The Scrabble portion of Spellwood is fine; there are the usual double- or triple-letter pieces on the board and special tiles you can use to help give you an edge. It does, however, seem far too coincidental that the AI almost always has the right tiles to create elaborate words, even on the easiest difficulty, whereas youll end up with nothing but consonants or vowels every now and then.
I havent had a chance to test it, but prior to the update words like June and Jane werent recognized, so I sure hope they realize those are valid words, especially when the AI plays pronouns and various other questionable words as well.
That being said, the RPG portion of the game is mediocre at best. After defeating the boss of each tower youre awarded a piece of equipment. First is a cap, second wand, and third and fourth are a bag. Problem is, its pointless because the bonuses these give are miniscule compared to the items the AI has equipped. The problem, then, is that unless you pay another $1 to unlock the countryside campaign, youre stuck with these 4 pieces of equipment.
You get exp per opponent defeated, but only for the first time you win, leaving little incentive to re-play past levels.
It seems you can only duel your friends through GameCenter and/or FaceBook, but not against random people. If thats the case, Scrabble and similar clone games would be better because they at least give you a wider range of people to play against. Additionally, in Spellwoods multiplayer, equipment comes into play, so people who are further along in the campaign mode (as well as having purchased the countryside campaign) will have an advantage against those who dont.
Overall, its an okay game, but its main highlights seem to just be its cute and cartoony aesthetics and an attempt to incorporate RPG-elements. Other than that, the various Scrabble-focused games are a better experience.
