About this game
JTris 1.01 is a falling-block puzzle with one- and two-player modes. Fill horizontal rows to remove them, gain points and make room for the next pieces. Every ten cleared rows advances the level and increases the falling speed.
In one-player mode, Left and Right move the piece, Down lowers it, S rotates clockwise and A rotates counterclockwise. Two-player mode changes player one's movement to F, H and G while keeping S and A for rotation. Player two uses the arrows with L and K for clockwise and counterclockwise rotation.
F9 pauses the game. The options let you redefine keys and adjust keyboard sensitivity, useful if repeated movement makes placement difficult. Music and background controls are separate from gameplay: F7 and F8 change tracks, while F10 changes the wallpaper. Build for multiple-row clears without leaving a stack too high to recover.
