Every morning GuffBot sets up a game that's already under way on the Power Board and deals you eight tiles.
Your job: find the play that scores the most. You get three goes. After each one GuffBot tells you how close you came: red is cold, amber is warm, green is very close. Your best go counts, but every go after the first costs 10 points, so keep it when you're happy.
- Tap a tile, then the square it goes on, or drag it there. Once two tiles are down in a line, just tap the rest in order and they follow on, whichever way you're going. Drag tiles along your rack to rearrange them. On a keyboard, click a square and type (click it again to go down).
- Your tiles must sit in one line and join what's on the board. Every word you make along the way has to be a word too.
- GuffBot checks as you lay tiles: green means it's a real play, and shows what it scores.
- Premium squares count when you cover them: 2L 3L double or triple the letter, 2W 3W 4W multiply the whole word.
- Use seven tiles in one play for a 40 point bonus, all eight for 50.
- Speed bonus: up to a fifth of your score again for playing quickly. There's no clock on screen: it drains away over three minutes, and after that take as long as you like.
- The best play never needs an obscure word. Two-letter words are all fair game.
- A new board every morning at midnight, UK time.
