Sixteen tiles. Hidden among them are four four-letter words that use every tile exactly. Tap tiles and they go straight onto the highlighted row; tap Place word to put the word down.

• Tap any other empty row to put your word there instead. Tap a word on the grid to take it back.
• Columns that happen to read as a word score a bonus too, top to bottom. A full four-letter column scores double.
• With all sixteen down, drag a word up or down to try another order, then tap Finish.
• Stuck? Hint gives you a clue, then a letter, then the word. If you pause for a while, a clue appears by itself.
• Every word you place gets its meaning. My words keeps them all.
