1. Somewhat similar to Wii, after every X minutes of game play, display a popup with a one minute timer asking users to take a break. to play non stop ask them to buy a premium version.
2. Ask users to pay for higher levels of game maybe ?

There are no higher game levels. Each round is different.
Can't do a premium version, since there are ongoing server costs. I want those covered by advertising. I don't want to have to fund the servers from now till forever with potentially no future income.
Care to elaborate why the costs exclude premium version? Why couldn't the paying users cover the costs, while the free play is basically your promotion tool (like Dropbox).
Ideally, Android needs a micro-payment system (tied to their service provider billing or something).
