TikTok's hidden emoji system is activated by specific text codes and currently contains 46 special emoji that are not included in the regular emoji keyboard. These emojis are cross-platform consistent, feature a colorful design style, and can be used in the following scenarios by precisely entering the code:
Core mechanism
Code Trigger Rule
- Input precisely bracket-wrapped code in comments/private messages (e.g.
(thinking)
→ 🤔) - Video subtitles support direct device keyboard input or code paste (e.g.
(heart_blue)
→❤️🔵) - Some codes trigger dynamic effects (e.g.
(fire)
🔥 show flame animation)
- Input precisely bracket-wrapped code in comments/private messages (e.g.
Platform features
- Algorithms prioritize identification of high-frequency usage code (e.g.
(star)
⭐️ improves comment visibility) - There are use scenario limitations:
(sparkle)
✨ works on video descriptions(flushed)
😳 works on private messages(money)
💸 is dynamically regulated by the algorithm.
- Algorithms prioritize identification of high-frequency usage code (e.g.

Optimization strategies
Combination of applications
- Emotional reinforcement:
(angry)
😠 +(storm)
🌪️ - Scene building:
(mic_drop)
🎤💥 +(confetti)
🎉
- Emotional reinforcement:
Algorithmic adaptation
- ≤ 3 hidden emojis recommended for a single piece of content
- Regular testing of new code (e.g.
(alien)
👽 gray scale testing may exist)
Cross-end consistency validation
- Core code commonality validation (e.g.
(pray)
🙏🏼 displays consistently on iOS/Android) - Avoid display discrepancy code (live testing required)
- Core code commonality validation (e.g.
The continuous update nature of the system requires users to keep track of the codebase version, with the latest data showing that in March 2025 46 active hidden expressions are still maintained.
