About this game

There are 25 letter magnets on a fridge door, in five rows of five. Red and Blue take turns to spell a word with them. The letters can come from anywhere on the fridge and don't have to touch.

Tap the letters in order and the word shows on the pad underneath. Tap a letter again to put it back. Then tap Play word. Words need three letters or more. If the word isn't in the list, the pad shakes and you try another.

Every letter you use turns your colour, even if it was the other player's. While you spell, a dashed line goes round each letter that would change colour, and small numbers by the scores show what each player would gain and lose.

A letter with your colour above, below and on both sides is safe, and is drawn as a solid block. The other player can still spell with it, but it stays yours until one of the letters next to it is taken. A corner letter has only two letters next to it, so it is the easiest to make safe.

No word can be played twice, and nor can the start of a word already played: after PLANET, PLAN and PLANE are out, but PLANETS is fine. The sticky note shows the latest words. Tap it for the whole list.

The game ends when every letter has a colour, and the player with more letters wins. A player who can't find a word can pass, and two passes in a row end the game too.

The spelling is Australian: colour, organise, tyre. Each game deals new letters, always with enough vowels and never a Q without a U.

On your own, you play Red against the computer. On easy it plays everyday words of three or four letters and doesn't notice which letters are safe. On hard it knows every word in the list, plays words of up to eight letters and works out how you could answer.
