Same applies for the Amazon kindle. The silk browser on the Kindle does not support Flash, but you can play Javascript games for a short game. And you don't have to download dozens or hundreds of Megabytes first.
Below a list of Javascript Games I had adapted for Ipad and Kindle.
Pigs-and-Sties
Sudoku
sznill puzzle
sznill battle
Tower of Hanoi
Memory
Get Across
Corona - a circular nim game
Froxot Pipe Battle
is also available as download for PC
I have programmed also more javascript browser games for other systems
