ForeverTetris

TetrisForever is a polished Tetris-style mini-game built directly into World of Warcraft.

Perfect for those little moments when you have nothing to do: while leveling professions, waiting for a boat or zeppelin, standing outside a dungeon waiting for the rest of the group, or just killing time between activities.

It features familiar Tetris mechanics including Hold, Ghost Piece, Next Queue, scoring, levels, combos, Back-to-Back clears, T-Spins, Perfect Clears, sound effects, and saved high scores — all inside a clean WoW-friendly interface.

Open it anytime with /tf or the minimap button and start playing.
