Tetra Legends is a browser-based, single player fan game in development created by Dr Ocelot. It is the spiritual successor to his retired Tetr.js modification. A variety of guideline and retro modes are present, in addition to its original Tetra-X modes.
The player can customize controls, rulesets, audio and video options to their liking. The tuning menu contains tuning options that can be changed, including the option to override the rotation system to a specific one, DAS, and ARR. If the rotation system is set to Auto, the game automatically selects a rotation system specific to a mode (Guideline: SRS-X; Tetra-X: Tetra-X, etc.).
A total of eleven modes are available, each with a different objective and gameplay.
There are six guideline modes playable. All of these modes use guideline standards, as the name implies.
- Marathon: A standard game mode where the objective is to get the highest score possible. The starting level (Lvs. 1-20), line goal (150, 200 or endless) and level cap (Off, Lv. 15 or 20) can be adjusted. This is the mode the player is taken to when Quick Play is selected from the main menu.
- Sprint: A mode where the player has to clear the line goal as fast a possible. The goal can be set to 20, 40, 100 or 200. Regulation mode can be toggled on or off, which removes entry and line delays.
- Ultra: A time-limited score attack mode. The time limit can be set to 2 or 3 minutes.
- Master: A difficult 20G mode with 30 levels (Lv. M1-M30) where delays decrease as the level increases. As with Marathon, the starting level can be changed. The lockdown modes are Forgiving (infinity), Limited (default) and Strict (step reset).
- Survival: The player must perform techniques that send lines in multiplayer to prevent incoming garbage lines from entering the field. The maximum number of lines that can be blocked is determined by the selected difficulty.
- Combo Challenge: The objective is to get the highest combo possible within 30 in-game seconds. Exclusive to this mode is the hold button modes: Skip which allows the player to skip up to twice with one skip being replenished for every piece locked, and the normal Hold option.
The Tetra-X modes are modes that are original to Tetra Legends. They typically use the Tetra-X rotation system, have a different scoring system, all spins and a 20G soft drop speed.
- Standard: Similar to Marathon but with different speeds.
- Pro: A difficult high speed mode with 10 "mach levels" that increase for every 20 lines. The next previews, if set to 2 or higher, become invisible when a player goes up by one mach level, with the lowest one possible being 1 at level Mach 6. The game ends at Lv. Mach 10 with 200 lines.
|Lv. Mach 2||The sixth next preview turns invisible.|
|Lv. Mach 3||The fifth next preview turns invisible.|
|Lv. Mach 4||The game speed is set to 20G and the fourth next preview turns invisible.|
|Lv. Mach 5||The third next preview turns invisible.|
|Lv. Mach 6||The second next preview turns invisible.|
|Lv. Mach 7||The ability to hold a piece is removed.|
The Retro modes simulate older Tetris games before the 2000s. All modes except Deluxe have no lock delay. The line clear delay varies on each mode.
- Console: Simulates Nintendo's version of Tetris for the NES. This is currently the only mode in the Retro category where the starting level can be changed (Lvs. 0-19).
- Handheld: Simulates the Game Boy Tetris game.
- Deluxe: Simulates Tetris DX for the Game Boy Color.
