keep us posted on this one and make sure we hear of your updates here. Not everyone gets on Applevis, especially since Android is getting better for us.
Also, a couple more ideas for things you could sell us, some for real money and some maybe to get us to use our gold for more things, which I think is lacking right now.
1. soundpacks: these packs would alter the sounds some games made, for example, you could purchase hiss sounds for battlecats or other artillery sounds or bugle calls to sometimes sound in word war or other tool sounds for word builder. Also for the visually inclined, you could sell alternate skins to the decks of cards for your card games, maybe have a spooky one around Halloween, make the cards look like they are woodcuts or made of papyrus, or something like that.
For the dice game, allow players to buy other dice. These would not be different mechanically but would make different sound effects or, again for the visual players, look different.
Also, depending on how your model is going, maybe even sell the same item for either gold or real money. The gold option would take much longer and the price would be relatively high for what the item is. The money price would allow much more immediate gratification and a lot of people might go for that to get something really cool they wanted. With sales or other things that would reduce the price in real money for a time, you could get people excited. Also, even if they go the gold route, they'll be playing a lot more or watching videos to earn gold so you still win.
Lastly, people might want to make their user page their own so you could sell customized player screens to them. For example, a cat lover might want their screen to reflect that and so you could sell them a template that makes their user profile screen battle-cat themed. Likewise, someone might want the pirate casino thing going and you could sell them a pirate poker theme that they would apply. Also, you could do other things like sell titles to people. Basically, when you had just Word War, the levels were named based on military rank. Do that with all your games and people could turn on instead of saying level 4 alone in their information, it would say level 4: junior contractor, or something like that for someone who bought a word builder set of titles. If you have a fixed level cap in the game where you can't get any more experience, you'll have to make up new names for what you have when you create higher levels, and if it is open ended, just create new categories up higher with wider ranges every now and then.
lastly, earlier I said I thought that there should be more to do in Word Builder that might bring in a multiplayer element. I have a few ideas.
1. The players are given a moderately-difficult randomly-assigned puzzle and are timed in how long it takes them to win.
2. The players are given a randomly assigned puzzle (both the same one to be fair) an given a limited amount of time to get as many of the words as they can, not being allowed to play any farther when time runs out and should some player finish first, they win if they complete it.
3. the players are each given 3 puzzles (the same to each) and are supposed to work in a set amount of time to complete them, overall score at the end of the three puzzles matters, so even if one doesn't finish all of them but the other does, that first one might still win because they found a lot of hidden words.
I just think playing word builder completely by oneself wastes some of its potential.
