free to join no matter if they are new to competitive Splatoon or a top level player. The system aims to connect people with similar skill levels with each other. It's different from what the game offers (Anarchy Battle, X Rank etc.) in that the sets are best out of 7 and you choose your teammates.
Before joining
Make a sendou.ink account
Click “log in” on the front page (mobile) or top right (desktop). Agree to connecting your Discord account, you will be redirected and the account is made.
Select your map pool
Optional - if you don't have a preference then skip this step and other players in the lobby get to choose. On the settings page first select your preference of each of the five modes. Avoid means you'd rather not play the mode. Neutral means you don't have strong feelings either way. Prefer means you like this mode over neutral modes. These choices later affect what modes you will be playing. In SendouQ you might play a set with SZ/TC/RM/CB or only TC or TC/RM or any other combination. It all depends on what players in that match have chosen.
For each mode that you didn't avoid also choose 7 maps. Again the choices you make are in part deciding what map lists you will be playing on. You can't choose maps that are excluded from the map pool for the season (banned). Banned maps are typically those with least likelihood to appear in tournaments or generally have been very rarely picked based on the data of previous seasons.
Finally hit save to save your preference (also do this for each step below).
Weapon pool
Choose up to 4 weapons that you will be playing. Don't skip this step as it's important for team building reasons.
Voice chat
Select whether you can voice chat, listen only or neither. Also select the languages you speak. Again this is an important step so don't skip this one. Note if you select that you can voice chat it's expected that you will join the voice chat when asked.
Avoiding Splattercolor Screen
You can select to avoid Splattercolor Screen. This option exists for accessibility reasons. Toggling this option means screen will be banned in all sets you play. But also note that groups challenging your group will see that screen would be banned in your set so it's not advised to select this option unnecessarily.
Bio
On your user profile page put a short description to your bio about your previous competitive experience etc. information you think would be useful for team building purposes.
Friend code
On the SendouQ front page enter your friend code. It's your responsibility to make sure it matches the account you will be playing on. Anything else will be considered alting by default which is against the rules. If you need to change friend code after setting it use the helpdesk on our Discord server.
Reading rules
Read the rules. You agree to follow them when you play SendouQ.
Joining the queue
Joining solo
Click “Join solo” on the SendouQ front page.
Joining with 1-3 mates
Click “Join with mates” on the SendouQ front page. On the following page share the invite link with your mates. You can also “Quick add” mates if they are in the same sendou.ink team or they played with you before and selected the option to let you do this.
Click “Join the queue” after your mates have joined.
Finding a group
If you didn't join with a full group of 4 next you will join a screen where the aim is to get a full group. You do this by getting other people join your group or merging with other groups. Click the “Invite” button for any group you would like to group up with considering the weapons, skill level and other factors. There is no downside in sending more invites so it's not advised to only send one invite at a time and waiting for them to accept but keep sending new invites till you find a match.
Naturally other groups can also invite you in which case it's up to you to decide whether to accept or not. There is no explicit decline invite feature so if you don't want to group up then just don't click the “Group up” button.
Repeat this grouping up process till you have a full group of 4.
Plus Server icons
Icon above means that the player is a member of the Plus Server. See FAQ for more info.
Adding a note
You can add a public note if you want to communicate something to other groups that might influence grouping up somehow. E.g. message that you will be streaming the set with VC so people who don't want to appear on stream can avoid your group.
Inactivity
If you don't do any actions for 30 minutes your group will be marked inactive and hidden. Click the prompt that you are still looking to be visible again.
Group managers
Only the group owner or manager can send invites. When groups merge then the previous owner and manager will have it in the new group as well. Group owner can give the manager role by clicking the star icon and selecting "Give manager".
Finding an opponent
Like with finding a group you will get presented a list of groups you can challenge. Typically choosing a group with similar skill level might result in the best match but you are free to challenge group of any level (and they are free to not accept). You will also see the modes the set would have before deciding on challenging/accepting.
