GROW

A word tree that grows from the bottom up. Make a word of the three letters at the bottom, and every row above adds one letter — rearrange them all into a new word, up to seven letters.

• Tap the letters into the row. A full row checks itself. Tap a letter in the row to take it back.
• Any real word of those letters counts, not only the one we had in mind, and a wrong try costs nothing — the row shakes, the letters go back to the tray, and you try again.
• Shuffle re-deals the tray when you can’t see it; Clear empties the row.
• You’re against the clock. It starts on your first move. The first 90 seconds are free; after that every 6 seconds costs a point, to at most 50.
• Hint locks the next letter of the row’s commonest word and costs 8 points. Lock all but one and the row spells itself out, which costs 20.
• So a tree grown in a minute and a half with no hints scores 100.

One puzzle a day. Your scores are kept — Statistics is in the menu — and Grow sits outside the daily line-up, so it never moves your day’s total.
