Halfwords
Halfwords is a compound word game that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.

Join word halves such as SUN and FLOWER into compound words until every half on the board has a partner. Each board has exactly one way to pair every half, and a join needs a clear path through empty spaces, so the order of joins matters too. There are 120 boards in six packs from Year 1 to Year 6, plus a new board every day.
How to play
- Tap a word half to pick it up
- Tap its partner to join them into one word
- Joins need a clear path through empty spaces. Every half needs a partner
The game shows these steps as you play, the first time.

Controls
- Tap a half, then its partner, or drag one onto the other
- Arrow keys and Space or Enter on a keyboard
- U or Backspace undoes
- H hints
Tips
- A half that joins several ways, like SUN with SET, RISE or FLOWER, is best left until its other options are gone.
- Tiles in the middle wait for a clear path, so join the pairs around them first; neighbours can always join straight away.
- Undo costs one of the 3 stars however often you use it, and each hint costs one, but a cleared board always pays at least 1 star.
Why does the game say a half has no partner left?
Every board has exactly one way to pair all its halves. A join that makes a real word but is not part of that pairing leaves some half with nothing to join, so the game warns you at once and lights up Undo.
Which words are used?
About 250 compound words written for the game, each made of two real words, such as RAINBOW, TEAPOT and LIGHTHOUSE. Year 1 and 2 use the simplest, Year 3 and 4 add more, and Year 5 and 6 use the whole list.
