Game Objective

Fill the grid with tower heights from 1 up to the grid size. Each row and column must use every height once. A number on the edge tells how many towers you can see from that side; a taller tower hides any shorter towers behind it.

Complete the latin square of towers in accordance with the clues.

How to Play

Click a square, then type a number to enter that tower height.
Press Backspace to erase a selected square.
Right-click a square and type numbers to add or remove pencil marks for possible heights.
These puzzles reward careful deduction more than speed. Start with the most constrained clues, eliminate impossible choices step by step, and avoid guessing unless the puzzle specifically calls for it.

Beginner Tips

A clue of 1 means the tallest tower must be first from that side, because it hides everything behind it.
A clue equal to the grid size means the towers must rise in order from that side, from shortest to tallest.
Check both rules together: no repeated height in a row or column, and the visible tower count must match the edge clue.
