Snappywords - Puzzles & Word Games - LITS-Puzzle

LITS is a logic puzzle where you must place exactly one tetromino in each marked region. Identical shapes—including rotated or mirrored versions—may not touch each other horizontally or vertically. The shaded cells must form one single connected area, and no 2×2 square of shaded cells is allowed. LITS challenges your ability to think ahead, recognize patterns, and visualize spatial relationships.

5 Tips for Solving LITS Successfully

1. Identify certain placements first

Start with regions where only one tetromino shape fits—this gives you a quick foothold in the puzzle.

2. Watch for shape contact rules

Make sure two identical tetromino shapes do not touch each other horizontally or vertically—this is a common mistake.

3. Avoid 2×2 blocks

Ensure that shaded cells never form a square of four connected tiles, as this violates the rules.

4. Use elimination logic

It's often more effective to rule out impossible positions than to guess the correct one immediately.

5. Track connectivity

All shaded cells must form a single, continuous area—regularly check that this remains achievable as you progress.
