What is Letterbox?
Letterbox is a three-by-three grid puzzle. You place letters from a reserve to form words across rows, columns, and diagonals. The game provides twelve letters for nine squares, along with a timer and a score that starts at zero.
How to play Letterbox
Press “Start Game” to open the board. Select a letter from the “Available Letters” reserve beneath the grid, then drop it into one of the three columns. Each column fills from the bottom up, so you cannot place a letter in any open square. Keep placing letters while checking the eight possible lines: three rows, three columns, and two diagonals.
A nine-square board in which every direction counts turns each placement into a strategic choice. There is no hidden word to discover. The fixed reserve, the compact grid, and the running timer mean that positioning determines the score more than vocabulary. The central square belongs to four lines at once, making it the most valuable and most restrictive position on the board.
Reading the feedback
The interface shows a running timer, a score, and two information badges. No attempt counter or target word list appears. The welcome screen mentions bonus points tied to the timer, but the scoring breakdown does not display during play. The grid and the reserve are the only context provided.

Tips for better placement
The central square participates in a row, a column, and both diagonals, making it the most rewarding and most limiting position. Plan its use carefully.
Letters drop into a column rather than into a free square of your choice. The order in which you place them determines what space remains in each column afterward. Watch the column heights as you work.
