The Lower Division is a Swiss-style tournament reserved for the 16 lowest seeded players. In the first round, players will initially match up based on their initial seeding. Subsequent rounds will match up players by their win-loss record. A player will be promoted into the Upper Division once they attain 3 wins. Players with 3 losses will be eliminated from the tournament. In the event there are less than 16 players in the pool, a bye will be given to players depending on the round and their seeds.
In total, 8 players will be promoted to the Upper Division bracket, while 8 players will be eliminated from the tournament.
All matches are Best of 1 until a potential elimination match, where the match will be Best of 3.
All Lower Division matches will be determined by song wins and not overall achievement score.
Players’ initial match-ups are based on pairing the top half of players directly with their counterpart in the bottom half. Please see the following example provided by Chess.com:

| Match ID | Player 1 Seed | Player 2 Seed |
|---|---|---|
| A | 1 (i.e. 16th from the bottom) | 9 |
| B | 2 | 10 |
| C | 3 | 11 |
| D | 4 | 12 |
| E | 5 | 13 |
| F | 6 | 14 |
| G | 7 | 15 |
| H | 8 | 16 (i.e. the bottommost seed) |
