# GameHzLab

> GameHzLab is a free online games portal where every game runs instantly in the browser — no download, no installation, no signup. Its distinguishing feature is **Game DNA**: a system that scores every game across six dimensions (Stamina, Mental, Reaction, Luck, Healing, Social) so players can find games that match their current mood and energy, not just a genre.

Key facts:
- 200+ free HTML5 browser games, playable on desktop and mobile.
- No download, installation, registration, or payment required.
- Bilingual: English (default, /...) and Simplified Chinese (/zh/...).
- "Game DNA" matching lets users pick games by mood/state, not only by category.

## Game DNA (what makes GameHzLab different)

The six Game DNA dimensions, each scored 1–10 per game:
- **Stamina** — endurance for long, high-intensity sessions.
- **Mental** — brainpower for strategy, logic, and planning.
- **Reaction** — reflex speed for fast, twitch gameplay.
- **Luck** — tolerance for randomness / RNG.
- **Healing** — how calming and stress-relieving the game is.
- **Social** — solo focus vs. multiplayer/competitive.