Rechallenging
Sometimes it can take a while for a group to accept your challenge. If you don't have a strong preference about modes you might consider "Rechallenging" the team on their mode preferences. In some cases it might help you get into a match faster.
Playing the match
When you have a match it's time to join the room. The person who first volunteers in the match chat will host the room. Use the pool and password provided. As host remember to use the Y button (letter icon) to send invites periodically as if people joined the pool after you by default they don't see the room. As a player joining the room the room will appear in the "letter tab". Press X to refresh the view and if you are not seeing it then ask the host to send you an invite.
Then just play matches till either team has reached 4 wins and report the score. Your SP will be adjusted after both teams report the score.
Canceling the match
Match can be canceled if both teams agree to (read the rules). Click the cancel button to request canceling the match. If the other team agrees then they can also click it to confirm and lock the match.
Enemy not reporting
As the first measure contact the opponent and politely remind them to. If that is not working then come to the helpdesk channel on our Discord to get help from admin.
Private note
After the set you can leave private notes about your teammates. If you had good experience with someone why not leave a positive reminder so you remember to group up with them in future as well? Likewise if you did not have such a good time playing with someone you can leave a negative note. The sentiment affects their sorting in the group up phase. Clicking their avatar in the group up phase will show what you wrote about them.
Joining again with the same group
As a group owner you can use the "Look again with same group" to instantly join the queue with the same roster. Note that this button should only be used if you checked with all your mates that they can still play another set.
Stats
While reporting the score you can also report weapons. You can view statistics on your user profile. You can for example see your win rate with different weapons on each stage by clicking its row on the "Stages" tab or view your winrates with different mates on the "Teammates" tab.
Other topics
Ranking algorithm
The ranking algorithm used is called OpenSkill. Most common question people have is how is it possible that their higher ranked mate loses less points than they do. This is possible because of “confidence rating” which is an internal value that goes down when you perform as the algorithm expects you to perform and goes up when it's the opposite. Check Joy's Twitter thread on a longer explanation.
Only the whole set's result matters so points gained/lost are the same whether the set ends 4-3 or 4-0.
Ranking tiers
View full list of tiers and current SP criteria
You will see your ranking tier for the season after completing 7 sets (calculation).
Unlike most other games in SendouQ ranking tiers are strictly based on percentage. This means that e.g. Leviathan is always the top 5% of the players. This also means that your ranking tier might go up or down without playing when other players' rankings change.
There is also a tier recalculation in the first week of the season that can change your ranking tier significantly. When there are less than 200 entries on the leaderboard tiers are calculated based on everyone's powers. After crossing that threshold tiers switch being calculated based on players on the leaderboard only.
Rank history
You can see your ranking history graph on your user profile's “Seasons” page. Note that to to view your rank history, two conditions must be met: 1. You have completed a minimum of 7 sets. 2. These sets were played across 3 separate days, according to server time.
Team ranking
Team ranking is just ranking of unique rosters of 4. This means that If your team has 5 members (A, B, C, D, E) then you would potentially have different rankings with A-B-C-D, B-C-D-E, A-C-D-E etc. You don't need to do anything special such as creating a team on sendou.ink to start playing for a team ranking. The system automatically tracks team ranking for each unique roster that plays.
Note that the default team leaderboard only shows the highest team ranking per player so you might not show up at all if the mates of your rankings have higher rankings with other players.
Ranked tournaments
In addition to SendouQ, tournaments can also affect your ranking. Check the calendar to find tournaments hosted on sendou.ink. If on the registration page it has the “Ranked” badge then you know it is a ranked tournament. In ranked tournaments each set is counted as a SendouQ set. Ranking changes are applied when the tournament ends and is finalized by the TO.
If you sub around then note that only the people who played in the set have their ranking changed. If you sub in the middle of a set then it's counted based on people who played the majority of the set.
SendouQ Season Finale
Top 12 teams are invited to a SendouQ Season Finale event that typically happens 1 week after season ending. It has a price pot of $750 and is Splat Zones only.
Off-season
For off-season (usually around 2 weeks between seasons) SendouQ is not available.
