This thread isn't a place to fight over which is better, its a thread to bring people together

I have recently started playing a game called Homerun Battle 3D on my iPod with a buddy who has an Android phone. This got us thinking about which other games are capable of being played online with people who have different devices or operating systems.

Please add any you may have come across (especially if they are worth playing), if they are paid or free apps and a brief description. If you would like to include a username you go by to hook up with other players please feel free to do so.

So far I have 4 games that work on iOS and Android.

Homerun Battle 3D - FREE w/ ads or Paid w/o ads
10 Strikes and your out! Face off against others online or play offline arcade mode, swing for the fences to increase your score and beat your opponent.

Papaya Farm - FREE
Basic farming game with a garden and a ranch. Plant fruit and veggies, raise animals and sell for a profit. Has a good system of tools which combine your farmed products to create new items worth more money.
Visit your friends farm to plants seeds and share (or steal ) their crop, water their plants or feed their animals for extra points.

Words With Friends - Free w/ ads
A fun turn based scrabble type game where you can have multiple games/opponents going at once.

WordFeud - Free w/ ads
Same as above, Scrabble turn based game and the best one IMO
