Recommendations for spelling games/apps please

[CramptonHodnet]

We've got the maths apps etc for DS sorted now, thanks to everyone who recommended on here but now I need to pick your brains for the best spelling games and apps.

We have Junior Scrabble which DS, who is dyslexic, struggles with. He's past the basic cat/dog preschool stuff but is definitely not at his spelling age (8). Free apps would be best so we don't waste money on stuff he can't get on with.

Or any good board games, even, although they do tend to lead to arguments with DD, who is a good speller and competitive game player

We've tried (and given up with) squeebles. Also did several books of "Apples and Pears" with little result. DD2 reads a lot now (especially now she's not at school - so much more reading time available) and I've also tried just leaving it and waiting for it to sort itself out by osmosis, but spelling continues to be diabolical. So very interested in suggestions!
