Tetr.js is a JavaScript based browser fan game. It was designed mainly as a lightweight 40 line client.
Gameplay
Tetr.js uses modern guideline rules e.g., Bag Randomizer, Hold, 6 Previews, Super Rotation System, and Lock delay. Players can customize various settings such as the controls, DAS, ARR, lock delay, and block skins. After completing a game, the player has the option to watch the replay, though they are not saved.
Modes
There are two modes:
- Sprint: Clear 40 lines as fast as possible
- Dig Race: Downstack the 10 given garbage lines as fast as possible
Farter's Dig Mod
Farter's Dig Mod is a Tetr.js modification made by Hard Drop user Farter. It has touchscreen support, and new modes similar to TOJ's Driller mode. In the new modes, the player starts with an empty field but receives garbage lines in uniform intervals. The goal is to survive the incoming flood of garbage as long as possible.
Scoring
This mod adds scoring to the game, which is mostly used for Zen mode leaderboards.
| Single | 100 |
| Double | 300 |
| Triple | 500 |
| Tetris | 800 * B2B multiplier |
| Spin | 400 * B2B multiplier |
| Spin Single | 800 * B2B multiplier |
| Spin Double | 1200 * B2B multiplier |
| Spin Triple | 1600 * B2B multiplier |
| Spin Tetris | 2000 * B2B multiplier |
| Perfect Clear | 1000000 * PC multiplier |
Both B2B and PC multipliers are set to 1 at the start of the game.
B2B multiplier doubles after each Tetris or Spin clear. Spins that doesn't clear any lines don't advance the multiplier. If a non-spin Single, Double, or Triple is cleared, this multiplier resets back to one.
PC multiplier is multiplied by 16 after each Perfect Clear performed. Unlike the B2B multiplier, it doesn't reset during the course of game.
Additionally, there is also a Combo multiplier. It applies to every type of line clear. As other multipliers, it starts at one. Each line clear doubles the multiplier, but if a tetrimino is placed in a way that doesn't clear any lines, this multiplier is reset back to one.
