Avatars in Lumines Remastered are cosmetic profile pictures that you can unlock by achieving various milestones throughout the game. They serve as a visual representation of your accomplishments and dedication to Lumines. While they don't affect gameplay, collecting all of them is a fun side goal for completionists.

Common Avatar Unlock Conditions:
- High Scores: Achieving certain score thresholds in Challenge Mode or Time Attack.
- Chain Milestones: Reaching specific chain lengths (e.g., a 10-chain, a 20-chain).
- Game Mode Completion: Completing all stages in Puzzle Mode, Mission Mode, or defeating all CPU difficulties.
- Skin Unlocks: Unlocking a certain number of skins or all skins.
- Total Playtime: Some avatars might be tied to cumulative playtime across all modes.
- Specific Feats: Very rarely, an avatar might be tied to a unique, challenging feat within a specific game mode.
The game usually notifies you when a new avatar is unlocked. You can then select your preferred avatar from the profile or options menu. Keep playing and exploring all game modes, and you'll naturally unlock many of them.
