Word Stacker

Build the tallest tower of words — one word at a time.

Word Stacker is a word puzzle for Windows where every word grows out of the letters of the one beneath it. Each choice shapes what you can build next. Chase records alone, or race friends and strangers online.

How it works

1. Choose a level (4 to 15). That's the length of your words.
2. Pick your letters from 10 random consonants and 4 random vowels.
3. Place your tiles on the row and type the rest of the word.
4. Keep stacking. Carry letters from each word up to the next row. No repeats allowed.
5. Watch your 10 hearts. Wrong guesses and blank squares cost lives.

Two ways to score

• Stack Height: how many words are in your tower.
• Points: classic word-game tile values, so rare letters like Q and Z pay off.

Every level has local and global leaderboards, and you can view any tower on them.

2-Player Online

• Tower Race: same starting letters, separate towers, and a word played by either player is gone for both. Most points in 5 minutes wins.
• Row Grab: one shared tower. Race to finish each row first, and claim the most of 10 rows to win.
