LEV     PUZ    

LITS, also known as Nuruomino, is a logic puzzle published by Nikoli. The puzzle consists of a rectangular grid divided into regions. The goal is to color exactly four connected cells in each region to create an L, I, T, or S shape. We call such a form a tetromino. A popular use of tetrominoes is in the video game Tetris.

Follow the rules below:

  • You can rotate or flip tetrominoes.
  • Tetrominoes that share a border cannot be of the same type.
  • All tetrominoes must be connected horizontally or vertically.
  • The tetrominoes may not cover 2x2 cells.
