ANDROID GAMING!
Went exploring for any board game knock offs on the android marketplace yesterday and with the help of BGG, found a few ok ones.
Condado - Complete rip of San Juan, which is the card game version of Puerto Rico. Is not too bad so far, although I am NOT a good player of Puerto Rico at all as yet.
Blokish - Complete rip of Blokus incl. the name.
Abstract strategy game thing with placing various shaped piece on a board.
Other:
Pirates and Traders - Sort of almost rogue-like spin on Pirates!, pretty cool but hard as hell so far. Barely managed to beat any ships
Dark Nova - This isn't free like the others (although there is a 'lite' version), it looks pretty cool, but yet to play much. Basically space trading type game.
Most likely the above are available on iOS as well for those inclined to 'that' sort of thing.
